We report two women using oral contraceptives, aged 17 and 33 years old, who presented with hemichorea. In both patients all other possible causes of chorea were discarded and the disease disappeared when contraceptives were discontinued. Four months later, the 33 years old patient used again oral contraceptives and chorea reappeared. This rare complication of contraceptive use has been previously reported in young and mainly nulliparous women.
