Safety + Side Effects + Authentic Dysport®
Identifying authentic Dysport
There’s only one FDA-approved Dysport. It’s important to find a primary care physician, dermatologist, cosmetic aesthetician, plastic surgeon or other healthcare professional who is trained and licensed to administer Dysport.
Galderma provides comprehensive training for all qualified healthcare providers who want to inject our aesthetic products. Be sure to ask your specialist to see the packaging of your product to make sure it’s authentic.
There are more anti-counterfeiting measures on the packaging that aren’t listed here. Ask your specialist to verify the Dysport you’re being treated with is authentic.

Common side effects
When it comes to possible side effects, you may be wondering why Dysport has a boxed warning. In 2009, following a comprehensive safety review, the FDA mandated that all botulinum toxins—including Dysport—carry a boxed warning to bring attention to the fact that these products have the potential to spread from the injection site to other parts of the body, resulting in serious life-threatening risks, including difficulty talking, swallowing or breathing; muscle weakness; drooping eyelids; and blurred or double vision.
However, the most common possible side effects include:
- nose and throat irritation
- injection site pain
- injection site skin reaction
- upper respiratory tract infection
- eyelid swelling
- eyelid drooping
- sinus inflammation
Other side effects
Dysport may cause serious side effects that can be life threatening, including:
Problems breathing or swallowing — People who already have swallowing or breathing problems before receiving Dysport have the highest risk of getting these problems. These problems can happen within hours, or days to weeks after an injection of Dysport, usually because the muscles used to breathe and swallow can become weak after the injection. Death can happen as a complication if you have severe problems with swallowing or breathing after treatment with Dysport.
- 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 can not 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.
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
- double vision
- blurred vision and drooping eyelids
- hoarseness or change or loss of voice (dysphonia)
- trouble saying words clearly (dysarthria)
- loss of bladder control
- trouble breathing
- trouble swallowing
