Safety Alerts & Recalls
What does this mean?
The new boxed warning emphasizes the importance of recognizing the rare but serious side effects of BOTULINUM TOXIN TYPE B (MYOBLOC), including unexpected loss of strength or muscle weakness, hoarseness or trouble talking (dysphonia), trouble saying words clearly (dysarthria), loss of bladder control, trouble breathing, trouble swallowing, double vision, blurred vision and drooping eyelids. These adverse events have been reported as early as several hours and as late as several weeks after treatment. If you are receiving treatment with BOTULINUM TOXIN TYPE B (MYOBLOC) please seek immediate medical attention if you develop any of these symptoms.
New Boxed Warning
In a follow up to the safety review conducted in early 2008, the FDA is requiring manufacturers to change the labeling for botulinum products, including BOTULINUM TOXIN TYPE B (MYOBLOC), to include a boxed warning about the risk of adverse events when the effects of the toxin spread beyond the injection site.
