FDA is alerting health care professionals and consumers that unsafe counterfeit versions of Botox (botulinum toxin) have been found in multiple states and administered to consumers for cosmetic purposes.

FDA is aware of adverse events, including hospitalizations, linked to the counterfeit Botox. Symptoms included blurred or double vision, difficulty swallowing, dry mouth, constipation, incontinence, shortness of breath, weakness and difficulty lifting one’s head following injection of these products. These symptoms are similar to those seen when botulinum toxin spreads to other parts of the body.
