Berberine and Dasatinib

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Dasatinib

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

Theoretically, berberine might increase serum levels of drugs metabolized by CYP3A4.
In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, use of berberine with drugs metabolized by CYP3A4 might increase drug levels and increase the risk of adverse effects.
Severity Moderate Likelihood Possible Evidence A

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 Sprycel (dasatinib): your body relies heavily on an enzyme called CYP3A4 to clear this drug out of your system. Berberine appears to slow that enzyme down. So in theory, pairing the two could let dasatinib build up higher than intended, which may turn up its side effects, things like fluid retention, low blood cell counts, bruising or bleeding, diarrhea, and tiredness.

I'll be honest, this is mostly a theoretical concern drawn from lab work and early studies, not from people taking these two together. But dasatinib is a serious cancer medicine with a fairly tight dosing window, so I wouldn't add berberine on your own. Please run it by your oncologist or pharmacist first.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

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.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

From our pharmacist’s overview on the Dasatinib page

“Grapefruit is the first thing I would take off the table for anyone on dasatinib (Sprycel, Phyrago), a targeted leukemia therapy where a steady blood level is the whole point of treatment. It blocks CYP3A4, the enzyme that clears dasatinib, letting levels climb, and 121 of the 146 supplements on file act on that same pathway.”

Berberine is a yellow plant compound that has shown promise for lowering blood sugar and cholesterol in some studies, but the quality of research varies and it is not a replacement for prescribed medicine. It can cause stomach upset and should be avoided during pregnancy and breastfeeding. Always check with your pharmacist or doctor before starting it, especially if you take other medications.
