My son recently had an episode of Psychosis which was initiated by substance use. He is 20 years old. Doctor has prescribed Rosptril Plus 2 and Oliramp2. 5 mg at night. Is the prescription all right? And do we have to give him these different medicines or it can be managed by one drug only? He is much better now but but has become slow in his actions, is it the effect of these drugs? For how much time do I have give these drugs? I have read that these drugs are habit forming and once withdrawn they can cause much damage, is it true?
