An intrauterine device for administering drug locally to the uterus at a controlled rate for a prolonged period of time is disclosed. The device contains a body of polymer capable of bioeroding in the environment of the uterus over a prolonged period of time. This body has the drug dispersed throughout so that as the body gradually bioerodes, it slowly releases the dispersed drug. In a preferred embodiment, the device releases a uterine contraction-inducing prostaglandin locally to the uterus at a controlled rate over a prolonged period of time.
