My Son Is Autistic, Nonverbal, 14 Yrs Old. He Has

My son is autistic, nonverbal, 14 yrs old. He has slept over 15 per day for the last 2 days. He has no fever, no med changes. I cant keep him awake. I checked the pharmacy to see if the generics for Risperdone and Lexapro were not given correctly and they ruled that out. He doesn't seem distressed but can't stay awake. He has had constipation issues but think that is secondary.
