Peppermint and Solifenacin succinate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Solifenacin succinate

Solifenacin succinate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Peppermint interacts with.

Theoretically, peppermint might increase the levels of CYP3A4 substrates.
Clinical research in healthy volunteers shows that a single dose of peppermint oil 600 mg inhibits CYP3A4 enzymes and increases the AUC of felodipine, a CYP3A4 substrate. However, in vitro research suggests that peppermint oil only inhibits CYP3A4 at very high concentrations.
Severity Moderate Likelihood Possible Evidence B

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 relies on an enzyme called CYP3A4 to clear solifenacin (Vesicare) from your system. Concentrated peppermint oil supplements may slow that enzyme down a bit. If that happens, solifenacin could hang around longer than usual, and you might notice more of its typical side effects, like dry mouth, constipation, blurred vision, or feeling lightheaded.

Honestly though, this is on the gentle end of the worry scale. The evidence is mostly theoretical, and lab studies suggest peppermint only blocks this enzyme at very high amounts. A peppermint tea or a mint candy is very unlikely to matter. If you take enteric-coated peppermint oil capsules regularly, just mention it to your pharmacist or doctor so they can keep an eye on things.
