Hi and Welcome!!!
What is his diagnosis? Why was he placed in the hospital? How long was he in? What is his doseage?
Medicating is very scary- our first medication was Risperdal. It was great in the beginning, but for our daughter it was not the best Atypical Antipsychotic. a lot of times depending on what his diagnosis is, is you will combine an AP with a Mood Stabilizer...
My difficult child is on Abilify and Lamictal...
Mood Stabilizers like: Lithium, Depakote, Tegretol. Those are the big 3.
What are his symptoms that they are trying to treat with the Risperdal?
K was on it for mania, violence, auditory hallucinations, aggitation- her extreme high end reactions.
She ended up having drooling, toungue thrust, mouth hanging open, increase agitation,involuntary movements (Tardive Dyskinesia) But a lot of AP's can do this... we found with K we have to start very low and go very slow with her increases.
Hope this helps a bit .
good luck
