What is Jeuveau?

Jeuveau is a prescription medicine that 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).

It is not known if Jeuveau is safe and effective for use in children.


PrabotulinumtoxinA-xvfs is an acetylcholine release inhibitor and a neuromuscular blocking agent. PrabotulinumtoxinA-xvfs is supplied as a sterile, vacuum-dried powder in a single-dose vial intended for intramuscular use after reconstitution. PrabotulinumtoxinA-xvfs is a 900 kDa botulinum toxin type A, produced from fermentation of Clostridium botulinum.

The primary release procedure for JEUVEAU uses an animal based potency assay to determine the potency relative to a reference standard. The assay is specific to Evolus’ product, JEUVEAU. One Unit of JEUVEAU corresponds to the calculated median intraperitoneal lethal dose (LD50) in mice. Due to specific details of this assay, Units of biological activity of JEUVEAU cannot be converted into Units of any other botulinum toxin or any toxin assessed with any other specific assay method.

Each vial of JEUVEAU (prabotulinumtoxinA-xvfs) for injection contains 100 Units of botulinum toxin type A neurotoxin complex, human serum albumin (0.5 mg), and sodium chloride (0.9 mg) in a sterile, vacuum-dried form without a preservative.

Mechanism of Action

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.

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

Jeuveau 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 Jeuveau:

  • Problems swallowing, speaking, or breathing. These problems can happen hours, days, or weeks after an injection of Jeuveau 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 Jeuveau.
    • 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 Jeuveau.
    • 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 Jeuveau 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 Jeuveau.

These problems could make it unsafe for you to drive a car or do other dangerous activities. See “What should I avoid while using Jeuveau?”

Who should not use Jeuveau?

Do not receive Jeuveau if you:

  • are allergic to Jeuveau or any of the ingredients in Jeuveau. See the end of the Medication Guide for a list of ingredients in Jeuveau.
  • had an allergic reaction to any other botulinum toxin product such as rimabotulinumtoxinB (Myobloc), onabotulinumtoxinA (Botox, Botox Cosmetic), abobotulinumtoxinA (Dysport), or incobotulinumtoxinA (Xeomin).
  • have a skin infection at the planned injection site.

What should I tell my healthcare provider before using Jeuveau?

Before receiving Jeuveau, tell your healthcare provider about all your medical conditions, including if you:

  • have a disease that affects your muscles and nerves (such as amyotrophic lateral sclerosis [ALS or Lou Gehrig’s disease], Myasthenia gravis or Lambert-Easton syndrome). See “What is the most important information I should know about Jeuveau?”
  • had any side effect from any botulinum toxin product in the past
  • have or have had a breathing problem, such as asthma or emphysema

  • have had dry eye with use of botulinum toxin products in the past
  • are pregnant or plan to become pregnant. It is not known if Jeuveau can harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if Jeuveau passes into breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with Jeuveau.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements.

Using Jeuveau with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your healthcare provider that you have received Jeuveau in the past.

Especially tell your healthcare provider if you:

  • have received any other botulinum toxin product in the last 4 months
  • have received injections of botulinum toxin, such as onabotulinumtoxinA (Botox, Botox Cosmetic) rimabotulinumtoxinB (Myobloc), abobotulinumtoxinA (Dysport) or incobotulinumtoxinA (Xeomin). Be sure your healthcare provider knows exactly which product you received.

Know the medicines you take. Keep a list of your medicines with you to show your healthcare provider and pharmacist each time you get a new medicine.
