WHAT TEMOZOLOMIDE IS AND WHAT IT IS USED FOR
This medicine is an antitumour agent.
Temozolomide is used for the treatment of specific forms of brain tumours:
In adults with newly-diagnosed glioblastoma multiforme. Temozolomide is first used together with
radiotherapy (concomitant phase of treatment) and after that alone (monotherapy phase of treatment).
in children 3 years and older and adult patients with malignant glioma, such as glioblastoma
multiforme or anaplastic astrocytoma. Temozolomide is used in these tumours if they return or get
worse after standard treatment.
WHAT YOU NEED TO KNOW BEFORE YOU TAKE TEMOZOLOMIDE
Do not take Temozolomide
if you are allergic to temozolomide or any of the other ingredients of this medicine (listed in section
6).if you have had an allergic reaction to dacarbazine (an anticancer medicine sometimes called
DTIC). Signs of allergic reaction include feeling itchy, breathlessness or wheezing, swelling of the
face, lips, tongue or throat.
if certain kinds of blood cells are severely reduced (myelosuppression), such as your white blood cell
count and platelet count. These blood cells are important for fighting infection and for proper blood
clotting. Your doctor will check your blood to make sure you have enough of these cells before you
Warnings and precautions
Talk to your doctor, pharmacist or nurse before taking Temozolomide
as you should be observed closely for the development of a serious form of chest infection called
Pneumocystis jirovecii pneumonia (PCP). If you are a newly-diagnosed patient (glioblastoma
multiforme) you may be receiving Temozolomide for 42 days in combination with radiotherapy. In
this case, your doctor will also prescribe medicine to help you prevent this type of pneumonia (PCP).

if you have ever had or might now have a hepatitis B infection. This is because temozolomide could
cause hepatitis B to become active again, which can be fatal in some cases. Patients will be carefully
checked by their doctor for signs of this infection before treatment is started.
if you have low counts of red blood cells (anaemia), white blood cells and platelets, or blood clotting
problems before starting the treatment, or if you develop them during treatment. Your doctor may
decide to reduce the dose, interrupt, stop or change your treatment. You may also need other
treatments. In some cases, it may be necessary to stop treatment with Temozolomide. Your blood will
be tested frequently during treatment to monitor the side effects of Temozolomide on your blood cells.
as you may have a small risk of other changes in blood cells, including leukaemia.
if you have nausea (feeling sick in your stomach) and/or vomiting which are very common side effects
of Temozolomide (see section 4), your doctor may prescribe you a medicine (an anti-emetic) to help
If you vomit frequently before or during treatment, ask your doctor about the best time to take
Temozolomide until the vomiting is under control. If you vomit after taking your dose, do not take a
second dose on the same day.
if you develop fever or symptoms of an infection contact your doctor immediately.
if you are older than 70 years of age, you might be more prone to infection, bruising or bleeding.

Dosage and duration of treatment
Your doctor will work out your dose of Temozolomide. This is based on your size (height and weight) and if
you have a recurrent tumour and have had chemotherapy treatment in the past.
You may be given other medicines (anti-emetics) to take before and/or after taking Temozolomide to prevent
or control nausea and vomiting.
Patients with newly-diagnosed glioblastoma multiforme
If you are a newly-diagnosed patient, treatment will occur in two phases:
treatment together with radiotherapy (concomitant phase) first
followed by treatment with only Temozolomide (monotherapy phase).
During the concomitant phase, your doctor will start Temozolomide at a dose of 75 mg/m² (usual dose). You
will take this dose every day for 42 days (up to 49 days) in combination with radiotherapy. The
Temozolomide dose may be delayed or stopped, depending on you blood counts and how you tolerate your
medicine during the concomitant phase.
Once the radiotherapy is completed, you will interrupt treatment for 4 weeks. This will give your body a
chance to recover.
Then, you will start the monotherapy phase.
During the monotherapy phase, the dose and way you take Temozolomide will be different. Your doctor will
work out your exact dose. There may be up to 6 treatment periods (cycles). Each one lasts 28 days. You will
take your new dose of Temozolomide alone once daily for the first 5 days (“dosing days”) of each cycle. The
first dose will be 150 mg/m². Then you will have 23 days without Temozolomide. This adds up to a 28-day
After Day 28, the next cycle will begin. You will again take Temozolomide once daily for 5 days followed
by 23 days without Temozolomide. The Temozolomide dose may be adjusted, delayed or stopped depending
on your blood counts and how you tolerate your medicine during each treatment cycle.
Patients with tumours that have returned or worsened (malignant glioma, such as glioblastoma multiforme
or anaplastic astrocytoma) taking Temozolomide only
A treatment cycle with Temozolomide lasts 28 days.
You will take Temozolomide alone once daily for the first 5 days. This daily dose depends on whether or not
you have received chemotherapy before.
If you have not been previously treated with chemotherapy, your first dose of Temozolomide will be
200 mg/m² once daily for the first 5 days. If you have been previously treated with chemotherapy, your first
dose of Temozolomide will be 150 mg/m² once daily for the first 5 days.
Then, you will have 23 days without Temozolomide. This adds up to a 28-day treatment cycle.
After Day 28, the next cycle will begin. You will again receive Temozolomide once daily for 5 days,
followed by 23 days without Temozolomide.
Before each new treatment cycle, your blood will be tested to see if the Temozolomide dose needs to be
adjusted. Depending on your blood test results, your doctor may adjust your dose for the next cycle.
How to take Temozolomide
Take your prescribed dose of Temozolomide once a day, preferably at the same time each day.

POSSIBLE SIDE EFFECTS
Like all medicines, Temozolomide can cause side effects, although not everybody gets them.
Contact your doctor immediately if you have any of the following:
a severe allergic (hypersensitive) reaction (hives, wheezing or other breathing difficulty)
severe headache that does not go away
Temozolomide treatment can cause a reduction in certain kinds of blood cells. This may cause you to have
increased bruising or bleeding, anaemia (a shortage of red blood cells), fever, and reduced resistance to
infections. The reduction in blood cell counts is usually short-lived. In some cases, it may be prolonged and
Page 4 of 7
may lead to a very severe form of anaemia (aplastic anaemia). Your doctor will monitor your blood regularly
for any changes, and will decide if any specific treatment is needed. In some cases, your Temozolomide dose
will be reduced or treatment stopped.
