Peony and Mometasone

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Mometasone

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

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect 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 the gist with peony and your mometasone. Peony has been shown in lab and animal tests to gently slow down a liver enzyme called CYP3A4, which is one of the pathways that breaks down mometasone. In theory, if that enzyme runs slower, more of the drug could hang around, nudging its effects up a bit. Mometasone is a corticosteroid, so the worry would be steroid-type side effects.

But here's the reassuring part. Your mometasone is likely a topical cream or ointment (Elocon), and very little gets absorbed into your bloodstream when used on the skin. That means this enzyme effect, which has only been seen in test tubes and not in people, is unlikely to cause you real trouble. Still, it's worth a quick chat with your pharmacist to be safe.
