Further information

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.
In adults less than 65 years of age, BOTOX is used for the
temporary improvement of vertical lines between the eyebrows
seen at frown, when the severity of these lines has an important
psychological impact for the patient.
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.

2. BEFORE YOU USE BOTOX
Do NOT use BOTOX




1. WHAT BOTOX IS AND WHAT IT IS USED FOR
What BOTOX is

BOTOX is a muscle relaxant that is injected into the muscles 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.

What BOTOX is used for

In adults, BOTOX is used to control:
• persistent muscle spasms in the eyelid and face;
• persistent muscle spasms in the neck and shoulders;
• persistent muscle spasms in the wrist and hand of patients
who have suffered a stroke;
• excessive sweating of the armpits that affects the activities
of daily living, when other local treatments do not help;
• 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.
In adults, BOTOX is used to prevent:
• headaches in patients with chronic migraine



if you are allergic (hypersensitive) to botulinum toxin type
A or any of the other ingredients of BOTOX;
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.

Take special care with BOTOX
Before using BOTOX

Tell your doctor if you:
• have had any problems with injections (such as fainting) in
the past;
• have had problems in the past with previous botulinum toxin
injections;
• have inflammation in the muscles or skin area where your
doctor plans to inject;
• have significant weakness or wasting of the muscles which
your doctor plans to inject;
• 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;
• 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);
• 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;
• have had any surgery that may have in some way changed
the muscle to be injected;
• will have an operation soon;
• are taking any blood thinning medicine.

After you have been given BOTOX

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 lines, please inform your
doctor if you see no significant improvement of your lines
one month after your first course of treatment.

Perforation

General precautions

If you are given BOTOX too often or the dose is too high, 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.
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 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.

The dosage of BOTOX and the duration of its effect will vary
depending on the condition for which you are treated. Below are
details corresponding to each condition.


The safety and effectiveness of BOTOX in the treatment
of persistent muscles spasms of the eyelid, face, neck
and shoulder in children (under 12 years) have not been
demonstrated;



The safety and effectiveness of BOTOX in the treatment
of chronic migraine have not been studied in children
(under 18 years);



The safety and effectiveness of BOTOX in the treatment
of vertical lines between the eyebrows in individuals under
18 years of age have not been demonstrated and such use is
not recommended;



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

Taking other medicines

Tell your doctor or pharmacist if:
• you are using any antibiotics (used to treat infections),
anticholinesterase medicines, medicines to control your heart
rhythm, or muscle relaxants. Some of these medicines may
increase the effect of BOTOX.
• you have recently been injected with a medicine
containing 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).
Please tell your doctor or pharmacist if you are taking or have
recently taken any other medicines, including medicines obtained
without a prescription.

Pregnancy and breast-feeding

The use of BOTOX is not recommended during pregnancy and in
women of childbearing potential not using contraception unless
clearly necessary. Contact your doctor if you are pregnant, plan
pregnancy or become pregnant whilst being treated. Your doctor
will discuss with you whether you should continue with your
treatment.
BOTOX is not recommended in breast-feeding women.
Ask your doctor or pharmacist for advice before taking any
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 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 the elderly are the same as for other adults.

The safety and effectiveness of BOTOX in the treatment
of excessive sweating of the armpits have not been
investigated in children under 12 years. There is limited
experience with BOTOX in the treatment of excessive
sweating of the armpits in adolescents between age of
12 and 17 using BOTOX. The effectiveness of BOTOX in this
population has not been confirmed. Speak to your doctor for
further information;



The safety and effectiveness of BOTOX in the treatment of
upper limb spasticity associated with stroke have not been
established in children and adolescents under 18 years of age;



The safety and effectiveness of BOTOX in the treatment of
leakage of urine have not been established in children under
18 years;



There is limited clinical data with BOTOX in the treatment of
vertical lines between the eyebrows in patients older than
65 years and until more studies have been performed, BOTOX
is not recommended in this age group.

For persistent muscle spasms of the eyelid and face

Dosage
In the first treatment session, your doctor may give multiple
injections in the affected muscles with 1.25 to 2.5 Units of BOTOX
into each injection site.
The maximum dose for the first treatment session is 25 Units per
affected area (for example per eye). For the following treatment
sessions, the total maximum dose can be increased up to
100 Units, if needed.
Duration of treatment effect
You will usually see an improvement within 3 days after the
injection.
The maximum effect is usually seen 1 to 2 weeks after treatment.
When the effect starts to wear off, you can have the treatment
again if needed, but not more often than every 3 months.

For persistent muscle spasms of the neck and
shoulders

Dosage
Your doctor may give multiple injections in the affected muscles
with up to 50 Units of BOTOX into each injection site.
The maximum dose for the first treatment session is 200 Units.
Duration of treatment effect
When the effect starts to wear off, you can have the treatment
again if needed, but not more often than every 12 weeks.

For persistent muscle spasms in the wrist and hand
of patients who have had a stroke
Dosage
Your doctor may give multiple injections in the affected muscles.
The dose and number of injections will vary depending on
a number of factors, including your needs, the muscles to be
injected, the size of the muscles, severity of spasms, etc.

Duration of treatment effect
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.
When the effect starts to wear off, you can have the treatment
again if needed, but not more often than every 12 weeks.

For excessive sweating of the armpits

Dosage
Your doctor will give multiple injections with a total of 50 Units of
BOTOX in each armpit.
Duration of treatment effect
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.
When the effect starts to wear off, you can have the treatment
again if needed.

For persistent muscle spasms in the legs of children
who have cerebral palsy
Dosage
The doctor may give multiple injections in the affected muscles.
The dose will depend on the weight of your child.

Duration of treatment effect
The improvement usually appears within the first 2 weeks after the
injection.
When the effect starts to wear off, further treatment is possible,
but not more often than every 2 months.

For the prevention of headache in adults who have
chronic migraine

Dosage
Your doctor may give you multiple injections (between 31 and
39) in 7 muscular groups of the face, head, neck and shoulders,
with up to 5 Units of BOTOX into each injection site. Injections are
divided across muscles in your forehead, your temples on the side
of your head, the back of your head, your upper neck area, and
your shoulders. The injections are given to both the left, and right
side of these head and neck muscles, except for one injection
given to the muscle that is between your eyebrows
The total dose range is between 155 Units and 195 Units per
treatment session.
Duration of treatment effect
When the effect starts to wear off, further treatment is possible,
but not more often than every 12 weeks.

For overactive bladder with leakage of urine

Dosage
Your doctor will give multiple injections into the bladder wall. The
total dose is 100 Units of BOTOX.
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.
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.
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.
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.
Duration of treatment effect
You will usually see an improvement within 2 weeks after the
injection.
Typically the effect lasts approximately 6 months after the injection.
When the effects start to wear off, you can have the treatment
again if needed, but not more often than every 3 months.

For leakage of urine due to neurogenic bladder

Dosage
Your doctor will give multiple injections into the bladder wall.
The total dose is 200 Units of BOTOX.
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. 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).
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.
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.
Duration of treatment effect
You will usually see an improvement within 2 weeks after the
injection.
Typically the effect lasts approximately 10 months after the
injection.
When the effects start to wear off, you can have the treatment
again if needed, but not more often than every 3 months.

For vertical lines between your eyebrows

The usual dose is 20 Units. You will be injected with the
recommended volume of 0.1 millilitre (ml) (4 Units) of BOTOX into
each of 5 injection sites.
Improvement of severity of the lines located between the eyebrows
generally occurs within one 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.
The interval between two treatments must not be less than
three months.

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:
• 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.

The following information is intended for
medical or healthcare professionals only:
Please refer to the Summary of Product
Characteristics for complete prescribing
information for BOTOX.
For all indications:
Side effects related to spread of toxin distant from the site of administration
have been reported, sometimes resulting in death, which in some cases
was associated with dysphagia, pneumonia and/or significant debility.
The symptoms are consistent with the mechanism of action of botulinum
toxin and have been reported hours to weeks after injection. The risk of
symptoms is probably greatest in patients who have underlying conditions
and comorbidities that would predispose them to these symptoms,
including children and adults treated for spasticity, and are treated with
high doses.
Patients treated with therapeutic doses may also experience exaggerated
muscle weakness.
Pneumothorax associated with injection procedure has been reported
following administration of BOTOX near the thorax. Caution is warranted
when injecting in proximity to the lung, particularly the apices.
Serious adverse events including fatal outcomes have been reported
in patients who had received off-label injections of BOTOX directly into
salivary glands, the oro-lingual-pharyngeal region, oesophagus and
stomach. Some patients had pre-existing dysphagia or significant debility.
Reconstitution of the medicinal product:
It is good practice to perform vial reconstitution and syringe preparation
over plastic-lined paper towels to catch any spillage.
Reconstitute BOTOX only with sterile unpreserved normal saline
(0.9% sodium chloride for injection). Draw up an appropriate amount of
diluent (see dilution table or instructions below) into a syringe.

Since BOTOX is denatured by bubbling or similar vigorous agitation, inject
the diluent gently into the vial. Discard the vial if a vacuum does not pull the
diluent into the vial. Reconstituted BOTOX is a clear colourless to slightly
yellow solution free of particulate matter. The reconstituted solution should
be visually inspected for clarity and absence of particles prior to use. When
reconstituted in the vial, BOTOX may be stored in a refrigerator (2°C - 8°C)
for up to 24 hours prior to use.
From a microbiological point of view, the product should be used
immediately. If not used immediately, in-use storage times and conditions
prior to use are the responsibility of the user and would normally not be
longer than 24 hours at 2°C - 8°C.
Dilution instructions for treatment of urinary incontinence due to
overactive bladder:
It is recommended that a 100 Unit or two 50 Unit vials are used for
convenience of reconstitution.
Should you need to use a 200 Unit vial, reconstitute a 200 Unit vial of
BOTOX with 8 ml of 0.9% non-preserved saline solution and mix gently.
Draw 4 ml from the vial into a 10 ml syringe. Complete the reconstitution by
adding 6 ml of 0.9% non-preserved saline solution into the 10 ml syringe
and mix gently. This will result in a 10 ml syringe containing a total of
100 Units of reconstituted BOTOX. Use immediately after reconstitution
in the syringe. This product is for single use only and any unused
reconstituted product should be disposed of. Dispose of any unused
saline.

4. POSSIBLE SIDE EFFECTS

Or, reconstitute a 100 Unit vial of BOTOX with 10 ml of 0.9% nonpreserved saline solution and mix gently. Draw the 10 ml from the vial
into a 10 ml syringe. This will result in a 10 ml syringe containing a total of
100 Units of reconstituted BOTOX. Use immediately after reconstitution in
the syringe. Dispose of any unused saline.

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

Or reconstitute two 50 Unit vials of BOTOX, each with 5 ml of 0.9%
non-preserved saline solution and mix each vial gently. Draw the 5 ml
from each vial into a single 10 ml syringe. This will result in a single 10 ml

syringe containing a total of 100 Units of reconstituted BOTOX. Use
immediately after reconstitution in the syringe. Dispose of any unused
saline.
Dilution instructions for treatment of Urinary incontinence due to
neurogenic detrusor overactivity:
It is recommended that a 200 Unit or two 100 Unit vials are used for
convenience of reconstitution
Reconstitute a 200 Unit vial of BOTOX with 6 ml of 9 mg/ml (0.9%)
preservative-free sodium chloride solution for injection and mix gently.
Draw 2 ml from the vial into each of three 10 ml syringes. Complete the
reconstitution by adding 8 ml of 9 mg/ml (0.9%) preservative-free sodium
chloride solution for injection into each of the 10 ml syringes, and mix
gently. This will result in three 10 ml syringes containing a total of 200 Units
of reconstituted BOTOX. Use immediately after reconstitution in the
syringe. Dispose of any unused saline.
Or, reconstitute two 100 Unit vials of BOTOX, each with 6 ml of 9 mg/ml
(0.9%) preservative-free sodium chloride solution for injection and mix the
vials gently. Draw 4 ml from each vial into each of two 10 ml syringes. Draw
the remaining 2 ml from each vial into a third 10 ml syringe. Complete the
reconstitution by adding 6 ml of 9 mg/ml (0.9%) preservative-free sodium
chloride solution for injection into each of the 10 ml syringes, and mix
gently. This will result in three 10 ml syringes containing a total of 200 Units
of reconstituted BOTOX. Use immediately after reconstitution in the
syringe. Dispose of any unused saline.
Should you need to use 50 Unit vials, reconstitute four 50 Unit vials
of BOTOX, each with 3 ml of 9 mg/ml (0.9%) preservative-free sodium
chloride solution for injection and mix the vials gently. Draw 3 ml from the
first vial and 1 ml from the second vial into one 10 ml syringe. Draw 3 ml
from the third vial and 1 ml from the fourth vial into a second 10 ml syringe.
Draw the remaining 2 ml from the second and fourth vials into a third 10 ml
syringe. Complete the reconstitution by adding 6 ml of 9 mg/ml (0.9%)
preservative-free sodium chloride solution for injection into each of the
three 10 ml syringes, and mix gently. This will result in three 10 ml syringes
containing a total of 200 Units of reconstituted BOTOX. Use immediately
after reconstitution in the syringe. Dispose of any unused saline.
This product is for single use only and any unused solution should be
discarded.
Procedure to follow for safe disposal of vials, syringes and
materials used
For safe disposal, unused vials should be reconstituted with a small
amount of water and then autoclaved. Any used vials, syringes, and
spillages etc. should be autoclaved, or the residual BOTOX inactivated
using dilute hypochlorite solution (0.5%) for 5 minutes.
Identification of the product
In order to verify receipt of actual BOTOX product from Allergan, look for
a holographic film on the vial label. In order to see this film, examine the
vial under a desk lamp or fluorescent light source. Rotating the vial back
and forth between your fingers, look for horizontal lines of rainbow colour
on the label and confirm that the name “Allergan” appears within the
rainbow lines. (Note that the film on the label is absent in the Expiry/Lot
Number area.) If you do not see the rainbow lines or the name ”Allergan”
does not appear, do not use the product and contact your local Allergan
office for additional information.

If you experience hives, swelling including swelling of the
face or throat, wheezing, feeling faint and shortness of
breath, contact your doctor immediately.





Like all medicines, BOTOX can cause side effects, although not
everybody gets them. In general, side effects occur within the first
few days following injection.
They usually last only for a short time, but they may last for several
months and in rare cases, longer.



As expected for any injection procedure, pain/burning/stinging,
swelling and/or bruising may be associated with the injection.
The side effects are classified into the following categories,
depending on how often they occur:
Very common
Common
Uncommon
Rare
Very rare

occur in more than 1 out of 10 people who use
the medicine

occur in less than 1 out of 10 people but more
than 1 out of 100 people who use the medicine
occur in less than 1 out of 100 people but
more than 1 out of 1,000 people who use the
medicine
