Aripirazole (the one i take, most common i think), Olanzapine, Risperidone. These are anti psychotics. Some ssris can help too Also there is one medication (Ecopipam) that is coming out for stuttering but its still in trails. Hopefully by next year Man they have been talking about Ecopipam since I was a kid -_- It can be a big decision to get on these type of medications be sure to talk it through with your doctor. But its been helping me, I still stutter but im still in the beginning and on a small dose
