1. What Dysport is and what it is used for

Dysport is presented as a powder for solution for injection. Each vial contains 500 units of botulinum toxin type A.

Dysport belongs to a group of medicines called other peripheral muscle relaxants. It is a toxin produced by a bacterium, Clostridium botulinum, which acts by blocking nerve impulses to the muscles injected, causing the muscle to stop contracting.

Dysport will be administered by your doctor. In adults, it will be administered to control muscle spasms of the eyelids, face, neck, and shoulders, as well as the arm and leg in people who have suffered a stroke. In children aged 2 years or older with cerebral palsy, it will be administered to control spasticity in the leg muscles associated with deformity and to control spasticity in the arm muscles.

Dysport is also used in adults for the treatment of urinary incontinence (loss of bladder control) due to bladder problems associated with spinal cord injury or multiple sclerosis in patients who regularly perform clean intermittent catheterization.

2. What you need to know before using Dysport

Do not use Dysport:

• If you are allergic (hypersensitive) to botulinum toxin or any of the other ingredients of Dysport (listed in section 6).
• If you have a urinary tract infection at the time of receiving treatment for urinary incontinence.

Warnings and precautions:

Talk to your doctor, pharmacist, or nurse before using Dysport, especially in the following situations:

• If you notice problems swallowing, speaking, or breathing, contact your doctor immediately or go to the emergency room. In a small number of cases, these side effects could be serious or even fatal.

• If you have had an adverse reaction to a medicine that contained botulinum toxin.

• If you have a neuromuscular transmission disorder (e.g., myasthenia gravis); this may make you more sensitive to the effect of Dysport, which may result in excessive muscle weakness.

• If you have weakness or atrophy of the muscles into which your doctor intends to inject the product.

• If you have bleeding problems or have an infection or inflammation in the muscles into which your doctor needs to inject Dysport.

• Be careful if you receive treatment for muscle spasms of the leg due to a higher risk of falls in adults, especially in older people.

• If the muscles at the proposed injection sites show signs of wear.

When Dysport is used in the muscles surrounding the eye, your eyes may become dry (see section 4), which could damage the surface of your eyes. To avoid this, you may need treatment with protective drops, ointments, or a protective cover that closes the eye. Your doctor will indicate its use if necessary.

At the time of injection into the bladder to treat urinary incontinence, due to the procedure by which the injection is administered, you may experience an uncontrolled reflex reaction of your body (autonomic dysreflexia, e.g., profuse sweating, sharp headache, increased blood pressure or pulse).

Children and adolescents

Dysport will only be used in children aged 2 years or older for the treatment of spasticity of the legs in children. The safety and efficacy of the specialty for treatment in children for other indications have not been demonstrated.

Use of other medicines:

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

You should be careful when taking antibiotics to treat an infection or muscle relaxants. Some of these medicines may increase the effect of Dysport.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

You should not use Dysport during pregnancy unless it is clearly necessary and the benefits outweigh any possible risks to the fetus.

Treatment with Dysport is not recommended if you are breastfeeding, as it is not known whether Dysport passes into breast milk.

Driving and using machines

You may experience blurred vision or temporary muscle weakness after treatment with Dysport. If this happens, do not drive or use machines.

Important information about some of the ingredients of Dysport:

This medicine contains human albumin in very small amounts. It meets all current requirements for quality and safety, but it cannot be completely ruled out that there is a risk of transmitting viral infections.

3. How to use Dysport

The Dysport vial will only be used for you and only for one treatment session.

This medicine will always be administered by your doctor; therefore, you will never self-administer it. Your doctor will determine the dose you need, the muscles to be injected, and the number and frequency of injections.

For the treatment of neck and shoulder muscle spasms

The recommended dose will be a total of 500 units, which the doctor will divide between the most affected muscles to be injected. Injections will be given approximately every 12 weeks, depending on the relaxation achieved with previous administrations. The maximum dose should not exceed 1000 units.

For the treatment of eyelid and facial muscle spasms

For eyelid spasms, if both eyelids are affected, approximately 40 units will be injected per eye. Injections will be given approximately every 12 weeks, when the relaxing effect starts to disappear. In subsequent visits, the dose may be increased up to a maximum of 120 units per eye. The medicine will be injected under the skin at different points around the eye.

If you have a facial spasm, it will be treated as if you had a spasm of a single eyelid.

For the treatment of arm muscle spasms after a stroke

The recommended dose, which should not be exceeded, will be 1000 units, but when the shoulder muscles are also injected, the dose may be increased up to 1500 units. Your doctor may divide the total dose between the affected arm and shoulder muscles. Improvement in muscle spasms will usually be observed within 1 week after administration. Injections may be repeated with a frequency of 12 to 16 weeks.

For the treatment of leg muscle spasms after a stroke

The recommended dose, which should not be exceeded, will be 1500 units. The doctor may divide the dose between the affected leg muscles. Injections may be repeated with a frequency of 12 to 16 weeks.

For the treatment of arm and leg muscle spasms

If you need to receive injections in the arm and leg during the same treatment session, your doctor may divide the dose between your arm and leg, but the total dose should not exceed 1500 units.

For the treatment of muscle spasms in the legs in children with cerebral palsy

For children aged 2 years or older: the doctor will decide the dose. Dysport will be injected into the affected leg muscles. The dose should not be greater than 1000 units or 30 units/kg per treatment session, repeated every 16-22 weeks, or as needed, but never less than 12 weeks.

For the treatment of muscle spasms in the arms in children with cerebral palsy

For children aged 2 years or older: the doctor will decide the dose. Dysport will be injected into the affected arm muscles. If the treatment is injected into one arm, the dose should not be greater than 640 units or 16 units/kg per treatment session, whichever is lower. If the treatment is injected into both arms, the dose should not be greater than 840 units or 21 units/kg per treatment session, whichever is lower. Muscle spasms should improve in the weeks following treatment, and this improvement may last up to 34 weeks. Your doctor will repeat the treatment approximately every 16-28 weeks, or as needed, but never less than 16 weeks.

For the treatment of muscle spasms in the arms and legs in children with cerebral palsy

If you need to receive injections in the arms and legs during the same treatment session, the dose of Dysport to be injected into each limb will be decided by the doctor, but the total dose should not exceed 1000 units per session or 30 units/kg, whichever is lower. The treatment may be repeated no sooner than 12-16 weeks after the previous treatment session.

For the treatment of urinary incontinence

The first dose administered into the bladder muscle will be 600 units, but your doctor may decide to increase the dose to 800 units in subsequent injections.

Dysport will be administered through a procedure called cystoscopy. An instrument with a light source at the end will be inserted into the bladder through the opening through which urine is expelled (called the urethra). This allows the doctor to see the inside of the bladder and administer the Dysport injections into the bladder wall. You will only be given Dysport if you are already performing clean intermittent catheterization (CIC). CIC is a procedure during which a catheter (a soft, hollow tube that is inserted into the urethra to help empty the urine from the bladder) is temporarily inserted into the bladder and removed once the bladder is empty. Ask your doctor to explain more details about the procedure.

You will need to take antibiotics to prevent a urinary tract infection. If you are taking anticoagulant medicines, your doctor will adjust your treatment before and after the Dysport injections. You may be given a local or general anesthetic or a sedative before the injections. You will be observed for at least 30 minutes after the injections. Symptoms usually improve within two weeks, and the improvement may last up to 48 weeks. Your doctor will repeat the treatment as needed, but no more frequently than every 12 weeks.

If you use more Dysport than you should:

If you receive more Dysport than you should, other muscles different from those injected may start to weaken. This may not happen immediately. If it happens, tell your doctor as soon as possible. If you have difficulty swallowing, breathing, or speaking, go to the emergency room urgently.

In case of overdose or accidental ingestion, consult the Toxicology Information Service, telephone 91.562.04.20.

If you miss a dose of Dysport:

If you forget to go to the hospital for the next Dysport injection, nothing will happen to you, except that you may notice that muscle stiffness or spasms return to what they were before treatment with Dysport. Consult your doctor, and they will decide when you need the next injection.

If you stop treatment with Dysport:

The relaxing effect may eventually disappear, and muscle contractions will return to what they were before treatment.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

Treatment of Arms and Legs in Children with Cerebral Palsy

There are no specific findings for the administration of Dysport in the same treatment session in the arm and leg compared to those expected when treating the arm or leg separately.

Excessive weakening of the affected muscle and/or localized diffusion of Dysport to other muscles may result in accidental injuries from falls and abnormal gait.

All these effects, if they occur, would be noticeable a few days after injection and normally disappear within 2 to 4 weeks. If any of these adverse effects become bothersome or concern you, tell your doctor.

Treatment of Urinary Incontinence due to Uncontrolled Contractions of the Bladder Muscle

Frequent:

• Blood in the urine *
• Constipation
• Bacteria in the urine*.
• Erectile dysfunction, sometimes known as impotence
• Urinary tract infection*
• Headache
• Fever

Infrequent:

• Numbness
• Muscle weakness

• Bleeding from the bladder or the urethra (the tube that carries urine from the bladder to the outside of the body)

*This adverse effect may be related to the procedure

Post-Marketing Experience

The profile of adverse reactions reported to the Company during the use of the medication after its market release corresponds to that observed during clinical trials. Sporadically, cases of hypersensitivity (allergy) have been reported.

Very rarely, adverse reactions resulting from the onset of toxin effects at remote sites from the injection site (excessive muscle weakness, difficulty swallowing, aspiration pneumonia that can be fatal) have been reported.
