Summary
Eslicarbazepine may reduce ospemifene exposure via enzyme induction, potentially reducing efficacy. CYP2C19 inhibition could partly counter this, so the net effect is uncertain.
What this interaction means in plain words
Eslicarbazepine and Ospemifene can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Eslicarbazepine belongs to Central Nervous System; Ospemifene belongs to Endocrine.
Why it happens
Eslicarbazepine induces CYP3A4 and inhibits CYP2C19, both involved in ospemifene metabolism, with an uncertain net effect.
What to do
Monitor for reduced symptom relief of dyspareunia or vaginal dryness and reassess therapy if the response is inadequate.
