Daxxify

Generic name: daxibotulinumtoxinA-lanm

What is Daxxify?

Daxxify is a prescription medicine for adults that is injected into muscles to temporarily improve the look of moderate to severe frown lines between the eyebrows (glabellar lines).
It is not known if Daxxify is safe and effective in children less than 18 years of age.

What is the most important information I should know about Daxxify?

Daxxify may cause serious side effects that can be life threatening. Call your healthcare provider or get medical help right away if you have any of these problems after treatment with Daxxify:

  • Problems swallowing, speaking, or breathing. These problems can happen hours, days, or weeks after an injection of Daxxify if the muscles that you use to breathe and swallow become weak after the injection. Death can happen as a complication if you have severe problems with swallowing or breathing after treatment with Daxxify.
    • People with certain breathing problems may need to use muscles in their neck to help them breathe. These people may be at greater risk for serious breathing problems with Daxxify.
    • Swallowing problems may last for several months. People who cannot swallow well may need a feeding tube to receive food and water. If swallowing problems are severe, food or liquids may go into your lungs. People who already have swallowing or breathing problems before receiving Daxxify have the highest risk of getting these problems.
  • Spread of toxin effects. In some cases, the effect of botulinum toxin may affect areas of the body away from the injection site and cause symptoms of a serious condition called botulism. The symptoms of botulism include:
    • loss of strength and muscle weakness all over the body
    • blurred vision and drooping eyelids
    • trouble saying words clearly
    • trouble breathing
    • double vision
    • hoarseness or change or loss of voice
    • loss of bladder control
    • trouble swallowing

These symptoms can happen hours, days, or weeks after you receive an injection of Daxxify.
These problems could make it unsafe for you to drive a car or do other dangerous activities. See "What should I avoid while using Daxxify?"
Although no serious adverse reactions of distant spread of toxin effect associated with Daxxify have been reported in clinical studies of 40 Units for glabellar lines, these reactions are possible.
