Hello, my son Max 19yrs old non-verbal autistic man is taking Naltrexone started with 50 mg and innow increased to 200 mg advice by his psychaitrist to treat agression behavior . It was working quite well during lower doses. Now, he developed agression behavior like hit the wall and left hole, very confusing, emotional/upset easily without reasons, problem sleep, look depress, nausea and vomiting,press cough, tiredness , lost interest of any kind of activity, requested more sleep...I try to contact his psychaitrist but he 's away...my question : should I reduce the doses ? Thanks for advance
