y son, 42 yrs, has schzophrenia. He has been prescribed Mirtazapine 300mg, diazepem 5 mg, serequil XR and was on aAdvancer slow elease (I think ). as well his psychiatrist gives him scriptsss for valium which he takes from time to time. Drug induced pyschosis and he says he never gets a full nights sleep, just wants to zonk out for some hours. Then I hear him say he had morph tablet last week. A tablet apparently. Should I just contact his psychiatrist as I m not the patien and don t know how to help.
