Bael and Finasteride

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Finasteride

Finasteride 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 with bael and finasteride. Your liver uses an enzyme called CYP3A4 to help break down finasteride, and lab studies suggest compounds in bael may slow that enzyme down a bit. If that happened in your body, finasteride could clear a little more slowly and build up slightly, which in theory might nudge up its usual effects like reduced libido, trouble with erections, or breast tenderness.

The good news: this is only seen in test tube and animal work, never reported in real people, and it's rated a minor interaction. Food amounts of bael are very unlikely to matter. Still, if you want to take concentrated bael supplements regularly, run it by your pharmacist or doctor first.

  • 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.

From our pharmacist’s overview on the Finasteride page

“The supplement list for finasteride (Propecia, Proscar) is one I would read carefully rather than skim, because three of its 138 entries are rated major. Almost everything here works through the same liver enzyme, CYP3A4, that clears finasteride.”

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 Finasteride

What Is Finasteride Used For?

Brand names: Propecia, Proscar

Finasteride tablets (including the brand Proscar) are used in men with an enlarged prostate (benign prostatic hyperplasia, or BPH) to improve urinary symptoms, lower the risk of acute urinary retention (a sudden inability to urinate), and reduce the need for prostate surgery. Finasteride tablets may also be used alongside the alpha-blocker doxazosin to slow the progression of BPH symptoms.

Propecia (and finasteride 1 mg coated tablets) is indicated for the treatment of male pattern hair loss (androgenetic alopecia) in men only. Propecia is not approved for use in women, and its effectiveness for hair loss at the temples has not been established. Finasteride is not approved for the prevention of prostate cancer.
