Oral contraceptive induced paraballism.
We report a case of paraballism in a young female, which became apparent 4 months after initiating oral contraception. When the oral contraceptive was discontinued, the paraballism decreased and was replaced by choreic movements for a period of approximately 2 weeks. The abnormal movements disappeared gradually. Only 13 cases of paraballism have been reported in medical literature, and none has been attributed to the use of oral contraceptives.
