Some of the Mirapex side effects are strange. Therefore, it is important for you to know the risks, as well as the benefits, before you start taking this medication. For instance, patients and their families report a personality change. Under the influence of Mirapex, users may tend to be more compulsive and taking unnecessary chances. Some may go on a gambling spree; others might experience hyperactive sexuality, and even compulsive eating. Fortunately, patients quickly return to normal, once weaned off the medication. Nevertheless, it is important not to simply quit taking your doses. Consult the doctor first. Also, be careful about driving. Patients have been known to fall asleep right in the middle of a conversation.
