What is Dysport
Dysport is a muscle relaxant produced by Clostridium botulinum bacteria. It acts on the junctions between the nerves and muscles, preventing the release of one of the chemical messengers called acetylcholine from the nerve endings that would normally cause the muscle to contract. If the messenger is prevented from being released this results in a weakened muscle and helps to reduce some of the abnormal muscle contractions.
What Dysport is used for
Dysport is used for the treatment of
upper limb spasticity in adults. Upper limb spasticity is an increased stiffness in the arm and/or hand muscles that develops in many patients after a stroke, for example, and can lead to restricted use of the arm or hand.
lower limb spasticity in adults. Lower limb spasticity is an increased stiffness in the leg and/or foot muscles that develops in many patients after a stroke, for example, and can lead to restricted use of the leg or foot.
spasmodic torticollis in adults. Spasmodic torticollis is where there is a turning movement of the neck leading to an unusual head and shoulder position
lower limb spasticity in children (2 years of age and older) which may be due to cerebral palsy. Cerebral palsy spasticity is a disorder in which some muscles become stiff and movement is difficult
blepharospasm or hemifacial spasm in adults. Blepharospasm is a condition affecting the eye lid muscles causing uncontrollable blinking and closure of the eyelids. Hemifacial spasm is a condition that causes the muscles on one side of the face to contract without control from the person affected
moderate to severe glabellar lines which are the vertical frown lines which may appear between your eyebrows
moderate to severe lateral canthal lines (also known as 'crow's feet' lines) which are the lines that may appear near the outside corner of your eyes
Your doctor may have prescribed it for another reason. Ask your doctor if you have any questions why Dysport has been prescribed for you.
Before you are given Dysport
You must not be given Dysport if
you have had a previous allergic reaction to botulinum toxin or any of the ingredients listed at the end of this leaflet
you have a medical condition called myasthenia gravis or a myasthenic syndrome
if there is any sign of infection at the proposed injection site
the package is damaged or shows signs of tampering, or if the product does not look quite right
Before you are given Dysport
Tell your doctor if you have:
any difficulties in swallowing
a history of bronchitis, pneumonia and problems with your breathing
an allergy to any of the ingredients contained in Dysport that are listed at the end of this leaflet
any reactions such as skin rash or 'flu-like' symptoms to any injections of toxin in the past
worsening or changes in your muscle spasms
previous prolonged periods of muscle weakness
a history of prolonged bleeding times
inflammation at the proposed injection site
ever had facial surgery
been given Dysport or another brand of botulinum toxin in the past few weeks
received any facial cosmetic procedures recently, particularly if Dysport will be injected into your facial muscles
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without prescription from your pharmacy, supermarket or health food shop.
Some medicines can interfere with the way Dysport works such as
muscle relaxants
aminoglycoside antibiotics
penicillamine, procainamide, spectinomycin, polymixins, tetracyclines and lincomycin
These drugs must be used with caution if you are receiving Dysport. Your doctor will advise you accordingly.
Dysport contains a small amount of albumin that has been obtained from human blood. The risk of a viral infection cannot be eliminated completely when using human blood or products made from human blood.
Use in Children
Dysport can be used for the treatment of lower limb spasticity in children (2 years of age and older). It is not recommended for children under 2 years of age. Dysport should not be used for treatment of any other conditions in children.
Use in Elderly
A reduced dose may be appropriate in elderly patients where reduced muscle mass may exist.
Use in Pregnancy and Lactation
Tell your doctor if you are pregnant or intend to become pregnant, or if you are breastfeeding or plan to start breastfeeding.
Your doctor will advise you regarding the use of Dysport in pregnancy.
Use of Dysport during breastfeeding is not recommended.
Effect on ability to drive and use machines
Local weakness can be expected and there is a possibility of unexpected side effects such as generalised weakness. These effects can affect the ability to drive and use machines.
How Dysport is given
How to use it
Your doctor will make up and give you the injection. For the injection, Dysport will be dissolved in 0.9% sodium chloride injection. Dysport is given as an injection in the muscle (intramuscularly), or under the skin (subcutaneously) after dilution, depending on the condition for which you are being treated.
Your doctor will decide where to make the injections and for how long you need treatment. You will be given injections of your medicine in a clinic that specialises in treating your condition. The doctor who injects your medicine will have received training and be experienced in giving Dysport injections.
How much is given
If you are being treated for upper limb spasticity, your first dose of Dysport can be up to 1000 units in total depending on the size, number and location of muscles involved. The doctor will give a number of injections into the affected muscles in your arm or hand. Injections will be given approximately every 12 to 16 weeks, or as required to maintain the response, but not more frequently than every 12 weeks. The maximum recommended dose is 1000 units. Doses greater than 1000 units and up to 1500 units, when the shoulder muscles were also injected, have been used in clinical trials but have not been adequately studied.
If you are being treated for lower limb spasticity, your first dose of Dysport can be up to 1500 units in total depending on the size, number and location of muscles involved, how severe the spasticity is, and taking into account any local muscle weakness and your previous response to treatment. The doctor will give a number of injections into the affected muscles in your leg or foot. Injections will be given approximately every 12 to 16 weeks, or as required to maintain the response, but not more frequently than every 12 weeks. The maximum dose must not exceed 1500 units.
If you have spasmodic torticollis, your first dose of Dysport will be 250 - 500 units in total. Your doctor will give injections into a number of places in your neck, probably into the 2 or 3 of the neck muscles most affected by the condition. Your doctor will decide how much to give and which muscles to inject. Injections will be given approximately every 16 weeks, or as required to maintain the response, but not more frequently than every 12 weeks. The maximum dose must not exceed 1000 units.
If you are being treated for paediatric lower limb spasticity, the first and subsequent dose will be dependent on the size, number and location of muscles involved, how severe the spasticity is, and taking into account any local muscle weakness, your previous response to treatment and/or adverse event history with botulinum toxins. When possible, the dose will be distributed across more than 1 injection site in any single muscle. The maximum dose must not exceed 30 units /kg or 1000 units whichever is lower. Injections will be given approximately every 16-22 weeks, or as required to maintain the response, but not more frequently than every 12 weeks.
If you are being treated for blepharospasm affecting both eyes, your first dose will be approximately 40 units of Dysport per eye. The medicine will be injected just under the skin at certain sites around the eye. These sites and the exact amount needed will be decided by the doctor. Injections will be given approximately every twelve weeks when the relaxing effect on the muscles is wearing off, but not more frequently than every 12 weeks. On the next visits the amount of Dysport given may be increased to 60, 80 or 120 units per eye if a longer duration of effect is required. The doctor will decide what dose to administer. If only one eye is affected by blepharospasm, the doctor will only give injections of Dysport around this eye.
If you are being treated for hemifacial spasm the doctor will give injections as for blepharospasm but on the affected side of your face only.
If you are being treated for glabellar lines, the recommended dose of Dysport is 50 units to be divided equally among 5 injection sites. The effect of the treatment may last for 4 to 5 months. There should be a minimum interval of 12 weeks between treatments.
If you are being treated for lateral canthal lines, the recommended dose of Dysport is 30 units per side to be divided equally among 3 injection sites (60 units total at 6 injection sites). The treatment interval depends on the individual patient's response after assessment but should not be more frequent than every three months.
Your doctor will decide when you will need your next injection and how much of the medicine will be injected.
If you miss an injection
Nothing will happen if you miss a scheduled appointment for your injection other than some of the spasm or muscle stiffness may return. Consult your doctor and they will decide when you need your next injection.
If you stop getting injections
The relaxing effect will eventually wear off and the muscle movements will return to the way they were before treatment.
If you are given too much medicine (overdose)
As it is given to you by your doctor who has received training on administration of Dysport, it is very unlikely that you will receive an overdose. However, if you are given too much Dysport, there is an increased risk of the medicine getting into the bloodstream and causing complications associated with oral botulinum poisoning. Paralysis of your muscles may occur and you may be placed on a respirator and other support systems if it affects your breathing. Contact the Poisons Information centre on 131126 if you believe you may have been given too much Dysport.
