What is PrabotulinumtoxinA-xvfs?[edit | edit source]

PrabotulinumtoxinA-xvfs (JEUVEAU) is an acetylcholine release inhibitor and a neuromuscular blocking agent.

What are the uses of this medicine?[edit | edit source]

This medicine is injected into muscles and used in adults for a short period of time (temporary) to improve the look of moderate to severe frown lines between the eyebrows (glabellar lines).

How does this medicine work?[edit | edit source]

  • JEUVEAU blocks neuromuscular transmission by binding to acceptor sites on motor nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine.
  • This inhibition occurs as the neurotoxin cleaves SNAP-25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within nerve endings.
  • When injected intramuscularly at therapeutic doses, JEUVEAU produces partial chemical denervation of the muscle resulting in a localized reduction in muscle activity.
  • In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop.
  • There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by JEUVEAU.

  • JEUVEAU may cause loss of strength or general muscle weakness, vision problems, or dizziness within hours to weeks of receiving JEUVEAU. If this happens, do not drive a car, operate machinery, or do other dangerous activities.


What to do in case of emergency/overdose?[edit | edit source]

  • Excessive doses of JEUVEAU (prabotulinumtoxinA-xvfs) injection may be expected to produce neuromuscular weakness with a variety of symptoms.
  • Symptoms of overdose are likely not to be present immediately following injection.
  • Should accidental injection or oral ingestion occur, or overdose be suspected, these patients should be considered for further medical evaluation and appropriate medical therapy immediately instituted, which may include hospitalization.
  • The person should be medically supervised for several weeks for signs and symptoms of systemic muscular weakness which could be local or distant from the site of injection.
  • If the musculature of the oropharynx and esophagus are affected, aspiration may occur which may lead to development of aspiration pneumonia.
  • If the respiratory muscles become paralyzed or sufficiently weakened, intubation and assisted respiration may be necessary until recovery takes place. Supportive care could involve the need for a tracheostomy and/or prolonged mechanical ventilation, in addition to other general supportive care.

Management for overdosage

  • In the event of overdose, antitoxin raised against botulinum toxin is available from the Centers for Disease Control and Prevention (CDC) in Atlanta, GA. However, the antitoxin will not reverse any botulinum toxin-induced effects already apparent by the time of antitoxin administration.
  • If you do not receive a response within 30 minutes, please contact the CDC directly at 1-770-488-7100.
