If you are taking ASTROMIDE in combination treatment with radiation (newly diagnosed
If you are a patient with a newly diagnosed brain tumour, your doctor will start you
on a dose of ASTROMIDE every day for 42 days (up to 49 days) in combination with radiation
therapy. This is the first part of the treatment ("concomitant phase") in which you
complete the radiation therapy. Your treatment will be interrupted for 4 weeks to
give your body a chance to recover.
Then, you will start the next phase of treatment ("adjuvant phase") and your ASTROMIDE
dose will change. In this phase, there are up to 6 treatment cycles. Each treatment
cycle lasts 28 days. You will take your new dose of ASTROMIDE capsules once daily
for the first five days ("dosing days") of each cycle, followed by 23 days without
ASTROMIDE; this adds up to a 28 day treatment cycle. After day 28, the next cycle
will begin, in which you will again take this medicine once daily for five days followed
by 23 days without ASTROMIDE. Before each new treatment cycle begins, your blood will
be tested to determine if the ASTROMIDE dose needs to be adjusted.
If you are taking only ASTROMIDE (patients treated for recurrent brain tumour):
Take the dose the doctor has prescribed once a day for five days.
Depending on your response to ASTROMIDE, a new treatment cycle will begin each 28
days. You will then take this medicine again once daily for five days.
Before each new treatment cycle, your blood will be tested to see if the dose needs
to be changed.
How to take it
Each time you start a new treatment cycle, be sure you understand exactly how many
capsules of each strength you need to take on each day of dosing.
ASTROMIDE comes in different strength capsules (shown on the outer label in mg). Each
strength is a different colour. Depending on the dose of ASTROMIDE that your doctor
prescribes, you may have to take several capsules on each dosing day of the treatment

Ask your doctor or pharmacist to write down the number of each strength (include colour)
that you need to take on each dosing day.
Be sure you know exactly which days are your dosing days.

cycle. Sometimes the dose or the mix of capsules you need to take will be different
from the last cycle.
Once you take the medicine home, if you are confused or unsure about how to take your
dose, call for re-instruction before beginning the treatment cycle. Errors in how
you take this medicine may have serious health consequences
