A word of warning to those who’d want to keep their skin wrinkle-free. Popular anti-wrinkle drug, Botox is now being flagged by the US FDA for its possible side effects. While Botox has been used to treat wrinkles, it is also used to treat muscle spasms in children. And there have been fatality cases in some children on whom the drug was administered. CNN reports:

The Food and Drug Administration’s warning includes both Botox, a wrinkle-specific version called Botox Cosmetic, and its competitor, Myobloc, drugs that all use botulinum toxin to block nerve impulses, causing them to relax.

In rare cases, the toxin can spread beyond the injection site to other parts of the body, paralyzing or weakening the muscles used for breathing and swallowing, a potentially fatal side effect, the FDA said.
