Driving and using machines
Your ability to drive or operate machines may be
influenced in case of nausea and vomiting. If you are
affected in this way do not drive or operate machines.

3. How you are given Treosulfan Injection
Treosulfan will be given to you by a drip given into a vein
over 15 to 30 minutes (intravenous infusion) in a dose
which is fixed by a doctor individually for you.
For single use only.

The effect of ibuprofen/chloroquine treatment may be
reduced when given in combination with treosulfan.

Your doctor will calculate your treosulfan dose on the basis
of your blood counts measured. Your doctor will reduce
the dose if other anticancer medicines or radiotherapy
have been given. The dose you are given also depends on
your size and varies with your body surface area (BSA).
Technically, this is measured in square metres (m²), but
actually is worked out from your height and weight. Usual
doses for treosulfan alone are 6-8 g/m² BSA. In combination
with cisplatin, treosulfan is usually dosed at 5 g/m² BSA.

It is not advisable to use any medicines without telling your
doctor as there may be interactions between treosulfan
and other medicines.

During the course of treosulfan therapy the infusions will
usually be given every 3 to 4 weeks. In general, 6 courses
of treatment are given.

Pregnancy and breast-feeding
Do not use treosulfan if you are pregnant or breastfeeding
unless your doctor considers it as absolutely necessary.
You must use effective contraception during therapy,
e.g. birth control pill.

Your doctor may change the dose and frequency of dosing
depending on your blood tests, your general condition,
further therapies and your response to treosulfan. If you
have any questions about your treatment, ask your doctor,
nurse or hospital pharmacist.

If you are planning to become pregnant or thinking of
breast-feeding discuss it with your doctor first.

If you experience pain at the site of injection, please tell
your doctor or nurse immediately.

recently taken or might take any other medicines.

Following these instructions, the whole reconstitution
procedure should take no longer than 2 minutes.

Instructions for reconstitution of Treosulfan Injection
To avoid solubility problems during reconstitution the
following aspects should be regarded.
1. The solvent, water for injection, is warmed to 25 - 30 °C
(not higher!) by using a water bath.
2. The treosulfan is carefully removed from the inner
surface of the infusion bottle by shaking.
This procedure is very important, because moistening
of powder that sticks to the surface results in caking.
In case caking occurs the bottle has to be shaken long
and vigorously.
3. One side of the double sided cannula is put into the
rubber stopper of the water bottle. The treosulfan bottle
is then put on the other end of the cannula with the
bottom on top.
The whole construction is converted and the water let run
into the lower bottle while the bottle is shaken gently.
