My 17yr old son had his first ever psychotic episode only 3 weeks ago, and this was definitely a substance induced (pot brownies of an enhanced kind) trigger that lead to loss of sleep, anxiety, then the episode. we had to admit him to hospital and after 2 weeks he is now stable and home but taking a total of 25mg olanzapine daily (5-5-15). It wipes him out, he s tired all day, and he s put on 10 lbs in only about a week (141lbs to 151lb). I think the dosage is too high, not sure but i d like to cut him back on the stuff. Can you tell me how long we might expect him to be on this dosage and how long it may take to taper him off the stuff? He s a student/athlete, but this med doesnt seem to allow him to do anything but eat and sleep. thanks
