acitretin and Ethanol Interactions

Interactions between acitretin and Ethanol (ethanol)

ethanol and acitretin (Major Drug-Drug)

CONTRAINDICATED: Ethanol consumption with acitretin leads to the formation of etretinate, which has a much longer half-life than acitretin. Major human fetal abnormalities have been associated with the administration of acitretin, etretinate, and other retinoids. The longer elimination half-life of etretinate relative to acitretin increases the duration of teratogenic potential for female patients. In one case report of a patient with apparent sporadic ethanol intake, etretinate was present in plasma and fat for 52 months after acitretin was discontinued.

MANAGEMENT: Female patients should be warned that ethanol is contraindicated during active treatment with acitretin and for two months after cessation of therapy.
