my son took risperdal for 6 years with out any noticeable side effects, it is supposed to cause nerve damage if used for long periods of time. It was the best thing that ever happened for my son, it really helped control his meltdowns, he rarely has them now and he's off of the drug. he only takes celexa now. He was on paxil also at the time of the risperdal. it did stablize his moods too. I think you should weigh the pros and cons, If you want to control moods and meltdowns I'd try it for a while, the damage with this drug is from longterm use. My son is only on 1 drug now, he used the antipsychotic to help him through some very rough years, now all he treats is the anxiety.
