Bael and Etravirine

Here is the interaction we found between these two, with the evidence behind it.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Etravirine

Etravirine falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Bael interacts with.

Bael and its constituents marmelosin and marmesinin inhibited cytochrome P450 3A4 (CYP3A4) activity in vitro. So far, this interaction has not been reported in humans. Theoretically, bael might increase levels of drugs metabolized by CYP3A4.
Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and numerous others. Use bael cautiously or avoid in patients taking these drugs.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for your HIV medication, etravirine. Your body relies partly on an enzyme called CYP3A4 to process etravirine. In lab studies (test tube only, not in people), compounds in bael appear to slow that enzyme down. If that happened in the body, etravirine could build up a little more than usual, which in theory might mean more of its typical side effects, like rash, nausea, or tingling.

I want to keep this in perspective. This is rated a minor, theoretical concern based only on lab data, and it has never actually been reported in real patients. Eating bael as a food is unlikely to cause trouble. Still, because skipping doses or changing levels of HIV medicine matters, please run a concentrated bael supplement past your pharmacist or doctor first.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

About Bael

What is Bael?

Bael
  • Diarrhea and dysentery
  • Indigestion and other digestive complaints
  • Constipation
  • Blood sugar support
  • General wellness in traditional medicine

Bael is a fruit-bearing tree long used in traditional Indian (Ayurvedic) medicine, mostly for digestive problems like diarrhea and indigestion. Modern human evidence for its medicinal benefits is very limited, so it should be viewed mainly as a food and traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using bael as a supplement, especially if you are pregnant, breastfeeding, or have a health condition.

About Etravirine

What Is Etravirine Used For?

Brand name: Intelence

Etravirine (brand name Intelence) is used to treat HIV-1 infection in people who have already received other antiretroviral (HIV) treatments — meaning it is meant for patients whose HIV has had a chance to develop resistance to earlier therapies. It is always used as part of a combination regimen with other HIV medications, never on its own.

Both the brand Intelence and generic etravirine tablets are approved for adults and for children ages 2 to under 18 who weigh at least 10 kg (about 22 pounds) and who have already been treated with other HIV drugs.
