Generic Name: abobotulinumtoxinA (Dysport) (A boe BOT ue LYE num TOX in A)
Brand Name: Dysport

What is abobotulinumtoxinA (Dysport)?

AbobotulinumtoxinA (Dysport), also called botulinum toxin type A, 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 to treat cervical dystonia (severe spasms in the neck muscles).

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.

What is the most important information I should know about Dysport?

You should not receive this medicine 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.

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. Some of these effects can occur up to several weeks after a botulinum toxin injection.

What should I discuss with my healthcare provider before I receive Dysport?

You should not receive this medicine 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. Tell your doctor if you have ever had a side effect after receiving a botulinum toxin in the past

To make sure Dysport is safe for you, tell your doctor if you have:

  • amyotrophic lateral sclerosis (ALS, or "Lou Gehrig's disease");

  • myasthenia gravis;

  • Lambert-Eaton syndrome;

  • a breathing disorder such as asthma or emphysema;

  • 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;

  • bleeding problems;

  • heart disease;

  • diabetes;

  • if you have had or plan to have surgery (especially on your face); or

  • if you have ever received other botulinum toxin injections such as Botox or Myobloc (especially in the last 4 months).

Dysport is made from human plasma (part of the blood) which may contain viruses and other infectious agents. Donated plasma is tested and treated to reduce the risk of it containing infectious agents, but there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether Dysport passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How is Dysport given?

This medication is injected into a muscle. A doctor, nurse, or other healthcare provider will give you this injection. Botulinum toxin injections should be given only by a trained medical professional, even when used for cosmetic purposes.

Dysport injections should be spaced at least 3 months apart.

Your injection 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 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.

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.

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. Be careful if you drive or do anything that requires you to be able to see clearly.

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.

Call your doctor at once if you have any of these side effects, some of which can occur up to several weeks after an injection:

  • 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);

  • loss of bladder control;

  • crusting or drainage from your eyes;

  • severe skin rash or itching;

  • fast, slow, or uneven heartbeats; or

  • chest pain or heavy feeling, pain spreading to the arm or shoulder, general ill feeling.

Common side effects may include:

  • muscle weakness near where the medicine was injected;

  • bruising, bleeding, pain, redness, or swelling where the injection was given;

  • headache, muscle pain or stiffness, neck pain;

  • fever, cough, sore throat, runny or stuffy nose;

  • drooping eyelids, dry or puffy eyes;

  • nausea, dry mouth;

  • trouble swallowing; or

  • tired feeling.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

AbobotulinumtoxinA dosing information

Usual Adult Dose for Cervical Dystonia:

500 units IM given as a divided dose among affected muscles in patients with or without a history of prior treatment with botulinum toxin

Below is a description of the average dose, as well as the minimum and maximum dose injected into specific muscles in the pivotal clinical trials:
-Sternocleidomastoid: 125 Units (50, 350)
-Splenius capitis: 200 Units (75, 450)
-Trapezius: 102.6 Units (50, 300)
-Levator scapulae: 105.3 Units (50, 200)
-Semispinalis capitis: 131.6 Units (50, 250)
-Longissimus: 150 Units (100, 200)

-Limiting the dose injected into the sternocleidomastoid muscle may reduce the occurrence of dysphagia.
-Studies with this drug in cervical dystonia suggest that the peak effect occurs between 2 and 4 weeks after injection.
-Simultaneous EMG-guided application of this drug may be helpful in locating active muscles not identified by physical examination alone.
-Where dose modification is necessary for the treatment of cervical dystonia, studies suggest that dose adjustment can be made in 250 unit steps according to the individual patient's response, with retreatment every 12 weeks or longer, based on return of clinical symptoms. Studies also suggest that the total dose administered in a single treatment should be between 250 units and 1000 units.
-Retreatment, if needed, should not occur in intervals of less than 12 weeks.
-Doses above 1000 Units have not been evaluated.
-The starting dose of 500 units recommended for cervical dystonia is applicable to adults of all ages.

Use: For the treatment of adults with cervical dystonia

Usual Adult Dose for Glabellar Lines:

50 units divided into 5 equal aliquots of 10 units each, should be administered to affected muscles to achieve clinical effect

-The clinical effect of this drug may last up to 4 months.
-Repeat dose studies demonstrated continued efficacy with up to 4 repeated administrations.
-This drug should be administered no more frequently than every 3 months. -When used for re-treatment, this drug should be reconstituted and injected using the same techniques as the initial treatment.
