[Chorea minor under ovulation inhibitors].

Three weeks after commencing oral contraception for the first time, a 26-year-old woman with a history of rheumatic carditis and chorea minor presented with sudden recurrence of hyperkinesis. Withdrawal of the contraceptive agent was followed by rapid remission of the hyperkinesis, which suggests a casual relationship between the contraceptive and this condition and an analogy between this case and so-called chorea gravidarum. A young non-pregnant woman presenting with chorea minor should be specifically questioned by ingestion of oral contraceptives. If there is a past history of rheumatic fever with or without chorea, oral contraceptives are contraindicated.
