Feverfew and Miconazole, Zinc Oxide, Petrolatum

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Miconazole, Zinc Oxide, Petrolatum

Miconazole, Zinc Oxide, Petrolatum falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Feverfew interacts with.

Theoretically, feverfew might increase levels of drugs metabolized by CYP3A4.
Laboratory research shows that feverfew might inhibit CYP3A4. So far, this interaction has not been reported in humans.
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 some good news to ease your mind. The product you're asking about (Vusion) is a diaper-rash cream that combines miconazole, zinc oxide, and petrolatum. You smear it on the skin, where it mostly stays put and does its job on the surface. Very little of it gets into the bloodstream.

The interaction on file is a theoretical one: in lab dishes, feverfew may slow down a liver enzyme called CYP3A4, which could let certain swallowed medicines build up. But a topical cream like this isn't really processed by your liver in any meaningful amount, so this concern doesn't realistically apply here. It has never been reported in people. If you ever take feverfew with oral medications, check with your pharmacist, but for this cream you can relax.

About Feverfew

What is Feverfew?

Feverfew
  • Migraine prevention
  • Headache
  • Fever (traditional)
  • Arthritis and joint pain
  • Menstrual discomfort

Feverfew is a daisy-family herb best known for migraine prevention, where some studies suggest it may modestly lower how often migraines occur, though the evidence is mixed. It is generally well tolerated for short-term use in most adults but should be avoided during pregnancy and breastfeeding and by people allergic to ragweed and related plants. Talk to your pharmacist or doctor before starting it.
