HOW TO MAKE UP THE MEDICINE
USING YOUR MEDICINE
The doctor will calculate the precise dose of drug you require,
according to your weight. The maximum recommended dosage
is 0.27 mg per kg bodyweight, per week.
This weekly amount may be divided into seven doses with one
dose each day. The dose is administered subcutaneously with a
syringe, with the needle-free ZomaJet 2 Vision or with the
needle device Ferring Pen. Your doctor will have given you
dosage instructions and told you which method of
administration to use.
In the event of a missed dose, do not worry. Carry on as usual
and administer the next dose at your usual time.
An overdose may cause hypoglycaemia (low blood sugar), followed by hyperglycaemia (high blood sugar). In the event of an
overdose, contact the doctor or nearest hospital casualty department at once. The e ects of repeated overdosing are unknown.
If you miss a dose for any reason, you may experience hypoglycaemia (low blood sugar level). Although the long-term e ectiveness of the treatment will not be a ected, you should consult
your doctor if this happens.
Disturbances in blood sugar, including diabetes mellitus have
been observed. Very rare cases of leukaemia have been reported,
but it appears to be no more common than in children not treated
with growth hormone.
The subcutaneous administration of growth hormone may lead
to an increase or decrease of fat at the site of administration. It
is therefore recommended to frequently change the site of
administration. On rare occasions, patients develop pain and an
itchy rash at the site of administration.
If you experience any incidence of blistering, bruising or abscess
(redness, swelling, pain, heat, boil formation) following the use
of the ZomaJet 2 Vision, please inform your doctor.
Transient headache has been reported during growth hormone
replacement therapy. Rarely, a slight transient oedema (swelling
may occur during treatment with
due to the build up of
In some cases, especially during the rst few weeks of therapy,
repeated or prolonged headache, nausea and/or vomiting and
visual problems may occur.
If these or any other undesirable e ects are experienced, please
inform your doctor.
