Oral medications provide little relief from the symptoms of spasmodic dysphonia. However, if other forms of dystonia are present, medications may help relieve those related symptoms. At this time, no medication is specifically indicated to treat a dystonia; however, a number of products, including Sinemet® (carbidopa/levodopa), Ativan® (lorazepam), Klonopin® (clonazepam), Neurontin® (gabapentin), and Valium® (diazepam), are used to settle muscles or nerves with excess activity. Other categories of medications used in the treatment of dystonia include anticholinergics, benzodiazepines, and baclofen.
Some patients have reported a benefit from these, but often this can be at the expense of common side effects such as drowsiness or nausea.
