Sintesi

Armodafinil may reduce etonogestrel concentrations by inducing CYP3A4, which could lower contraceptive reliability. Labeling for armodafinil warns about reduced efficacy of hormonal contraceptives during and for a time after therapy.

Cosa significa questa interazione in parole semplici

Armodafinil and Etonogestrel 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.

Armodafinil belongs to Central Nervous System; Etonogestrel belongs to Endocrine.

Livello di evidenza: Moderate

Perché avviene

Induction of CYP3A4 increases etonogestrel metabolism and lowers hormone levels.
