Prescription Dysport is an neurotoxin injection used to temporarily improve the look of moderate to severe frown lines between the eyebrows (glabellar lines) in adults less than 65 years of age.
Frequently Asked Questions
How does Dysport work?
With just 1 injection into each of 5 points between and over the eyebrows, Dysport stops the signal from the nerve to the muscles, ultimately resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines.
What is the most important information I should know about Dysport?
Dysport may cause serious side effects that can be life threatening. Call your doctor or get medical help right away if you have any of these problems after treatment with Dysport:
Problems swallowing, speaking, or breathing.
People with certain breathing problems may need to use muscles in their neck to help them breathe. These patients may be at greater risk for serious breathing problems with Dysport.
Swallowing problems may last for several weeks. 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 Dysport are at higher risk for these problems.
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
- Double-vision and blurred vision
- Drooping eyelids
- Hoarseness or change or loss of voice (dysphonia)
- Trouble saying words clearly (dysarthria)
- Loss of bladder control
- Trouble breathing and swallowing.
These symptoms can happen anywhere from hours to weeks after you receive an injection of Dysport.
Are there any reasons I should not be treated with Dysport?
Do not receive Dysport injections if you are allergic to Dysport or any of its ingredients (see the end of the Medication Guide for a list of ingredients), are allergic to cow’s milk protein, had an allergic reaction to any other botulinum toxin product (such as Myobloc® or Botox®), or have a skin infection at the planned injection site. Dysport should not be used in children or in women who are pregnant or breastfeeding.
If any of the following issues apply to you, we would advise not to receive Dysport:
- Previous facial surgery
- Weak muscles in the treatment area
- Inflamed injection site
- Droopy eyelids or sagging eyelid folds
- Deep facial scars
- Thick oily skin
- Wrinkles that cannot be smoothed by being spread apart
How often can I receive Dysport injections?
You should wait at least 90 days between Dysport treatments. The safety of Dysport has been studied in up to 12 repeated treatments. Clinical studies demonstrated continued efficacy with up to four repeated treatments.

Tell your doctor about all your medical conditions, including:
