Interaction report

Bael and Acetaminophen, Caffeine, Codeine, Salicylamide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Bael interacts with whole categories of medication. Acetaminophen, Caffeine, Codeine, Salicylamide falls into 2 of those categories, so it can interact with Bael in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Minor).

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Acetaminophen, Caffeine, Codeine, Salicylamide

Acetaminophen, Caffeine, Codeine, Salicylamide falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Bael interacts with.

Bael extract and its constituent marmesinin inhibited cytochrome P450 1A2 (CYP1A2) activity in vitro. So far, this interaction has not been reported in humans. Theoretically, bael might increase levels of drugs metabolized by CYP1A2.
Some drugs metabolized by CYP1A2 include amitriptyline (Elavil), haloperidol (Haldol), ondansetron (Zofran), propranolol (Inderal), theophylline (Theo-Dur, others), verapamil (Calan, Isoptin, others), and 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.

Here's the piece that matters in your combo pill: caffeine is cleared by a liver enzyme called CYP1A2, and lab studies (test tube only) suggest bael may slow that enzyme down. In theory, that could let caffeine linger a bit longer than usual, so you might notice more of its typical effects, like jitteriness, a racing or pounding heartbeat, trouble sleeping, or feeling wired.

I want to keep this in perspective, though. This is rated a minor interaction, and it has only been seen in the lab, never reported in real people. Food amounts of bael are unlikely to cause trouble. Concentrated bael supplements are the bigger question mark. The codeine, acetaminophen, and salicylamide parts aren't really affected here. If you want to use bael regularly, just run it by your pharmacist first.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Acetaminophen, Caffeine, Codeine, Salicylamide also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

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

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

This combo pill packs a lot in, but the piece that matters most here is the codeine. Codeine is what we call a prodrug, meaning your body has to convert it into morphine before it does much of anything. That activation step relies mainly on a different enzyme (CYP2D6), not the CYP3A4 enzyme that lab studies suggest bael may slow down. So even in theory, the effect on your pain relief is murky rather than straightforward.

Honestly, this is a very weak signal. The only evidence comes from test-tube studies, with nothing reported in real people, and the interaction is rated minor. Culinary amounts of bael fruit are unlikely to matter at all. Still, since codeine can cause drowsiness, constipation, and slowed breathing, it's worth a quick word with your pharmacist before adding concentrated bael supplements.

  • 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).

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.
