POSSIBLY EFFECTIVE

• Poisoning. Oral activated charcoal taken after ingestion of certain drugs reduces systemic drug exposure. However, it is unclear if it affects clinical endpoints such as morbidity or mortality. Details: Taking activated charcoal orally appears to be effective when used as part of standard treatment for some, but not all, acute poisonings (12392,12393,93198,93606,93607,93613,94730). Single doses of activated charcoal, 25-100 grams in adults (10-50 grams in children, depending on age), are effective for preventing absorption of some drugs, including acetaminophen, aminophylline, amiodarone, aspirin, atenolol, carbamazepine, digoxin, fluoxetine, indomethacin, phenytoin, valproate, and verapamil, especially if taken within one hour of ingestion (93602,93610,93612,93613,94730,108852). A single dose reduces drug exposure by 38% to 52% when given within 1 hour, by 21% to 35% when given 2-4 hours after ingestion, and by about 14% when given 6 hours after ingestion. These late effects, occurring after oral absorption is complete, are due to enhanced elimination via interruption of enterohepatic circulation and binding of drug that has been actively or passively transported back into the gastrointestinal tract (105543). Multiple-dose activated charcoal, 50-100 grams initially followed by doses of 25 grams every 2 hours or 50 grams every 4 hours, or 10-25 grams per dose in children, is recommended for patients who ingest life-threatening amounts of carbamazepine, dapsone, phenobarbital, quinine, or theophylline. This is based on clinical, animal, and in vitro research showing increased elimination of these drugs (12392,105543). This increased elimination can also reduce levels of drugs that have been given intravenously, with the median half-life being decreased by an average of 45% and the median area under the concentration/time curve (AUC) by an average of 47% (105543). Additional research suggests that multiple-dose activated charcoal may be useful for increasing the elimination of amitriptyline, digoxin, imipramine, moxifloxacin, nadolol, phenytoin, piroxicam, and sotalol. Evidence supporting the use of multiple-dose activated charcoal in aspirin, doxepin, tobramycin, valproate, or vancomycin overdose is limited or conflicting (12392,105543). While activated charcoal may reduce absorption of some toxic agents, there is contradictory evidence about whether it improves clinical outcomes (12392,93200,93601,93613,94730). Administering activated charcoal 50 grams every 6 hours for carbamazepine poisoning decreases the duration of coma by 9 hours, the duration of mechanical ventilation by 12 hours, and the length of hospital stay by 9 hours. However, activated charcoal does not reduce the duration of hospitalization, intensive care admission, vomiting, or mortality when compared with control after oral overdose of benzodiazepines, acetaminophen, or selective serotonin reuptake inhibitors (93200). Other preliminary clinical research in patients with phenytoin toxicity shows that taking activated charcoal 50 grams orally every 4 hours reduces the time to return to therapeutic levels by about 22 hours when compared with control, but without reducing symptoms (93609). In patients with pesticide or yellow oleander seed toxicity, neither single-dose nor multi-dose regimens of activated charcoal reduce mortality, seizures, or the need for intubation when compared with control (93601).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Celiac disease. Although there is interest in using activated charcoal for acute gluten exposure in those with celiac disease, there is insufficient reliable information about the clinical effects of activated charcoal for this purpose.
• Chemotherapy-induced diarrhea. It is unclear if oral activated charcoal is beneficial in patients with chemotherapy-induced diarrhea. Details: Preliminary clinical research in children treated with irinotecan shows that taking activated charcoal 250 mg the night before the first infusion and every 8 hours thereafter until the end of the cycle reduces the risk of diarrhea by 60% when compared with no treatment. Activated charcoal also appears to reduce the risk of severe diarrhea by 92% and to decrease chemotherapy discontinuation by 87% in these patients (93608).
• Cholestasis. It is unclear if oral activated charcoal is beneficial in patients with pregnancy-induced cholestasis. Details: Preliminary clinical research in pregnant patients with cholestasis shows that taking activated charcoal 50 grams orally three times daily for 8 days decreases bile acid levels by about 50%, compared with an increase in those not taking activated charcoal. However, itching was not significantly improved with activated charcoal when compared with control (126).
• Constipation. Oral activated charcoal has only been evaluated in combination with other ingredients; its effects when used alone are unclear. Details: A clinical study in patients with chronic constipation shows that a specific combination product (Nucarb; Wilshire Laboratories Ltd) containing activated charcoal 180 mg, calcium sennosides 50 mg, peppermint oil 0.5 mg, fennel oil 0.5 mg, rhubarb extract 250 mg, and sulfur 50 mg, taken as two tablets at bedtime for one week, followed by 1 tablet at bedtime for 1 week, reduces passing gas, abdominal pain, and sensation of bloating by 81%, 73%, and 72% respectively, when compared with baseline. Sensation of straining, severity of constipation, and feeling of incomplete evacuation were reduced by 69%, 67%, and 54% respectively, when compared with baseline (108853). The validity of this finding is limited by the lack of a comparator group.
• Dyspepsia. Oral activated charcoal has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with functional dyspepsia shows that taking a specific combination product containing activated charcoal 280 mg, simethicone 90 mg, and magnesium oxide 180 mg (Carbosymag, Laboratoires Grimberg) three times daily for one month reduces symptoms of dyspepsia, such as postprandial fullness, epigastric pain, and abdominal bloating, when compared with placebo (93199). Other preliminary clinical research in patients with dyspepsia shows that taking another specific combination product containing activated charcoal 280 mg and simethicone 90 mg (Carbosylane, Laboratoires Grimberg) three times daily for 3 months does not improve overall symptoms of dyspepsia or nausea, but does improve abdominal fullness by 20%, bloating by 20%, and slow digestion by 30%, when compared with placebo (93604).
• Flatulence. It is unclear if oral activated charcoal is beneficial for reducing the occurrence of flatulence. Details: Some preliminary clinical research shows that taking activated charcoal (Requa Charcocaps) 582 mg after a gas-producing meal significantly decreases the number of flatus events when compared with placebo. On average, subjects taking activated charcoal reported less than 3 flatus events over 8 hours, compared with more than 14 flatus events in those taking placebo (12395). However, other preliminary clinical research shows that taking activated charcoal 520 mg at breakfast, lunch, dinner, and bedtime for 7 days does not significantly reduce excessive gas or total flatus events when compared with baseline (12396).
• Hangover. There is no reliable evidence that activated charcoal prevents or treats hangover. Details: Activated charcoal is included in some hangover remedies. However, ethanol adsorbs poorly to activated charcoal (12400).
• Hypercholesterolemia. It is unclear if oral activated charcoal is beneficial in patients with hypercholesterolemia. Details: Some preliminary clinical research in patients with hypercholesterolemia shows that taking activated charcoal 4-32 grams daily for 3 weeks decreases total cholesterol by up to 29% and low-density lipoprotein (LDL) cholesterol by up to 41% when compared with control. The effects of activated charcoal appear to be dose-dependent. Additional clinical research shows that taking activated charcoal 20 grams twice daily for 3 weeks is as effective as cholestyramine 8 grams twice daily for treating hypercholesterolemia (12398), but the combined use of activated charcoal and cholestyramine does not appear to confer additional benefit when compared with either agent alone (12397). However, other research suggests that activated charcoal is not effective for treating hypercholesterolemia (12399). Reasons for the discrepancies are unclear but may relate to the small size of the latter study, and the inclusion of some patients without hyperlipidemia.
• Hyperphosphatemia. Oral activated charcoal might reduce the incidence of hyperphosphatemia in patients with kidney disease. Details: Preliminary clinical research in a small number of patients with stage 3 or 4 chronic kidney disease (CKD) shows that taking activated charcoal 0.6-1.2 grams three times daily for 12 months reduces the risk of hyperphosphatemia by 64% when compared with placebo. Additionally, in CKD patients who develop hyperphosphatemia, use of activated charcoal at the same dose for up to 24 months seems to delay the development of vascular calcification when compared with calcium carbonate, but not when compared with lanthanum carbonate (103193). Other preliminary clinical research in patients on hemodialysis shows that taking activated charcoal for 24 weeks, at a starting dose of 600 mg three times daily, increasing by 300 mg three times daily every 4 weeks until the goal phosphate level is reached, reduces phosphate levels to the goal in over 90% of patients when compared with baseline (93611). The lack of a control group limits the validity of these findings.
• Tooth whitening. It is unclear if toothpaste containing activated charcoal is beneficial for tooth whitening. Details: A small clinical study in adults with dental stains due to factors such as coffee or tobacco use shows that using a toothpaste containing activated charcoal (Blanx Black, Coswell SpA) twice daily for 3 months reduces visible staining, dental plaque, and bleeding when compared to baseline, but not when compared with a micro-cleaning crystal toothpaste (Sensation White, Colgate) (111718).
• Wound healing. Research on the use of activated charcoal-containing dressings for wound healing is limited and conflicting. Details: One preliminary clinical study shows that treating chronic venous leg ulcers with activated charcoal-containing dressings (Actisorb, Systagenix) for 6 weeks reduces ulcer size by 17% when compared with control occlusive or semi-occlusive dressings containing antibacterial or antiseptic agents (94731). However, other preliminary clinical research shows that treating pressure ulcers or venous leg ulcers with activated charcoal-containing dressings (Actisorb and Actisorb Silver 220, Systagenix) for 4 weeks does not significantly improve wound healing when compared with a hydrocolloid dressing (93603). More evidence is needed to rate activated charcoal for these uses.

General ...Orally, activated charcoal is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, black stools, bloating, constipation, and flatulence.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal obstruction and pulmonary aspiration.

Gastrointestinal ...The most common adverse reactions reported with activated charcoal are gastrointestinal in nature. Constipation appears to be the most frequent complaint, but is typically transient. Black stools, abdominal pain, bloating, and flatulence have also been reported (12392,12398,93611,103193). Rarely, activated charcoal may lead to gastrointestinal obstruction (12392).

Pulmonary/Respiratory ...Rarely, pulmonary aspiration has been reported in patients taking activated charcoal orally. This may happen if activated charcoal is regurgitated or if a misplaced nasogastric tube delivers activated charcoal to the lungs rather than the stomach (12392).
