Dolutegravir and Carbamazepine (Tegretol 200 mg): interaction and safety
This source-based reference is not a personal treatment recommendation. The relevance and management of an interaction depend on the exact products, route, dose and clinical situation.
Interaction mechanism
Enzyme induction reduces dolutegravir exposure.
Clinical significance and safety
Carbamazepine or efavirenz can reduce dolutegravir exposure and compromise antiviral control. Management depends on integrase-inhibitor treatment and resistance history, so the HIV prescriber must review the complete regimen rather than using a standard self-adjustment.
