Minor Interaction
Medically reviewed by · Updated September 2026
The bottom line Minor

Ostarine has a minor interaction with Miconazole. Theoretically, concomitant use of ostarine with CYP3A4 inhibitors could increase the effects and adverse effects of ostarine, although this is unlikely to be clinically significant.

Ostarine and Miconazole

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

Why this applies to Miconazole

Miconazole falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS — the group Ostarine interacts with.

Theoretically, concomitant use of ostarine with CYP3A4 inhibitors could increase the effects and adverse effects of ostarine, although this is unlikely to be clinically significant.
Ostarine is partially metabolized by CYP3A4. However, clinical research shows that taking itraconazole, a potent inhibitor of CYP3A4, had minimal effects on the levels of ostarine in the body.
Severity Minor Likelihood Unlikely Evidence B

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: Ostarine is partly cleared by a liver enzyme called CYP3A4, and miconazole can slow that enzyme down. On paper, that could let a bit more ostarine build up in your body, which might mean slightly stronger effects and a higher chance of ostarine's known harms like liver stress. So in theory, this points toward more ostarine activity, not less.

In real life, though, this concern is small. When researchers paired ostarine with itraconazole, a much stronger blocker of the same enzyme, ostarine levels barely moved. Most miconazole people use is a cream or suppository (like Monistat) that stays mostly local, so very little reaches your bloodstream. Still, I'd remind you that ostarine itself isn't FDA-approved and has been tied to liver injury. Please loop in your pharmacist or doctor before combining them.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Miconazole page

“Nearly everything on miconazole's (Monistat, Daktarin, Micatin) supplement list runs through one liver enzyme, CYP3A4, and I would give it genuine care rather than a shrug. Miconazole slows that enzyme, so most of the 132 interacting ingredients are ones whose levels can climb alongside it, while a smaller group pushes miconazole itsel…”

About Ostarine

What is Ostarine?

  • Muscle building
  • Athletic performance
  • Fat loss / body recomposition
  • Bodybuilding cycles

Ostarine (also called MK-2866 or enobosarm) is an experimental, unapproved drug known as a SARM (selective androgen receptor modulator), not a true dietary supplement. It is not approved by the FDA, is banned in sports, and has been linked to liver injury and other serious harms, so it is not recommended for general use.
