1. What BOTOX is and what it is used for

BOTOX is a muscle relaxant used to treat a number of conditions within the body. It contains the active substance Botulinum toxin type A and is injected into either the muscles, the bladder wall or deep into the skin. It works by partially blocking the nerve impulses to any muscles that have been injected and reduces excessive contractions of these muscles. In the case of chronic migraine, it is thought that BOTOX blocks pain signals, which indirectly block the development of a migraine.

When injected into the skin, BOTOX works on sweat glands to reduce the amount of sweat produced.

When injected into the bladder wall, BOTOX works on the bladder muscle to prevent leakage of urine (urinary incontinence) due to uncontrolled contractions of the bladder muscle.

1. BOTOX can be injected directly into the muscles, and can be used to control the following conditions:

  • In children aged two years or older with cerebral palsy, who can walk, BOTOX is used to control foot deformity caused by the persistent muscle spasms in the legs. BOTOX relieves the persistent muscle spasms in the leg.
  • In adults:
    • persistent muscle spasms in the wrist, hand or ankle of patients who have suffered a stroke;
    • persistent muscle spasms in the eyelid and face;
    • persistent muscle spasms in the neck and shoulders.

2. BOTOX is used to prevent headaches in adult patients with chronic migraine.

Chronic migraine is a disease affecting the nervous system. To be diagnosed with chronic migraine, you must have headaches 15 days or more a month. In addition, on 8 or more days a month, your headaches must have at least two of the following characteristics:

  • affect only one side of the head
  • cause a pulsating pain
  • cause moderate to severe pain
  • are aggravated by routine physical activity

and they must cause at least one of the following:

  • nausea, vomiting, or both
  • sensitivity to light and sound.

BOTOX has been shown to significantly reduce the frequency of days with headache and to improve the quality of life of patients suffering from chronic migraine. After two treatment sessions, approximately 47% of patients had a 50% or greater reduction from baseline in the number of days with headache they experienced.

3) When injected into the bladder wall, BOTOX works on the bladder muscle to reduce leakage of urine (urinary incontinence) and control the following conditions in adults:

  • overactive bladder with leakage of urine, the sudden urge to empty your bladder and needing to go to the toilet more than usual;
  • leakage of urine due to bladder problems associated with spinal cord injury or multiple sclerosis.

In patients who have not managed to control overactive bladder with leakage of urine with medicines called anticholinergics, BOTOX has been shown to reduce leakage of urine from an average of about 5 episodes per day down to 2 after 12 weeks. 27% of patients had no leakage of urine at all.

In patients with bladder problems associated with spinal cord injury or multiple sclerosis who have not managed to control leakage of urine with medicines called anticholinergics, BOTOX has been shown to reduce leakage of urine, from an average of about 30 episodes per week down to 10 after 6 weeks. 37% of patients had no leakage of urine at all.

4) In adults, BOTOX can be injected deep into the skin and can work on sweat glands to reduce excessive sweating of the armpits, which affects the activities of daily living when other local treatments do not help.

5) When the severity of the following facial lines has an important psychological impact in adult patients, BOTOX is used for the temporary improvement in the appearance of:

  • Vertical lines between the eyebrows seen at maximum frown.
  • Fan-shaped lines from the corner of the eyes seen at maximum smile.
  • Fan-shaped lines from the corner of the eyes seen at maximum smile when treated at the same time as vertical lines between the eyebrows seen at maximum frown.

2. What you need to know before you use BOTOX

Do not use BOTOX

  • if you are allergic (hypersensitive) to botulinum toxin type A or any of the other ingredients of this medicine (listed in section 6);
  • if you have an infection at the proposed site of injection;
  • when you are being treated for leakage of urine and have either a urinary tract infection or a sudden inability to empty your bladder (and are not regularly using a catheter), or if you have bladder stones;
  • if you are being treated for leakage of urine and are not willing to begin using a catheter if required.

Warnings and precautions

Talk to your doctor or pharmacist before using BOTOX:

  • if you have ever had problems with swallowing or food or liquid accidentally going into your lungs, especially if you will be treated for persistent muscle spasms in the neck and shoulders;
  • if you are over 65 years of age and have other serious illnesses;
  • if you suffer from any other muscle problems or chronic diseases affecting your muscles (such as myasthenia gravis or Eaton Lambert Syndrome);
  • suffer from certain diseases affecting your nervous system (such as amyotrophic lateral sclerosis or motor neuropathy);
  • if you have significant weakness or wasting of the muscles which your doctor plans to inject;
  • if you have had any surgery that may have in some way changed the muscle to be injected;
  • if you have had any problems with injections (such as fainting) in the past;
  • if you have inflammation in the muscles or skin area where your doctor plans to inject;
  • if you have had problems in the past with previous botulinum toxin injections;
  • if you suffer from cardiovascular disease (disease of the heart or blood vessels);
  • if you suffer of have suffered from seizures;
  • if you have an eye disease called closed-angle glaucoma (high pressure in the eye) or were told you are at risk for developing this type of glaucoma;
  • if you will have an operation soon;
  • if you are taking any blood thinning medicine.

After you have been given BOTOX

You or your caregiver should contact your doctor and seek medical attention immediately if you experience any of the following:

  • difficulty in breathing, swallowing, or speaking;
  • hives, swelling including swelling of the face or throat, wheezing, feeling faint and shortness of breath (possible symptoms of severe allergic reaction).

If you have been treated for vertical and/or fan-shaped lines, please inform your doctor if you see no significant improvement of your lines one month after your first course of treatment.

General precautions

As with any injection, it is possible for the procedure to result in infection, pain, swelling, burning and stinging, increased sensitivity, tenderness, redness, and/or bleeding/bruising at the site of injection.

Side effects possibly related to the spread of toxin distant from the site of administration have been reported with botulinum toxin (e.g. muscle weakness, difficulty swallowing or unwanted food or liquid in the airways). This is a particular risk for patients with an underlying illness that makes them susceptible to these symptoms.

If you are given BOTOX too often or the dose is too high, you may experience muscle weakness and side effects related to the spread of toxin, or your body may start producing some antibodies, which can reduce the effect of BOTOX. To limit this risk, the interval between two treatments must not be less than two or three months depending on the indication.

When BOTOX is used in the treatment of a condition that it is not listed in this leaflet, it could result in serious reactions, particularly in patients who already experience difficulty in swallowing or have significant debility.

If you have not done much exercise for a long time before receiving BOTOX treatment, then after your injections you should start any activity gradually.

It is unlikely that this medicine will improve the range of motion of joints where the surrounding muscle has lost its ability to stretch.

When treating adults with post-stroke ankle muscle spasms, BOTOX should only be used if it is expected to result in improvement in function (e.g. walking) or symptoms (e.g. spasms or pain) or to help with patient care. Furthermore, for patients who may be more likely to fall, your doctor will judge if this treatment is suitable.

When BOTOX is used in the treatment of persistent muscle spasms in the eyelid, it could make your eyes blink less often, which may harm the surface of your eyes. In order to prevent this, you may need treatment with eye drops, ointments, soft contact lenses or even protective covering which closes the eye. Your doctor will tell you if this is required.

BOTOX does not prevent headaches in patients with episodic migraine, which occur less than 15 days a month.

When BOTOX is used in the treatment of vertical lines and fan-shaped lines drooping of eyelid may occur after treatment.

Other medicines with BOTOX

Tell your doctor or pharmacist if:

  • you are using any antibiotics (used to treat infections), or any medicines that affect the nerves that control muscles (for example anticholinesterase medicines or muscle relaxants). Some of these medicines may increase the effect of BOTOX.
  • you have recently been injected with a medicine containing a botulinum toxin (the active substance of BOTOX), as this may increase the effect of BOTOX too much.
  • you are using any anti-platelet (aspirin-like) products and/or anticoagulants (blood thinners).

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

Pregnancy and breast-feeding

The use of BOTOX is not recommended during pregnancy and in women of childbearing potential not using contraception. BOTOX is not recommended in breast-feeding women.

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

Driving and using machines

BOTOX may cause dizziness, sleepiness, tiredness or problems with your vision. If you experience any of these effects, do not drive or use any machines. If you are not sure, ask your doctor for advice.

3. How to use BOTOX

BOTOX must only be injected by doctors with specific skills and experience on how to use the medicine.

Method and route of administration

BOTOX is injected into your muscles (intramuscularly), into the bladder wall via a specific instrument (cystoscope) to inject into the bladder or into the skin (intradermally). It is injected directly into the affected area of your body; your doctor will usually inject BOTOX into several sites within each affected area.

General information about dosage

  • The number of injections per muscle and the dose vary depending on the indications. Therefore, your doctor will decide how much, how often, and in which muscle(s) BOTOX will be given to you. It is recommended that your doctor uses the lowest effective dose;
  • Dosages for older people are the same as for other adults.

Information for patients treated for leakage of urine

Your doctor will give you antibiotics around the time of the injection to help prevent urinary tract infection. The injection will be administered by a procedure called cystoscopy. An instrument with a light source at the end will be introduced into your bladder through the opening by which you let out the urine (called urethra). This enables the doctor to see the inside of the bladder and place the injections into the bladder wall. Please ask your doctor to explain further details of the procedure to you.

If you were not using a catheter (a soft, hollow tube that is inserted into your urethra to help empty urine from the bladder) before treatment with BOTOX, you should be seen by your doctor approximately 2 weeks after the injection. You will be asked to pass urine and will then have the volume of urine left in your bladder measured. If your doctor assesses you have too much urine left in your bladder you will be instructed to use a catheter to empty your bladder. Your doctor will decide if and when you need to return for the same test.

For overactive bladder with leakage of urine

You may be given a local anaesthetic before the injections (your bladder would be filled with anaesthetic solution for a while and then drained). You may also be given a sedative.

You will be observed for at least 30 minutes after the injection before you can leave to see if you can pass urine spontaneously.

You must contact your doctor if at any time you are unable to pass urine because it is possible that you may need to start using a catheter. In clinical trials, approximately 6 out of 100 patients not using a catheter before treatment may need to use a catheter after treatment.

For leakage of urine due to bladder problems associated with spinal cord injury or multiple sclerosis

You may be given a local or general anaesthetic before the procedure.

You will be observed for at least 30 minutes after the injection before you can leave. At the time of the injection, due to the procedure by which the injection is delivered into your bladder, you may experience possible uncontrolled reflex reaction of your body (e.g. profuse sweating, throbbing headache or increase in pulse rate).

You must contact your doctor if at any time you are unable to pass urine because it is possible that you may need to start using a catheter. In clinical trials, approximately one fifth of patients reported an inability to completely empty their bladder after BOTOX treatment. At least one third of patients not using a catheter before treatment may need to use a catheter after treatment.

Time to Improvement and Duration of Effect

For persistent muscle spasms in the legs of children who have cerebral palsy, the improvement usually appears within the first 2 weeks after the injection.

For persistent muscle spasms in the wrist and hand of patients who have had a stroke, you will usually see an improvement within the first 2 weeks after the injection. The maximum effect is usually seen about 4 to 6 weeks after treatment.

For persistent muscle spasms of the eyelid and face, you will usually see an improvement within 3 days after the injection and the maximum effect is usually seen after 1 to 2 weeks.

For persistent muscle spasms of the neck and shoulders, you will usually see an improvement within 2 weeks after the injection. The maximum effect is usually seen about 6 weeks after treatment.

For leakage of urine due to overactive bladder, you will usually see an improvement within 2 weeks after the injection. Typically patients find the effect lasts approximately 6-7 months after the injection.

For leakage of urine due to bladder problems associated with spinal cord injury or multiple sclerosis, you will usually see an improvement within 2 weeks after the injection. Typically patients find the effect lasts approximately 9-10 months after the injection.

For excessive sweating of the armpits, you will usually see an improvement within the first week after injection. On average the effect usually lasts 4-7 months after the first injection.

For vertical lines between the eyebrows seen at maximum frown, you will usually see an improvement within 1 week after treatment, the maximum effect being observed 5 to 6 weeks after injection. The treatment effect has been demonstrated for up to 4 months after injection.

For fan-shaped lines from the corner of the eyes seen at maximum smile you will usually see an improvement within 1 week after treatment. The treatment effect has been demonstrated for an average of 4 months after injection.

If you have received more BOTOX than you should

The signs of too much BOTOX may not appear for several days after the injection. Should you swallow BOTOX or have it accidentally injected, you should see your doctor who might keep you under observation for several weeks.

If you have received too much BOTOX, you may have any of the following symptoms and you must contact your doctor immediately. He/she will decide if you have to go to hospital:

  • muscle weakness which could be local or distant from the site of injection;
  • difficulty in breathing, swallowing or speaking due to muscle paralysis;
  • food or liquid accidentally going into your lungs which might cause pneumonia (infection of the lungs) due to muscle paralysis;
  • drooping of the eyelids, double vision;
  • generalised weakness.

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

4. Possible side effects

If you have any difficulty in breathing, swallowing or speaking after receiving BOTOX, contact your doctor immediately.
