Dysport Warnings and Precautions

If you are allergic to cow's milk protein, you should avoid the prescription drug Dysport. Warnings and precautions also extend to people with certain neuromuscular conditions, such as amyotrophic lateral syndrome. Women who are pregnant or breastfeeding should talk to their healthcare providers before starting treatment with this medication.

What Should I Tell My Healthcare Provider Before Receiving Dysport?

Before beginning treatment with Dysport® (abobotulinumtoxinA), you should talk with your healthcare provider if you have:
  • An infection near the site where you would receive the injections
  • Difficulty swallowing
  • An allergy to cow's milk protein
  • Neuromuscular disease, such as:
Also, let your healthcare provider know if you are:
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
In addition, tell your healthcare provider about all of the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Specific Precautions and Warnings With Dysport

Warnings and precautions to be aware of prior to receiving Dysport injections include the following:
  • In rare cases, Dysport can spread from the site of injection to distant parts of the body, potentially causing serious problems. This is most likely to occur if the drug is used to treat spasticity in children. It should be noted that Dysport is not approved for use in children.
  • The recommended Dysport dosage is different from the recommended Botox® dosage, even though both medications contain botulinum toxin type A. The dose of Dysport cannot be compared or converted to a Botox dosage.
  • The medication can cause allergic reactions. If you notice an unexplained rash, itching, wheezing, swelling, or difficulty breathing, tell your healthcare provider right away.
  • Dysport can cause difficulty swallowing, which may cause serious problems. This is more likely if you already have swallowing problems or if you have a neuromuscular disease.
  • Dysport contains albumin, a human protein. Theoretically, viruses or infectious proteins may be transmitted through albumin. However, this has never been reported with an albumin product.
  • Sometimes, the medication can decrease your blinking reflex, especially if it is used near the eyes. This can dry out your eyes, increasing your risk of corneal abrasion or other eye problems. If your eyes seem to be dry, let your healthcare provider know right away.
  • Sometimes, Dysport injections in the area near the eyes can cause vision changes. These changes are usually temporary.
  • Dysport can interact with a few different medications (see Dysport Drug Interactions).
  • Dysport is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known (see Dysport and Pregnancy).
  • It is not known if Dysport passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Dysport and Breastfeeding).
