What is abobotulinumtoxinA (Dysport)?
Dysport is also used to treat muscle spasms and stiffness (spasticity) of the arms, hands, legs, and feet in adults and children at least 2 years old. This medicine will not treat spasticity caused by cerebral palsy.
Dysport is also used to temporarily lessen the appearance of facial wrinkles.
Dysport may also be used for purposes not listed in this medication guide.
The botulinum toxin contained in Dysport can spread to other body areas beyond where it was injected. This can cause serious life-threatening side effects.
Call your doctor at once if you have a hoarse voice, drooping eyelids, vision problems, severe muscle weakness, loss of bladder control, or trouble breathing, talking, or swallowing.
Before taking this medicine
You should not receive this medicine if you are allergic to botulinum toxin or cow's milk, or if you have an infection in the area where the medicine will be injected. Tell your doctor if you have ever had a side effect after receiving botulinum toxin in the past.
Tell your doctor if you have ever had:
amyotrophic lateral sclerosis (ALS, or "Lou Gehrig's disease");
problems with swallowing;
facial muscle weakness (droopy eyelids, weak forehead, trouble raising your eyebrows);
a change in the normal appearance of your face;
a seizure disorder;
a heart rhythm disorder;
dry eyes after after receiving botulinum toxin in the past;
a recent or planned surgery (especially on your face); or
Dysport is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.
Tell your doctor if you are pregnant or breastfeeding.
How is Dysport given?
Dysport injections should be given only by a trained medical professional, even when used for cosmetic purposes.
This medicine is injected into a muscle by a healthcare provider. Dysport injections should be spaced at least 3 months apart. Children should not be treated with Dysport more often than every 12 to 16 weeks.
Dysport injections may be given into more than one area at a time, depending on the condition being treated.
The effects of a Dysport injection are temporary. Your symptoms may return completely within 3 months. After repeat injections, it may take less and less time before your symptoms return, especially if your body develops antibodies to the botulinum toxin.
Do not seek botulinum toxin injections from more than one medical professional at a time. If you switch healthcare providers, tell your new provider how long it has been since your last botulinum toxin injection.
Using this medicine more often than prescribed will not make it more effective and may result in serious side effects.
What happens if I miss a dose?
Since botulinum toxin has a temporary effect and is given at widely spaced intervals, missing a dose is not likely to be harmful.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may not appear right away, but can include muscle weakness, trouble swallowing, and weak or shallow breathing.
What should I avoid after receiving Dysport?
Dysport may impair your vision or depth perception. Avoid driving or hazardous activity until you know how this medicine will affect you.
Avoid going back to your normal physical activities too quickly after receiving an injection.
Dysport side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; feeling like you might pass out; swelling of your face, lips, tongue, or throat.
The botulinum toxin contained in Dysport can spread to other body areas beyond where it was injected. This has caused serious life-threatening side effects in some people receiving botulinum toxin injections, even for cosmetic purposes.

trouble breathing, talking, or swallowing;
hoarse voice, drooping eyelids;
problems with vision;
unusual or severe muscle weakness (especially in a body area that was not injected with the medication);
