3. How
Desferrioxamine Mesilate Powder for Injection is used
The dose of
medicine given to you will depend on your medical
condition, your age and how well your kidneys are
working:
Acute iron poisoning:
Treatment with desferrioxamine mesilate both by mouth
and by injection or infusion (very slow injection) may
be required.Treatment may be repeated until iron levels
are brought back down to normal levels.
Conditions arising from gradual
build up of iron, e.g. thalassaemia: Dosage is
determined by assessment of the levels of excess iron in
the body. Treatment is usually given by infusion.
Treatment may need to be repeated on a daily basis in
some cases.
Aluminium overload due to kidney
failure: Such patients will already receive
dialysis treatment. Desferrioxamine mesilate is given
once a week usually by infusion linked to the time of
their dialysis.
Diagnosis of conditions associated
with iron overload: The amount of iron in the
urine following an injection of desferrioxamine mesilate
can be used to diagnose certain iron overload
conditions.
Diagnosis of aluminium overload:
The difference in the amount of aluminium in the
bloodstream before and after a slow injection of
desferrioxamine mesilate into a vein may help diagnose
aluminium overload in certain patients with kidney
failure.
This
medicine will be diluted with Water for Injections and
may be further diluted with glucose solution, sodium
chloride solution or a mixture of glucose and sodium
chloride solution before it is given to you. It will be
given either as an injection under the skin; in to a
vein; in to a muscle or in to the cavity of the abdomen
OR may be given as an oral solution.
If it is
given under the skin or into a vein, it is usually given
as a slow injection via a drip (infusion).
As this
medicine will be given to you whilst you are in hospital
is unlikely that you will be given too little or too
much, however, tell your doctor or pharmacist if you
have any concerns.
