Results may vary. In December the FDA approved Botox for treating cervical dystonia, a disorder that causes severe neck and shoulder muscle contractions. The FDA approval was based on placebo-controlled, randomized clinical trials involving a total of patients with moderate to severe glabellar lines who were treated with Botox. The improvement lasted up to days.

The FDA recommended that Botox be used no more than once every 3 months. Botox injections are the fastest growing cosmetic treatment provided by surgeons in the United States, according to Roberta D. Sengelmann, MD, a Washington University dermatologist and otolaryngologist who was quoted in Allergan's news release. Allergan officials said Botox therapy is used in 70 countries and is being investigated in the United States as a possible treatment for excessive sweating, post-stroke spasticity, back spasms, and headache.
