I was on dosages ranging from 2-4mg. Had major anxiety/panic attack reactions and the prolactin/lactation problems others have mentioned. Once we figured out the attacks were from the RIisperidone we dropped the dosage and I was on it for several more months. Of the APs and mood stabilizers I've taken this is the one I like best. Only went off because of a medical condition that had to be treated as a priority and those meds didn't play nice with this one.
