Cranberry and Buproprion, Dextromethorphan

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Buproprion, Dextromethorphan

Buproprion, Dextromethorphan 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

Auvelity is a combo of dextromethorphan and bupropion. The interesting part here is that the bupropion is actually there on purpose to slow down how fast your body clears the dextromethorphan, which keeps it working in the brain. The cranberry concern on file is about CYP3A4, but dextromethorphan is mainly handled by a different enzyme (CYP2D6), so this particular cranberry interaction is mostly theoretical and rests on weak, anecdotal evidence.

In plain terms, an occasional glass of cranberry juice is very unlikely to cause trouble. If you drink large amounts daily or use concentrated cranberry supplements, just mention it to your pharmacist so they can keep an eye out for things like dizziness, jitteriness, or nausea. Don't change anything on your own.

About Cranberry

What is Cranberry?

Cranberry
  • Urinary tract infection prevention
  • Bladder health
  • Antioxidant support
  • Source of vitamin C

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.
