CONSUMER MEDICINE INFORMATION

What is in this leaflet

This leaflet answers some common questions about Dysport. It does not contain all
of the available information. It does not take the place of talking to your doctor
or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking
Dysport against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.

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

upper and 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 or 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

you bleed easily or have a history of prolonged bleeding times

inflammation or infection 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 upper and 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 treatment is required in both the upper and lower limbs during the same treatment
session, the dose of Dysport to be injected in each limb will be tailored to your
needs, without exceeding a total body dose of 1500U.

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 your child is being treated for upper or 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, the 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.

For lower limb spasticity in children, the maximum dose must not exceed 30 units /kg
or 1000 units whichever is lower. Your child’s doctor will repeat the treatment approximately
every 16-22 weeks, or as required to maintain the response, but not more frequently
than every 12 weeks.

For upper limb spasticity in children, if the treatment is injected into one arm,
the dose must not be higher than 640 units or 16 units/kg at a given treatment session,
whichever is lower. If the treatment is injected into both arms, the dose must not
be higher than 840 units or 21 units/kg at a given treatment session, whichever is
lower. Your child’s muscle spasms should normally improve in the weeks following treatment
and this improvement may last up to 34 weeks. Your child’s doctor will repeat the
treatment approximately every 16 – 28 weeks or as needed, but no more frequently than
every 16 weeks.

For treatment of both upper and lower limb spasticity in of children during the same
treatment session, the dose of Dysport to be injected in each limb should be decided
by your child’s doctor, without exceeding a total body dose per treatment session
of 1000 units or 30 units/kg, whichever is lower. Retreatment of the arms and legs
combined should be considered no sooner than a 12 to 16-week window after the previous
treatment session.

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.
