Theoretically, inhaling eucalyptol may reduce the effectiveness of amphetamines.
 Details
Animal research suggests that inhaling eucalyptol may reduce the levels of amphetamines in the blood (48987).
|
Theoretically, eucalyptus leaf might increase the risk of hypoglycemia.
Details
Animal research suggests that eucalyptus leaf might have hypoglycemic activity, and might have additive effects when used with antidiabetes drugs (12871).
|
Theoretically, eucalyptus might increase the levels of CYP1A2 substrates.
Details
In vitro research suggests that eucalyptus oil might inhibit CYP1A2, although this has not been reported in humans (12479).
|
Theoretically, eucalyptus might increase the levels of CYP2C19 substrates.
Details
In vitro research suggests that eucalyptus oil might inhibit CYP2C19, although this has not been reported in humans (12479).
|
Theoretically, eucalyptus might increase the levels of CYP2C9 substrates.
Details
In vitro research suggests that eucalyptus oil might inhibit CYP2C9, although this has not been reported in humans (12479).
|
Theoretically, eucalyptus might increase the levels of CYP3A4 substrates.
Details
In vitro research suggests that eucalyptus oil might inhibit CYP3A4, although this has not been reported in humans (12479).
|
Theoretically, inhaling eucalyptol might reduce the effectiveness of pentobarbital.
Details
Animal research suggests that inhaling eucalyptol reduces the level of pentobarbital that reaches the brain (48987).
|
Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
Details
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage (110781).

Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.
Details
A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (12115,17603,17604). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).
|
Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.
Details
Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72% (7046,17604). In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31% (17605). Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine (17603). Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (7046). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).
|
Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.
Details
A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females (12154).
|
Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Details
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP (17603,17604). For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90% (7046,12115). Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours (17603,17604).
|
Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.
Details
Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates (12116,15327). In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP) (7046,12115). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.
|
Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.
Details
A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice (14348). Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.

General
...Orally, diluted eucalyptus oil is generally well tolerated, but the undiluted oil can cause toxicity.
Most Common Adverse Effects:
Orally: Diarrhea, nausea, vomiting.
Topically: Burning, itching, redness, stinging.
Serious Adverse Effects (Rare):
Orally: Signs of toxicity can occur with the undiluted oil at doses as low as 1 mL and include central nervous system depression, shallow respiration, rapid pulse, apnea, coma, and death.
Topically: Prolonged exposure or large amounts of eucalyptus oil can cause agitation, ataxia, drowsiness, muscle weakness, seizures, and slurred speech. The risk of toxicity may be greater in children.
Inhalation (as aromatherapy): Seizures.
Cardiovascular ...Orally, one case of premature ventricular contractions has been reported in a previously healthy 29-year-old male who ingested approximately one ounce of eucalyptus oil (48983).
Dermatologic ...Topically, eucalyptus pollen, leaves, oil, and the constituent eucalyptol can cause contact dermatitis in sensitive people (13303,48931,92856,92858,92859,98497). In some cases, symptoms respond to treatment with topical corticosteroids and tacrolimus (92856). In one case report, transient local redness, burning, and irritation was reported in a 4-year-old child who was bathed in water containing eucalyptus oil. The symptoms resolved within one hour of rinsing the skin with clear water (48983). In a clinical study, treatment with a combination of eucalyptus oil and lemon tea tree oil caused burning, redness, itching, or stinging in up to 20% of the patients. Stinging usually resolved within 10 minutes of application and redness within 30 minutes (19188,98492).
Gastrointestinal ...Orally, eucalyptus oil can cause nausea, vomiting, and diarrhea (48983,48993,48995). Abdominal pain has been reported in a trial of the eucalyptus constituent eucalyptol for inflammatory bowel disease (IBD) (48936).
Immunologic
...A case of IgE-mediated exacerbation of asthma and rhinitis symptoms has been reported in a patient who consumed eucalyptus.
Similar worsening of symptoms occurred when the patient inhaled eucalyptus pollen (48957).
Occupational exposure to eucalyptus may cause allergic dermatitis (98497).
Neurologic/CNS
...Orally, eucalyptus oil can cause central nervous system depression, coma, and status epilepticus (12867,48946,48983).
Topically, orally, and by inhalation, eucalyptus oil has been associated with seizures. A systematic review describes the characteristics of 49 children and 61 adults with seizures associated with various routes of administration. Patients with no seizure history were classified as a eucalyptus oil-induced seizure (EOIS), while patients with a history of seizure or susceptibility to seizure were defined as a eucalyptus oil-provoked seizure (EOPS). In EOIS cases, topical use was reported in 74%, inhalation in 22.5%, and ingestion in 3.5%; for EOPS cases, topical use was reported in 79%, inhalation in 16%, and ingestion in 5%. Generalized tonic-clonic seizures are the most prominent type of seizure in EOIS cases (96%). Among EOPS patients, 37% had focal onset motor seizures with impaired awareness, 24% had focal onset aware motor seizures, 13% had focal to bilateral tonic-clonic seizures, and 26% had generalized onset tonic-clonic seizures (107494). One prospective observational study that was included in this systematic review provided additional details on eucalyptus-induced seizures. This study included 18 reports of EOIS and 28 reports of EOPS in adults and children after topical or inhaled use of eucalyptus oil, either alone or in combination with camphor. The time to seizure onset was 0.5-48 hours after topical application, 2-30 minutes after inhalation, and 0.5-6 hours after ingestion. (105028).
One prospective observational study and one case series have described 20 case reports of seizures occurring in children after ingestion of eucalyptus oil. Most of these seizures are generalized tonic-clonic in nature, occur 15-30 minutes after exposure, and do not reoccur following the discontinuation of eucalyptus oil. Seizures have been reported with both overdoses and therapeutic doses (107493,107495) and include cases of both EOIS and EOPS (107495). Additionally, children appear more likely to require intensive care and mechanical ventilation when compared with adult cases (107494).
A case of fever and headache has been reported in a patient who routinely applied a teaspoon of gel containing eucalyptus extract in his throat or nose to treat sore throat or rhinitis (48946).
General

A thorough evaluation of safety outcomes has not been conducted on the use of larger amounts.
Most Common Adverse Effects:
Orally: Epigastralgia and heartburn with the regular consumption of fresh lemon juice.
Dermatologic ...Topically, the application of lemon oil might cause photosensitivity, due to furocoumarin derivative content. This occurs most often in fair-skinned people (11019).
Gastrointestinal ...Orally, fresh lemon juice, taken as 60 mL twice daily, has been reported to cause gastrointestinal disturbances in 37% of patients in one clinical trial, compared with 8% of patients in the placebo group. Specifically, of the patients consuming lemon juice, 21% experienced heartburn and 8% experienced epigastralgia, compared to 1% and 3%, respectively, in the placebo group (107489).
General

Pulmonary/Respiratory
...Orally, consumption of very large amounts of undiluted myrtle leaf oil might lead to respiratory failure and collapse (18).
Topically, facial contact with myrtle oil preparations may cause glottal or bronchial spasm, asthma-like attacks, or respiratory failure in infants and children (18).
General ...Orally, sweet orange juice or fruit seem to be well tolerated. Large amounts of sweet orange peel may be unsafe, especially for children. When inhaled, sweet orange essential oil seems to be generally well tolerated.
Gastrointestinal ...There have been reports of intestinal colic in children following ingestion of large amounts of sweet orange peel (11).
Neurologic/CNS ...There have been reports of convulsions in children following ingestion of large amounts of sweet orange peel (11).
