Résumé

Fluconazole inhibits several enzymes involved in ospemifene clearance and increases its exposure. Labeling advises avoiding fluconazole, which is a dual CYP3A4 and CYP2C9 inhibitor, because of the higher exposure and the risk of adverse effects including thromboembolic events and endometrial effects.

Ce que signifie cette interaction, en termes simples

Fluconazole and Ospemifene can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Fluconazole belongs to Anti Fungals; Ospemifene belongs to Endocrine.

Niveau de preuve: Moderate

Pourquoi elle survient

Fluconazole inhibits CYP3A4, CYP2C9 and CYP2C19, which metabolize ospemifene.

Conduite à tenir

Avoid concomitant use with fluconazole where possible. If an antifungal is needed, use a short course of an agent that does not inhibit these enzymes or withhold ospemifene.
