• Allergic rhinitis (hay fever). Although there has been interest in using oral black pepper for allergic rhinitis, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Asthma. Although there has been interest in using oral black pepper for asthma, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Athletic performance. Oral black pepper has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial in untrained males shows that taking a supplement containing black pepper extract 10 mg, caffeine 400 mg, capsicum extract 66.7 mg, and niacin 40 mg as a single dose prior to exercise does not improve strength, time to exhaustion, or maximal oxygen consumption when compared with placebo (37873).
• Depression. Although there has been interest in using oral black pepper for depression, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Diarrhea. Although there has been interest in using oral black pepper for diarrhea, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Dysmenorrhea. Although there has been interest in using oral black pepper for dysmenorrhea, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Dyspepsia. Although there has been interest in using oral black pepper for dyspepsia, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Fall prevention. It is unclear if inhaling black pepper oil as aromatherapy is beneficial for fall prevention in older adults. Details: One small clinical study in older adults shows that applying black pepper oil near the right side of the nose as an olfactory stimulant improves stability while the eyes are closed during a one-minute trial when compared with the application of water. The improvement with black pepper oil is comparable to the improvement seen with the application of lavender oil (29160). It is unclear if any benefit persists after inhalation of black pepper oil.
• Fatigue. It is unclear if oral black pepper is beneficial in patients with fatigue. Details: One small clinical trial in adults with below-average energy levels shows that taking black pepper 2 grams as a single dose does not improve sustained attention, motivation to perform cognitive tasks, or feelings of mental energy and mental fatigue when compared with placebo (91731).
• Flatulence. Although there has been interest in using oral black pepper for flatulence, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Headache. Although there has been interest in using oral black pepper for headache, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Insect bite. Topical black pepper has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial shows that applying a specific product (Trikatu) containing black pepper, long pepper, and ginger, as well as camphor, eucalyptus oil, and menthol, directly to mosquito bites does not reduce papule size, erythema, edema, or pruritis when compared with a control compound containing the same base ingredients but without the pepper and ginger components (89893).
• Obesity. Although there has been interest in using oral black pepper for obesity, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Pain (chronic). Although there has been interest in using topical black pepper for chronic pain related to various etiologies, including osteoarthritis, postherpetic neuralgia, and peripheral neuropathy, there is insufficient reliable information about the clinical effects of black pepper for these conditions.
• Rhinosinusitis. Although there has been interest in using oral black pepper for rhinosinusitis, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Sexual desire. Although there has been interest in using oral black pepper for increasing sexual desire, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Smoking cessation. It is unclear if inhaling black pepper essential oil as aromatherapy is effective for smoking cessation. Details: One small clinical trial in adult male smokers who were deprived from smoking overnight shows that inhaling a vapor from the essential oil of black pepper, as needed over a 3-hour period, reduces cigarette cravings, negative feelings, and anxiety when compared with a placebo vapor (29159). Another small clinical study in patients addicted to dipping, chewing, or smoking tobacco shows that placing a drop of black pepper essential oil on tissue paper and inhaling for 2 minutes at least three times a day for 3 days reduces nicotine cravings when compared to baseline (90502).
• Swallowing dysfunction. It is unclear if inhaling black pepper oil as aromatherapy is beneficial in patients with swallowing dysfunction. Details: One small clinical study in post-stroke residents of nursing homes shows that one minute of olfactory stimulation with black pepper oil before each meal for 30 days decreases swallowing reflex latency by 11 seconds and increases the number of swallowing movements by 3.3 when compared to baseline (29161). A small clinical trial in children with neurological disorders who were on long-term enteral nutrition shows that applying black pepper oil to the nostrils or nasal cavity for one minute improves the amount of oral intake and swallowing movement in 63% of patients. Although oral intake increased, the need for enteral nutrition was not eliminated (29162).
• Vitiligo. It is unclear if topical piperine oil, a constituent of black pepper, is beneficial in patients with vitiligo. Details: A small clinical study in patients with vitiligo shows that applying piperine oil 1% daily in addition to receiving narrowband ultraviolet B (NB-UVB) light therapy every other day for 3 months improves repigmentation more rapidly when compared with using NB-UVB alone (103820). More evidence is needed to rate black pepper for these uses.

• Allergic rhinitis (hay fever). Although there has been interest in using oral bromelain for allergic rhinitis, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Aromatase inhibitor-induced arthralgia. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with aromatase inhibitor-induced arthralgia shows that taking a specific combination product (Opera, Gam Farma), providing bromelain 20 mg, alpha-lipoic acid 240 mg, Boswellia serrata 40 mg, and methylsulfonylmethane 200 mg, daily for 6 months reduces arthralgia symptoms when compared to baseline (109570). The validity of these findings is limited by a lack of placebo control group. Further, it is unclear if these findings are due to bromelain, other ingredients, or the combination.
• Burns. Preliminary clinical research shows that topical bromelain is beneficial for burn debridement. However, it is unclear if topical bromelain is beneficial for scar prevention. Details: Preliminary clinical research and chart reviews show that gels formulated with proteolytic enzymes derived from bromelain (Debridase or NexoBrid, MediWound Ltd.) applied under an occlusive dressing for 4 hours help debride burns, including chemical and electrical burns, in children and adults (18275,91113,103297,108149). Further, a meta-analysis of up to 5 lower- to moderate-quality clinical and observational studies in children and adults with deep burns shows that enzymatic debridement with a specific bromelain based proteolytic enzyme gel applied once or twice for a 4 hour period reduces eschar time by approximately 7 days and reduces the relative risk of surgical excision, and autografts by 83%, and 60%, respectively, when compared with standard of care (e.g., surgical and non-surgical procedures) (115870). The validity of these results is limited by significant heterogeneity across clinical studies, including differences in the location of burns and extent of total body surface area affected.
• Cancer. Although there has been interest in using oral bromelain for cancer, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Chemotherapy-induced peripheral neuropathy. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with chemotherapy-induced peripheral neuropathy shows that taking a specific product (Opera, Gamfarma s.r.l.) containing bromelain 20 mg, alpha-lipoic acid 240 mg, methylsulfonylmethane (MSM) 200 mg, and boswellia 40 mg daily for 12 weeks reduces overall pain when compared with baseline (96449). The validity of these findings is limited by the lack of a control group. Additionally, it is not clear if benefit is due to alpha-lipoic acid, the other ingredients, or the combination.
• Chronic venous insufficiency. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: An observational study in adults with chronic venous insufficiency using compression stockings shows that taking a specific supplement containing bromelain dry extract 50-200 mg, Baikal skullcap, and horse chestnut (Lenidase, Enfarma), dose adjusted based on severity, daily for up to 90 days, improves severity of lower extremity symptoms (e.g., inflammation, pain, varicose veins, vessel induration) when compared with the use of compression stockings alone (115869). It is unclear if these benefits are due to bromelain, the other ingredients, or the combination.
• Diabetes. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small observational study in patients with a family history of type 1 diabetes found that taking a specific product (Mucos Pharma) containing bromelain 90 mg. rutin 100 mg, and trypsin 48 mg daily for 24 months is not associated with reduced incidence of type 1 diabetes at 8 years (99472).
• Diabetic foot ulcers. Although there has been interest in using topical bromelain for diabetic foot ulcers, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Exercise-induced muscle soreness. It is unclear if oral bromelain is beneficial for preventing exercise-induced muscle soreness. Details: One small clinical study shows that taking bromelain 300 mg three times daily, immediately following an intense exercise regimen, does not reduce delayed onset muscle soreness and has no effect on pain, flexibility, or skeletal weakness when compared with either ibuprofen 400 mg three times daily or placebo (10622). However, a small clinical study shows that taking a combination protease tablet containing bromelain 50 mg, trypsin 75 mg, papain 50 mg, amylase 10 mg, lipase 10 mg, lysosome 10 mg, and chymotrypsin 2 mg, four times in one day before downhill running, can improve recovery of contractile muscle function and decrease muscle soreness when compared with placebo (67838). It is unclear if these effects are due to bromelain, other ingredients, or the combination.
• Exercise-induced respiratory infections. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in non-elite male runners shows that taking a combination product (Wobenzym Plus, Mucos Pharma) providing bromelain 540-1080 mg, rutin 600-1200 mg, and trypsin 288-576 mg daily for 3 weeks, starting one week before a marathon, does not reduce the risk of a post-race respiratory tract infection when compared with placebo (96766).
• Kidney stones (nephrolithiasis). It is unclear if oral bromelain is beneficial for kidney stone expulsion. Details: Observational research in patients with 4-10 mm kidney stones found that adding bromelain to tamsulosin is associated with a 12% increased rate of spontaneous stone expulsion when compared to tamsulosin alone (100752).
• Knee pain. It is unclear if oral bromelain is beneficial for knee pain. Details: Preliminary clinical research shows that taking bromelain (Bromelin, Lichtwer Pharma Ltd.) orally for 30 days can reduce mild, acute (duration of less than 3 months) knee pain in otherwise healthy patients when compared to baseline. A daily dose of 400 mg seems to be more effective than 200 mg daily for relieving pain, stiffness, and physical function of the knee, with reductions in symptom scores of 59% and 41%, respectively (11457).
• Lymphedema. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some clinical research in patients who have undergone a mastectomy shows that taking a specific combination product containing bromelain, rutin, pancreatin, papain, trypsin, and chymotrypsin (Wobenzym N, Mucos Pharma) daily for 7 weeks reduces arm swelling associated with lymphedema when compared with diuretics (24560). Other preliminary clinical research in patients with primary or secondary lymphedema of the upper or lower limbs shows that taking a different combination product containing bromelain 100 mg, rutin 300 mg, and sweet clover 100 mg daily for 6 months decreases pitting, limb volume, pain, and quality of life when compared to baseline (103298). The validity of these results is limited by the lack of a control group. Additionally, it is unclear if these findings are due to bromelain, other ingredients, or the combination.
• Multiple sclerosis (MS). Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A preliminary clinical study in patients with relapsing-remitting MS shows that taking an enzyme combination containing bromelain 90 mg, rutin 100 mg, and trypsin 48 mg per tablet for at least 3 months does not affect the progression of disability, relapse rate, or central nervous system lesions when compared with placebo (99468). The validity of these results is limited by the short duration of treatment.
• Ocular floaters. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in patients with spontaneous symptomatic vitreous opacities (ocular floaters) shows that taking oral mixed fruit enzyme capsules containing bromelain 190 mg, papain, and ficin once, twice, or three times daily for 3 months eliminates floaters in 55%, 63%, and 70% of patients, respectively, when compared with an elimination rate of 5% with vitamin C as a control. Additionally, patients with vitreous hemorrhage-induced symptomatic vitreous opacities taking the mixed fruit enzyme capsules 3 times daily for 3 months reduced intraocular blood by 56% and improved visual acuity, but these effects were not found for lower doses and shorter durations when compared with a control (111650). It is unclear if these effects are due to bromelain, other ingredients, or the combination.
• Osteoarthritis. It is unclear if oral bromelain is beneficial for osteoarthritis. Details: A small clinical trial shows that taking bromelain 800 mg daily for 12 weeks as an adjunctive treatment for moderate to severe knee osteoarthritis is no more effective than placebo for improving symptom scores (18274). Other preliminary clinical research shows that taking bromelain 500 mg daily for 4 weeks for mild to moderate knee osteoarthritis is less effective than diclofenac 100 mg daily for improving quality of life, joint pain, and joint function (96216). However, preliminary clinical research shows that oral combination products containing bromelain can reduce pain and improve function in knee osteoarthritis (6252,91104,91106,99467,99477,103299). Bromelain 180 mg has been used in combination with trypsin 144 mg and rutin 200 mg (Phlogenzym, Mucos Pharma GMBH; Wobenzym, Mucos Pharma GmbH) three times daily for 3-12 weeks, with effects comparable to diclofenac, usually taken as 50 mg three times daily for one week, then twice daily thereafter. This product also reduces the need for rescue analgesics by 95% when compared with placebo (6252,91104,99467,99477). Other studies have used a specific combination supplement (AINAT, Laboratoire de Rhumatologie Appliquée) containing Devil's claw 600 mg, turmeric 400 mg, and bromelain 300 mg, taken 2-3 times daily for 2-8 weeks (91106) or a combination of bromelain 250 mg and papain 250 mg (Nature's Life Bromelain & Papain, NutraMarks, Inc.) twice daily, plus aceclofenac 100 mg twice daily for 6 weeks (103299).
• Pain (acute). It is unclear if oral bromelain is beneficial for acute pain. Details: A meta-analysis of 9 small clinical studies in patients experiencing acute pain due to various etiologies shows that taking bromelain slightly improves subjective pain scores and allows patients to open their mouth wider after oral operations when compared with a control (113513).
• Parturition. Although there has been interest in using oral bromelain for shortening the duration of labor, there is insufficient reliable information about the clinical effects of bromelain for this purpose.
• Periodontitis. It is unclear if oral bromelain is beneficial for periodontitis. Details: A very small clinical study in adults with periodontitis shows that taking bromelain 500 mg (Anaheal) twice daily for one week after undergoing pocket elimination surgery reduces bleeding on probing but does not improve gingival index, plaque index, or probing pocket depth when compared with placebo when assessed five weeks after surgery (111691). The validity of these effects is limited by a very small sample size and inadequate statistical power.
• Pityriasis lichenoides chronica (PLC). It is unclear if oral bromelain is beneficial for PLC. Details: A case series suggests that taking bromelain 40 mg orally three times daily for one month, then twice daily for a second month, then once daily for a third month, helps treat episodes of PLC when compared to baseline (18280).
• Postoperative pain. While evidence is mixed, some small clinical studies suggest that oral bromelain reduces postoperative pain after some oral surgeries. Details: Meta-analyses and clinical research in a small number of patients undergoing wisdom tooth extraction shows that bromelain modestly reduces pain for up to 8 days when compared with control (91109,91110,100750,100751). In contrast, several other small clinical studies show that taking bromelain does not reduce pain after wisdom tooth extraction when compared with placebo (91107,96214,96215). These studies might not have been sufficiently powered to detect a smaller effect. Meta-analyses also suggest that bromelain does not appear to have a significant effect on postoperative swelling or trismus (100750,100751). Additionally, multiple clinical studies in patients undergoing oral procedures, including crown lengthening or root canal surgery, shows that bromelain 160-1500 mg, taken in 2-4 divided doses daily for up to 6 days, reduces dental pain, swelling, and trismus similarly to taking non-steroidal anti-inflammatories (e.g., ketoprofen, diclofenac sodium, aceclofenac, and ibuprofen) (91109,91110,110546,113898,115871,110546). Bromelain, in combination with other ingredients, has also been evaluated for reducing pain after surgery. Several clinical trials in adults undergoing a variety of surgery types, including facial trauma, hernioplasty, oral surgery, and shoulder surgery, show that taking specific combination products (Siben, Brovas, Tenosan) containing bromelain and other ingredients (e.g., freeze-dried pineapple, methylsulfonylmethane, Boswellia serrata) daily for 1 week to 3 months reduces postoperative pain (115868,19322,114687,115304). However, clinical significance is unclear. Additionally, it is unclear if the effect is due to bromelain, other ingredients, or the combination.
• Postoperative swelling. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small preliminary clinical study in patients undergoing surgery of the jaw shows that taking an enzyme combination of bromelain 180 mg, rutin 200 mg, and trypsin 96 mg twice daily for 5 days in addition to standard treatment reduces soft-tissue thickness (indicating the amount of swelling) at most of the nine assessed facial points when compared to control (99476).
• Rhinosinusitis. It is unclear if oral bromelain is beneficial for rhinosinusitis. Details: Several small clinical trials show that short-term and long-term use of bromelain reduces symptoms of acute and chronic sinusitis, especially nasal mucosal inflammation and edema (18276,18277,18278,18279,91105). The trials used bromelain 40 mg orally (usually the product Ananase) four times daily for six days as an adjunct to antibiotics (18276,18278,18279) or 6 bromelain tablets each containing enzymes of 500 International Pharmaceutical Federation (FIP) units for 12 weeks (91105). Bromelain is usually taken in combination with decongestants, antihistamines, and/or antibiotics. However, the studies have a number of methodological problems, and results are inconsistent. Bromelain has also been evaluated as part of a combination product. A small study in patients over 12 years old with chronic sinusitis shows that taking a combination product containing bromelain 200 mg, Boswellia serrata, black currant, and vitamin D (Flogostop Forte, Humana Italia S.p.A) 1-2 times daily for 15-30 days as an adjunctive therapy to inhaled corticosteroids modulates hyperemia of the mucosa, rhinorrhea, and local inflammation when compared with inhaled corticosteroids alone and baseline (111501). It is unclear if these findings are due to bromelain, other ingredients, or the combination.
• Sprains. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A preliminary clinical study in patients with a sprained ankle shows that taking a specific enzyme combination (Phlogenzym, Mucos Pharma) containing bromelain 90 mg, trypsin 48 mg, and rutin 100 mg, or taking different combinations of the individual enzymes three times daily for 10 days, is no more effective for relieving pain than placebo (99473).
• Tendinopathy. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with Achilles tendon insertional tendinopathy shows that taking two sachets of a specific supplement (Tenosan, Agave, Prato, Italy) containing a total of bromelain 100 mg, arginine-L-alpha-ketoglutarate 1000 mg, methylsulfonylmethane (MSM) 1100 mg, hydrolyzed collagen type I 600 mg, vitamin C 120 mg, and Vinitrox 25 mg orally for 60 days improves function and pain when compared with placebo (19321).
• Urinary tract infections (UTIs). Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial shows that a combination of bromelain 50 mg and trypsin 1 mg (Kimotab, Mochida Pharmaceutical), taken in a dose of 8 tablets daily for 2 days, does not improve subjective symptoms of UTIs when compared with placebo (18282).
• Venous leg ulcers. Although there has been interest in using topical bromelain for venous leg ulcers, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Wound healing. It is unclear if enzymatic debridement with bromelain improves the healing of various types of chronic wounds. Details: A meta-analysis of 12 small clinical studies shows that topical bromelain reduces time to complete debridement by around 6 days but has no effect on time to healing when compared with a control (113513). However, the validity of these effects is limited by significant publication bias and a small number of studies per outcome. One small clinical study, included in the analysis above, of patients with chronic wounds related to diabetes, surgery, trauma, or venous insufficiency shows that use of bromelain-based enzymatic debridement (EscharEx, MediWound Ltd), administered as up to ten daily applications of 4 hours each, increases the incidence of complete debridement over the next 6 months to 55% of patients, compared with only 29% of those using the bromelain-free gel. However, there was no difference in changes in wound area, non-viable tissue area, or the incidence or time to complete wound closure (108148). More evidence is needed to rate bromelain for these uses.

• Lactose intolerance. Lactase is effective for reducing gastrointestinal symptoms from consuming lactose in lactose intolerant individuals. Details: Multiple clinical trials show that taking lactase orally is effective for reducing GI symptoms in lactose-intolerant people when used before the consumption of lactose or when added to milk prior to consumption (2371,2372,2373,106669).

• Colic. It is unclear if oral lactase is beneficial in infants with colic. Details: Preliminary clinical research in infants with colic shows that supplementing human milk or formula with lactase (Crosscare Ltd) for 10 days reduces breath hydrogen levels, but not time spent crying, when compared with placebo. However, approximately 30% of infants in this study were considered to be noncompliant. When only infants considered to be compliant were included in the analysis, time spent crying during the 10-day treatment period was reduced by about 6 hours in the lactase group when compared with placebo (96347). In two other small trials, giving 5 drops of a specific lactase formulation (Colibid, RG Pharmaceutica or Yamoo, Walter Bushnell) to infants aged 0-6 months with colic before each feed, or 4 times a day, for 2-4 weeks significantly reduces crying time and fussing time when compared with placebo (104107,112190). However, measures of crying time were based on subjective parent recall only.
• Prematurity. It is unclear if oral lactase is beneficial in premature patients. Details: Clinical research shows that giving fortified human milk or preterm formula treated with lactase drops (Lactaid, McNeil Consumer Products Company) to preterm infants does not improve weight gain, feeding tolerance, weekly length gain, or gain in head circumference by 36 weeks' gestational age or discharge from the hospital (whichever comes first) when compared with giving untreated milk or formula (96346). More evidence is needed to rate lactase for these uses.

• Celiac disease. Although there has been interest in using oral lipase for celiac disease, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Dyspepsia. It is unclear if oral lipase is beneficial for improving symptoms of postprandial distress syndrome. Details: A small clinical trial shows that taking a specific acid-resistant lipase (Amano Enzyme USA) 280 mg immediately before a high-fat meal does not reduce postprandial bloating and nausea when compared with placebo in individuals with postprandial distress syndrome (101900).
• Inflammatory bowel disease (IBD). Although there has been interest in using oral lipase for IBD, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Prematurity. It is unclear if adding a specific form of lipase, recombinant human bile salt-stimulated lipase (rhBSSL), to infant formula improves outcomes in premature infants. Some research suggests a potential increased risk for adverse effects. Details: Human breast milk contains rhBSSL, but it is inactivated when breast milk is pasteurized for donation. Clinical research in infants born before 32 weeks' gestation shows that adding rhBSSL as 8700 units per 100 mL formula or pasteurized breast milk, for 4 weeks does not increase growth velocity, body length, or head circumference over the next 12 months when compared with formula or pasteurized breast milk devoid of lipase. However, the infants who were small for gestational age (SGA), which made up approximately 15% of the study population, grew by an additional 1.9 grams/kg daily on average when compared with placebo (101940). More evidence is needed to rate lipase for these uses.

• Pancreatic insufficiency. Oral prescription pancreatic enzyme products improve digestion in patients with exocrine pancreatic insufficiency due to various causes. It is unclear if non-prescription pancreatic enzyme products would be beneficial; their use is not recommended. Details: Prescription pancreatic enzyme products are effective for improving fat, protein, and total energy absorption in patients with exocrine pancreatic insufficiency due to cystic fibrosis, chronic pancreatitis, pancreas resection or removal, or other conditions (67622,67634,67676,67688,67694,67699,67714) (98667,98674,98676,98677,99115,99116,99118,99119,99120,99122)(99124,99125,99126,99127). Improvement in fat absorption and digestion occurs in as little as 1 week. Symptoms such as gas and abdominal discomfort are also improved in most patients (98667,98674,98677). Various prescription products have been approved by the US Food and Drug Administration (FDA) for this indication (95743). These prescription pancreatic enzyme products are typically used at a starting dose of 500-1000 lipase units/kg body weight per meal to a maximum of 2500 lipase units/kg body weight per meal or 10,000 lipase units/kg body weight daily or 4000 lipase units/gram of fat daily (99130). Despite being beneficial for most patients with exocrine pancreatic insufficiency, there is some evidence that prescription pancreatic enzyme products might not be beneficial in all patients. In patients with pancreatic insufficiency following gastrectomy for gastric cancer, research on prescription pancreatic enzyme products shows conflicting results (67617,95744). Also, a small study shows that taking a prescription pancreatic enzyme product for 26-30 days does not improve time to recovery from pancreatic insufficiency related to acute pancreatitis (99117). However, the small size of most of these studies limit the reliability of the results. One large clinical study shows that taking prescription pancreatic enzyme products for pancreatic insufficiency following pancreatoduodenectomy does not improve body weight or serum albumin levels. However, the dose used in this study was lower than recommended in the US guidelines, and adherence to the prescribed regimen was poor (102322). There is no strong evidence that supplemental forms of pancreatic enzyme products help with digestion in patients with pancreatic insufficiency. Non-prescription pancreatic enzyme products are not recommended for this use.

• Atopic dermatitis (eczema). It is unclear if oral pancreatic enzyme products are beneficial in children with atopic dermatitis. Details: A small clinical study in children with refractory atopic dermatitis and food allergies shows that taking a specific prescription pancreatic enzyme product (Creon, Solvay Pharma) 37,500 or 75,000 protease units with each meal and 18,750 or 37,500 protease units with each snack for 6 weeks reduces the severity of atopic dermatitis when compared with baseline (102321). The validity of this finding is limited by the lack of a comparator group.
• HIV/AIDS. It is unclear if oral pancreatic enzyme products are beneficial in children with HIV. Details: Nutrient malabsorption is common in individuals with HIV/AIDS, possibly leading to malnutrition. Preliminary clinical research in children aged 1-14 years with HIV shows that taking a prescription pancreatic enzyme product (Creon 10,000) 1000 lipase units per gram of digested fat for 2 weeks reduces fecal fat loss when compared with baseline. Although improvement occurred in all of the children, a complete response, resulting in no steatorrhea, occurred in only 33% (99123). The validity of these findings is limited by the lack of a comparator group.
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral pancreatic enzyme products are beneficial in patients with NAFLD following pancreaticoduodenectomy. Details: NAFLD is a common complication post-pancreaticoduodenectomy (PD). A small clinical study in patients who developed NAFLD after PD shows that taking a prescription pancreatic enzyme product (LipaCreon, marketed as Creon in the US) 1800 mg daily for 6 months improves the liver-to-spleen attenuation ratio on computed tomography when compared with baseline, suggesting a reduction in hepatic fat content. Liver function was also improved, and most patients showed improvement in symptoms such as diarrhea (99113). The validity of these findings is limited by the lack of a comparator group. Although another preliminary clinical study shows that taking this prescription product for 12 months is as effective for preventing NAFLD after PD as taking specific non-prescription pancreatic enzyme products, including Politose (Takeda Pharmaceutical Co. Ltd) 1800 mg daily or Toughmac-E (Ono Pharmaceutical Co. Ltd) 3 grams daily for 10-12 months (99112), this study was underpowered and was not necessarily designed to detect between-group differences.
• Pancreatic cancer. It is unclear if oral pancreatic enzyme products improve nutrition status and health in patients with clinically overt exocrine pancreatic insufficiency resulting from pancreatic cancer. Details: Exocrine pancreatic insufficiency can be a complication of pancreatic cancer. One clinical study in patients with unresectable pancreatic cancer shows that taking a prescription pancreatic enzyme product (Norzyme, Nordmark Arzneimittel GmbH & Co. KG; not available in the US) 6-9 capsules daily for 8-24 weeks does not increase body weight, global assessment, quality of life, or survival when compared with placebo (99114). Another preliminary clinical study shows that taking a high-dose pancreatic enzyme product providing 48,000 lipase units per meal for 8 weeks during chemotherapy does not improve body mass index, nutritional parameters, or survival when compared with no treatment (99111). However, in both studies, clinically overt exocrine pancreatic insufficiency was absent in most of the patients. In a study in which clinically overt exocrine pancreatic insufficiency was more prevalent, taking a prescription pancreatic enzyme product (Panzytrat 25,000, Nordmark GmbH; not available in the US) 50,000 lipase units per meal three times daily for 8 weeks appears to increase body weight by about 5% when compared with placebo (67708). More evidence is needed to rate pancreatic enzyme products for these uses.

General ...Orally, black pepper seems to be well tolerated when used in the amounts found in food or when taken as a medicine as a single dose. Topically and as aromatherapy, black pepper oil seems to be well tolerated.
Most Common Adverse Effects:
Orally: Burning aftertaste, dyspepsia, and reduced taste perception.
Inhalation: Cough.
Serious Adverse Effects (Rare):
Orally: Allergic reaction in sensitive individuals.

Gastrointestinal ...Orally, black pepper can cause a burning aftertaste (5619) and dyspepsia (38061). Single and repeated application of piperine, the active constituent in black pepper, to the tongue and oral cavity can decrease taste perception (29267). By intragastric route, black pepper 1.5 grams has been reported to cause gastrointestinal microbleeds (29164). It is not clear if such an effect would occur with oral administration.

Immunologic ...In one case report, a 17-month-old male developed hives, red eyes, facial swelling, and a severe cough following consumption of a sauce containing multiple ingredients. Allergen skin tests were positive to both black pepper and cayenne, which were found in the sauce (93947).

Ocular/Otic ...Topically, ground black pepper can cause redness of the eyes and swelling of the eyelids (5619).

Pulmonary/Respiratory ...When inhaled through the nose as an olfactory stimulant, black pepper oil has been reported to cause cough in one clinical trial (29162).

General ...Orally, bromelain seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, flatulence, gastric upset, headache.
Topically: Pruritus, urticaria.

Dermatologic ...Topically, bromelain may cause dermal allergic reactions including urticaria, pruritus, and skin swelling (9184). Redness, swelling, burning, pain at the application site, and cellulitis have also been reported rarely (108148,113513). In one case, a fixed drug eruption with pruritis near the groin was reported in a 33-year-old male taking bromelain 50 mg orally daily for 10 days. After discontinuation of bromelain and treatment with topical corticosteroid, the lesion resolved. Upon re-challenge with bromelain, the lesion reappeared in the same area (103300).
In another case report, a 61-year-old male with a history of chronic lower leg ulceration secondary to chronic venous hypertension and recurrent deep vein thrombosis on rivaroxaban presented with a deep-dermal burn on his lower calf. Bromelain-based topical enzymatic debridement agent Nexobrid 2 grams was applied to the burn site. Thirty minutes later, the patient experienced two instances of hemorrhage at the site of debridement. The patient was stabilized and treated with fluids, packed red cells, and tranexamic acid, and then the Nexobrid was removed (111656). Caution should be used in patients with underlying coagulopathies.

Gastrointestinal ...Orally, bromelain may cause gastrointestinal disturbances, including diarrhea, nausea, vomiting, flatulence, and abdominal pain (9184,18274,18282,96216,113513).

Immunologic ...Immunoglobulin E (IgE)-mediated allergic reactions to bromelain may occur (9184).
If inhaled, bromelain may cause sensitization and allergic reactions such as asthma (37199,37215,37233). In case reports of occupational inhalation of bromelain, additional allergic symptoms included difficulty swallowing, throat itching, eye irritation, and rhinitis (37214).

General ...No adverse effects have been reported in adults. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.

Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).

General ...Orally, prescription pancreatic enzyme products are generally well tolerated when used at prescribed doses in adults and children.
Most Common Adverse Effects:
Orally: Prescription pancreatic enzyme products can cause abdominal pain, constipation, diarrhea, dry mouth, flatulence, irritation of the skin around the mouth and anus, nausea, steatorrhea, and vomiting.
Topically: Pancreatic enzyme product powder is irritating to the skin, eyes, mucus membranes, and respiratory tract. Pancreatic enzyme products that are held in the mouth prior to swallowing can cause irritation of the mucosa, including ulceration and stomatitis.
Serious Adverse Effects (Rare):
Orally: Prescription pancreatic enzyme products can worsen glucose control. Extremely high doses have been associated with fibrosing colonopathy and high uric acid levels in blood and urine.
Topically: Inhalation of dust containing pancreatic enzyme products has been associated with asthma, bronchospasm, and pulmonary hypersensitivity reactions.

Dermatologic ...Orally, rash or skin conditions have been reported rarely in individuals taking prescription pancreatic enzyme products (67709,98667). A pruritic rash occurred in one patient taking a prescription pancreatic enzyme product in one clinical trial; this event was considered by the investigators to be possibly related to treatment (98667). Erythema also occurred in an 84-year-old patient who had taken a digestive enzyme supplement containing pancreatic enzymes and other enzymes (67709). In a case report, taking a supplemental form of pancreatic enzymes also containing hemicellulose and dried ox bile extract powder (Festal, Handok Inc) was thought to be the cause of an acute generalized exanthematous pustulosis (AGEP). The patient required an antihistamine and an oral and topical corticosteroid. Since this product contained more than one ingredient, the role of the pancreatic enzymes in this specific adverse event is unclear (98675).
Topically, exposure to pancreatic enzyme product powder is irritating to the skin. Hypersensitivity reactions such as skin rash have been reported (15).

Endocrine ...Orally, prescription pancreatic enzyme products may cause hypoglycemia or hyperglycemia in some patients (67622,98676,98677). In a double-blind trial of a prescription pancreatic enzyme product compared with placebo in patients with unresectable pancreatic cancer and associated pancreatic duct obstruction, one patient developed diabetes during the study period (67708).

Gastrointestinal ...Orally, prescription pancreatic enzyme products can cause abdominal pain, constipation, diarrhea, dry mouth, irritation of the skin around the mouth and anus, flatulence, nausea, steatorrhea, and vomiting. However, these symptoms can be controlled by following prescription dosing recommendations (67617,67618,67645,67648,67651,67653,67657,67666,67714,98667)(98676,99115,99117,99123,99130). Doses of higher than 2500 lipase units/kg body weight per meal are not recommended unless medically necessary in order to prevent serious side effects, including fibrosing colonopathy and colonic strictures. These side effects are associated with the higher doses of lipase in prescription pancreatic enzyme products (2382,67677,67678,67679,67680,67682,67689,67690,67696,67701,99130).
Topically, pancreatic enzyme products that are held in the mouth prior to swallowing can cause irritation of the mucosa, including ulceration and stomatitis (15).

Hematologic ...Orally, severe neutropenia has been reported with a pancreatic enzyme product. In one case report, a 61-year-old patient taking a prescription pancreatic enzyme product for chronic pancreatitis developed agranulocytosis that persisted despite a trial of filgrastim. Upon discontinuation of the pancreatic enzyme product, marked improvement in neutropenia occurred within 7 days, with full resolution within 6 weeks (107411).

Neurologic/CNS ...Orally, headache and dizziness have been reported rarely in individuals taking prescription pancreatic enzyme products (67618,98667,99120).

Ocular/Otic ...Topically, exposure to pancreatic enzyme product powder is irritating to the eyes. Hypersensitivity reactions such as watery eyes have been reported (15).

Pulmonary/Respiratory ...Topically, exposure to pancreatic enzyme product powder is irritating to the respiratory tract. Hypersensitivity reactions such as sneezing have been reported (15). Inhalation of dust containing pancreatic enzyme products has been associated with allergic rhinitis, asthma, bronchospasm, and pulmonary hypersensitivity reactions (11768,11769,67641).

Renal ...Orally, extremely high doses of pancreatic enzyme products containing more than 10,000 lipase units/kg body weight daily have been associated with high uric acid levels in blood and urine (67673,67693,67705). Rarely, kidney pain has been reported (98667).
