Yes there are medication,but should only be taken under supervision of a doctor (psychiatrist). medication like resperidone, ziprasidone,saphris,ability,and most effective them of called as olanzapine but it has a weight gain side effect.But the problem is that some will react to this medication some will not.so it's like a hit and trial method where you need a lot of patience.cause it's not so easy but it's entirely possible.so best of luck and don't lose hope
