Ce que signifie cette interaction, en termes simples
Cenobamate and Levonorgestrel 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.
Cenobamate belongs to Central Nervous System; Levonorgestrel belongs to Endocrine.
