Cranberry and Ibrexafungerp Citrate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Ibrexafungerp Citrate

Ibrexafungerp Citrate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Cranberry interacts with.

Theoretically, cranberry might increase the levels and adverse effects of CYP3A4 substrates.
A case of upper back pain, rhabdomyolysis, and abnormal liver function has been reported for a patient taking atorvastatin, a CYP3A4 substrate, in combination with cranberry juice 16 ounces daily for 2 weeks. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Also, animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine, a CYP3A4 substrate, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control.
Severity Moderate 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: your body uses an enzyme called CYP3A4 to break down ibrexafungerp (Brexafemme). Cranberry, in theory, might slow that enzyme down a little. If that happens, your medication could clear more slowly and build up slightly, which in turn could nudge up its usual side effects like nausea, diarrhea, stomach upset, or dizziness.

I want to be honest about the strength of this, though. It's mostly theoretical, based on a single case report with a statin and some animal research, not on ibrexafungerp itself. An occasional glass of cranberry juice or a handful of berries is unlikely to cause trouble. Ibrexafungerp is also a short course, so this rarely becomes a real issue. Still, if you plan to take concentrated cranberry supplements daily, run it by your pharmacist or doctor first.

From our pharmacist’s overview on the Ibrexafungerp Citrate page

“Ibrexafungerp (Brexafemme) treats vaginal yeast infections, often in a single day of pills, and even that short course can be thrown off by the wrong supplement, so this list warrants real care. Three of the 138 ingredients on file rate major, and they pull in opposite directions.”

Cranberry is best known for helping to prevent repeated urinary tract infections (UTIs) in some people, and the evidence here is moderate but mixed. It is not a reliable treatment for an active UTI, which usually needs antibiotics. For most people cranberry products are well tolerated, but check with a pharmacist before relying on them, especially if you have frequent infections.
