Botox Deaths
Botox is best known for minimizing wrinkles by paralyzing facial muscles -- but botulinum toxin also is widely used for a variety of muscle-spasm conditions, such as cervical dystonia or severe neck spasms.
The FDA said the deaths it is investigating so far all involve children, mostly cerebral palsy patients being treated for spasticity in their legs. The FDA has never formally approved that use for the drugs, but some other countries have.
However, the FDA warned that it also is probing reports of illnesses in people of all ages who used the drugs for a variety of conditions, including at least one hospitalization of a woman given Botox for forehead wrinkles.
