Brand Name(s): Jeuveau^®

IMPORTANT WARNING:

PrabotulinumtoxinA-xvfs injection may spread from the area of injection and cause symptoms of botulism, including severe or life-threatening difficulty breathing or swallowing. People who develop difficulty swallowing during their treatment with this medication may continue to have this difficulty for several months. They may need to be fed through a feeding tube to avoid getting food or drink into their lungs. Tell your doctor if you have or have ever had swallowing problems, or breathing problems, such as asthma or emphysema; or any condition that affects muscles or nerves such as amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease; condition in which the nerves that control muscle movement slowly die, causing the muscles to shrink and weaken), myasthenia gravis (condition that causes certain muscles to weaken, especially after activity), or Lambert-Eaton syndrome (condition that causes muscle weakness that may improve with activity).

Spread of prabotulinumtoxinA-xvfs into untreated areas can cause other symptoms in addition to difficulty breathing or swallowing. Symptoms may occur within hours of an injection or as late as several weeks after treatment. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: loss of strength or muscle weakness all over the body; double or blurred vision; drooping eyelids or brow; difficulty swallowing or breathing; or difficulty speaking or saying words clearly.
