Are there any medications that can help kids from stuttering?

Yes and no. It depends on the cause of stuttering. An evaluation by a speech/language pathologist and a developmental pediatrician should help chart a treatment course for a child with this problem.
Depends . The need or benefit from medication would depend on the cause of the stuttering along with what makes it worse. Medications are not usually a primary treatment for stuttering. However, if a high level of anxiety is present, medications may help to decrease stuttering by decreasing anxiety. Speech therapy would probably be the primary treatment.
