Chorea associated with oral contraception.
Three patients developed chorea while receiving oral contraceptives. Two were young patients whose chorea developed long after treatment had been started and disappeared soon after it had been discontinued. The third patient had acute amphetamine-induced chorea after prolonged oral contraception. Prolonged administration of female sex hormones is a possible cause of chorea in women who have not previously had chorea or rheumatic fever.
