http://www.reuters.com/article/governmentFilingsNews/idUSN2427565220080124WASHINGTON, Jan 24 (Reuters) - Botox and a similar injection should come with stronger warnings following reports of 16 deaths after the botulinum toxin spread inside the body, a U.S. consumer group said on Thursday.
Public Citizen asked U.S. authorities to require the strongest possible warning, highlighted in a "black box," on Allergan Inc's (AGN.N: Quote, Profile, Research) Botox and Solstice Neuroscience Inc's Myobloc.
Botox is famous for smoothing facial wrinkles but also has approved medical uses such as treating cervical dystonia, or rigid neck muscles. Myobloc is cleared only for the neck condition.
Both injections are made with forms of the botulinum toxin, which blocks nerve impulses to muscles and makes them relax.
Public Citizen said it reviewed 180 reports submitted to the Food and Drug Administration by manufacturers involving patients injected with Botox or Myobloc. The reports detailed cases of muscle weakness, difficulty swallowing or aspiration pneumonia, a serious condition caused by breathing a foreign material into the lungs.
