Botox side effects cause heightened warnings
Monday, May 18th, 2009The drug used for cosmetic purposes and some muscle spasms known as Botox has received criticism for inadequate warnings about off-label uses.
The FDA-approved drug uses a toxin known as botulinium toxin type-A to remove facial wrinkles, relief of excessive sweating, and treatment for cervical dystonia and other facial muscle spasms. The toxin paralyzes the targeted muscles or nerves for an average three to four months.
If improperly used, the toxin (which is essentially the same bacterium that causes botulism) can spread throughout the body, causing muscle weakness, difficulty breathing, blurry vision, bladder control, and even death.
Another concern is the use of Botox to control muscle spasticity in children, including those with cerebral palsy. The FDA has not approved the use of Botox for that purpose; several injuries have been reported as a result of this off-label use.
