Full Consumer Medicine Information (CMI)
This leaflet provides important information about using MAVENCLAD. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about using MAVENCLAD.
Where to find information in this leaflet:
1. Why am I using MAVENCLAD?
MAVENCLAD contains the active ingredient, cladribine. MAVENCLAD acts on cells in your immune system, known as lymphocytes, to reduce inflammation
in the nervous system caused by multiple sclerosis (MS).
MAVENCLAD is used to treat a type of MS known as relapsing remitting MS. In this type
of MS, MAVENCLAD has been shown to result in fewer relapses, less disease activity
in the brain and less progression of disability.
MAVENCLAD has been studied for safety and effectiveness when given as 2 treatment
courses over 2 years, each treatment course consists of 2 treatment weeks.
Following completion of the 2 treatment courses, no further cladribine treatment is
required in years 3 and 4.
Your doctor is the best person to discuss the long term effects of MAVENCLAD treatment
beyond above.
2. What should I know before I use MAVENCLAD?

the past. You may need vaccination prior to starting the treatment. After receiving
a treatment course you may be at risk of developing or experiencing infections, which
may be serious and severe. It is important you understand these risks and how to monitor
for them. Patients treated with MAVENCLAD may be at a higher risk for getting an infection.

your doctor will consider delaying the treatment until the infection is under control
or resolved.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins
or supplements you are taking and if these affect MAVENCLAD.
4. How do I use MAVENCLAD?
How much to take
MAVENCLAD is administered in two treatment courses over two years. Each treatment
course consists of two treatment weeks at the start of a 1 year period. For a treatment
week, you will be prescribed to take one or two tablets, once a day for 4-5 days.
Sometimes the number of tablets will vary from one week to the next.
The second treatment week will usually start 4 weeks after the start date of the first.
There is no MAVENCLAD treatment between the two courses.
Your doctor will decide the number of tablets per day (1 or 2) and number of treatment
days (4 or 5) depending on your body weight.
You may need to take the same number of tablets each day or some days you might take
2 tablets and then only 1 tablet on the following days.
Ask your doctor or pharmacist if you are unclear about how many tablets to take each
day.
If your doctor determines it to be appropriate, you will receive another course of
MAVENCLAD treatment (typically, 1 year after the first treatment course).
Follow the instructions provided when MAVENCLAD was prescribed.
When to take MAVENCLAD
Take MAVENCLAD at about the same time each day. You may take MAVENCLAD before or after
a meal.
How to take MAVENCLAD
Follow the instruction illustrated on the carton on how to open the child-resistant
pack. Your hands should be dry when handling the tablets.
Swallow the tablet(s) whole with water. Never cut or crush the tablets and do not
chew them or allow them to dissolve in your mouth.
Take the tablet(s) immediately after removal from the blister. Do not leave them exposed
on surfaces, e.g. on a table, or handle them longer than necessary.
If a tablet is left on a surface or if a broken or fragmented tablet is released from
the blister, wash the area thoroughly afterwards.
Wash your hands with soap and water after taking MAVENCLAD.
If you lose a tablet, contact your doctor or pharmacist for advice.
If you forget to use MAVENCLAD
MAVENCLAD should be used regularly at the same time each day. If you miss your dose
at the usual time and you remember on the same day you were supposed to take it, take
it on that day.
If you miss a dose and do not remember it until the following day, do not take the
missed dose along with the scheduled dose.
Do not take a double dose on the same day to make up for the dose you missed.
If you miss a dose, take the missed dose on the next day and extend the number of
days in that treatment course.
For example: If you forget to take the Day 3 dose and do not remember it until Day
4, take the Day 3 dose on Day 4, and take the Day 4 dose on Day 5. Extend the total
number of days in the treatment course by 1 day until the pack is empty.
If you miss 2 consecutive doses (e.g. both Day 3 and Day 4 doses), extend the treatment
course by 2 days. In this case, you will take your Day 3 dose on Day 5 and your Day
4 dose on Day 6.
If you use too much MAVENCLAD
If you think that you have used too much MAVENCLAD, you may need urgent medical attention.
You should immediately:
phone the Poisons Information Centre
(by calling
13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
If you take too much MAVENCLAD your white blood cells will be affected and you may
need additional blood tests. It may also be necessary to stop treatment with MAVENCLAD.
Your doctor will advise you.
5. What should I know while using MAVENCLAD?
Things you should do
Your doctor will check your blood before you start MAVENCLAD and at intervals during
and after treatment, to make sure that your treatment can be started or continued.
Make sure that you keep all appointments scheduled for these blood tests.
Keep all your doctor and blood test appointments so that your progress can be checked.
If you are about to be started on any new medicine or plan to have any vaccinations,
tell your doctor or pharmacist that you are taking or have taken MAVENCLAD. You should
not be vaccinated with 'live' or attenuated live vaccines during or after a MAVENCLAD
treatment, until your white blood cell counts return to normal.
If you are going to have a blood transfusion, tell the medical staff that you are
taking this medicine.
Also tell the medical staff if you are undergoing any procedures where a transfusion
may be required, e.g. surgery.
Special precautions may be required to prevent an unwanted reaction to the transfusion.
Stay out of the sun as much as possible. If you need to be in the sun, use a sunscreen
and wear a hat and shirt to protect your skin from the sun.
Although not known if related to MAVENCLAD, single events of cancer including melanomas,
have been seen in people after treatment. As a precautionary measure, you should follow
standard cancer screening recommendations, as advised by your doctor. Check your skin
regularly and have a doctor check your skin annually for new skin spots or changes
to existing spots, moles or freckles.
Call your doctor straight away if you:
If you think you have an infection. Symptoms of infections may include fever; aching,
painful muscles; headache; generally feeling unwell; loss of appetite. Your doctor
may delay treatment, or interrupt it, until the infection clears up.
If you get symptoms of shingles. Symptoms of shingles may include a 'band' of severe
pain and blistering rash, typically on one side of the upper body or the face; burning,
tingling, numbness or itchiness of the skin in the affected area; signs of infection
such as fever, headache or generally feeling unwell.
if you believe your MS is getting worse or if you notice any new symptoms (e.g. changes
in mood or behaviour, memory lapses, speech and communication difficulties). These
may be the symptoms of a rare brain disorder caused by infection and called progressive
multifocal leukoencephalopathy (PML). PML is a serious condition that may lead to
severe disability or death. PML has not yet been observed with MAVENCLAD.
If you or your partner becomes pregnant during or after your treatment with MAVENCLAD.
MAVENCLAD may affect the baby if either you or your partner is taking it. Both men
and women must use a proven method of birth control while taking and, for as long
as your doctor tells you to, after stopping MAVENCLAD. Both men and women should use
birth control for at least 6 months (6 menstrual cycles) after their last dose of
MAVENCLAD.
