Botulinum Toxin Type A works by blocking neural impulses to the muscles in the injected area. As a result, the muscles relax and muscle spasms — sudden, involuntary contractions of the muscles — are no longer able to occur.
Anyone who suffers from severe, chronic muscle spasms may be an ideal candidate for treatment with BOTULINUM TOXIN ® . Candidates though must be realistic in their expectations. Though BOTULINUM TOXIN ® injections are effective in treating muscle spasms in many patients, results do vary among those treated.
