Dysport is an injection containing abobotulinumtoxinA (Botulinum toxin type A). AbobotulinumtoxinA is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity.

Dysport is used in adults to treat cervical dystonia (abnormal head position and neck pain).

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.

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 Dysport, even for cosmetic purposes.

You should not receive Dysport if you are allergic to botulinum toxin or cow's milk, or if you have an infection, swelling, or muscle weakness in the area where the medicine will be injected.

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. Some of these effects can occur up to several weeks after receiving a Dysport injection. This injection should be given only by a trained medical professional, even when used for cosmetic purposes. Botox is another brand of botulinum toxin injection. Do not seek botulinum toxin injections from more than one medical professional at a time. If you switch healthcare providers, be sure to tell your new provider how long it has been since your last botulinum toxin injection.

Before receiving Dysport injection, tell your doctor if you have ALS (Lou Gehrig's disease), myasthenia gravis, Lambert-Eaton syndrome, a breathing disorder, trouble swallowing, facial muscle weakness, a change in the appearance of your face, seizures, bleeding problems, heart disease, diabetes, if you have had or will have surgery, or if you have ever received other botulinum toxin injections such as Botox, Myobloc, or Xeomin.

The effects of abobotulinumtoxinA are temporary. Your symptoms may return completely within 3 months after an injection. After repeat injections, it may take less and less time before your symptoms return, especially if your body develops antibodies to the botulinum toxin.

Dysport injections should be given only by a trained medical professional, even when used for cosmetic purposes.

Dysport is injected into a muscle by a healthcare provider. The injections should be spaced at least 3 months apart. Children should not be treated with this medicine 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.

Tell your doctor if you are pregnant or breastfeeding.

Since botulinum toxin has a temporary effect and is given at widely spaced intervals, missing a dose is not likely to be harmful.

Tell your doctor about all your other medicines, especially:

• an injected antibiotic - amikacin, gentamicin, kanamycin, neomycin, paromomycin, streptomycin, tobramycin.

This list is not complete. Other medicines may interact with abobotulinumtoxinA, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here. Do not start a new medication without telling your doctor that you have received Dysport in the past.
