Use of quinine for self-induced abortion

We present four recent cases in which quinine was used for self-induced abortion. Abortion was achieved in only one of these cases. Literature review suggests that quinine is an ineffective abortifacient, even when taken in toxic doses. Adverse effects of quinine include cinchonism, potentially fatal renal failure, and possible teratogenesis. Quinine is available over-the-counter, but it has few legitimate medical indications. Health care personnel treating women with undesired pregnancies should be alert to the signs and symptoms of quinine toxicity.
