Mirapex is for the treatment of Parkinson's and Restless Leg Syndrome. One of the nasty side effects of the medication is poor impulse control. Patients or their family members report an increase in compulsive gambling, hyper sexuality and more. Patients even tend to eat out of control. Fortunately, if the medication is stopped, because of the negative side effects, the behavior soon returns to normal. But, patients also report the inability to stay awake. Due to the medication, some people can actually fall asleep right in the middle of a conversation. Elderly patients are also more susceptible to the positive and negative effects of the medication.
