Resumo
Rifampicin is a strong enzyme inducer that substantially lowers hormonal contraceptive levels, risking contraceptive failure. With thalidomide, a pregnancy would carry a risk of severe birth defects.
O que esta interação significa em palavras simples
Rifampicin and Thalidomide 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.
Rifampicin belongs to Anti Bacterial; Thalidomide belongs to Miscellaneous.
Por que acontece
Induction of CYP3A4 and other enzymes by rifampicin increases contraceptive hormone metabolism.
