On February 8, 2008, The U.S. Food and Drug Administration (FDA), the American equivalent of the Saudi Food and Drug Authority (SFDA), issued a warning based on reports of adverse reactions including respiratory compromise and death following the use of botulinum toxins approved and unapproved uses. The reactions occurs when botulinum toxin spreads in the body beyond the site where the drug was injected. The most serious cases had outcomes that included hospitalization and death, and occurred mostly in children treated for cerebral palsy associated limb spasticity.
