I started giving risperidone to my son in January 2008 because his violent fits had become uncontrollable so that I had to quit my job to look after him. It worked, lessened his 'tantrums', and I was able to work again. He has been taking 1mg doses everyday up to the present. But lately he has become very irritable again, hitting his stomach and banging his head like before. I am wondering if the drug is doing this to him, or if the dosage is no longer enough. Is risperidone addictive? I don't want him to get dependent on the drug, but I don't know if I really have a choice.
