How to use ZOMACTON
ZOMACTON is injected under the skin (sub-cutaneous) by use of a needle or the ZOMAJET
needle-free administration device, which is supplied separately. It is important
to use a different site every day to prevent wasting of skin fat at the injection
Your doctor, nurse or pharmacist will tell you how many milligrams (mg) of ZOMACTON
your child must use each day.
It is very important that your child uses ZOMACTON exactly as instructed.
ZOMACTON should be used in the evening if possible. Normally, growth hormone is made
by the body at night. Giving the injection at night helps to copy this process.
Allow the product to warm to room temperature before injecting and check for cloudiness.
If cloudy do not use.
Tell your doctor, nurse or pharmacist if your child forgets to use ZOMACTON. Do not
use a double dose to make up for the dose that has been missed.
Do not stop using ZOMACTON without your doctor's permission. Missing injections can
reduce effectiveness and you risk being taken off growth hormone altogether.
The growth hormone is supplied in a powder form that must be prepared for injection
by mixing it with a diluent (a liquid in which it can be mixed for injection) before
use. For ZOMACTON 10 mg, use the entire contents of the pre-filled solvent syringe
to reconstitute the powder for injection.
Once you have reconstituted the growth hormone with the diluent, it is ready for injection.
Each reconstituted vial contains a preservative and enough medication for several
You will be taught to mix and inject ZOMACTON using needles or the ZOMAJET needle-free
administration device. It is a good idea to refer to the instruction sheet you receive
each time you mix and inject.
The ZOMAJET Vision X is for use with ZOMACTON 10 mg. Each device is supplied with
3 heads in different sizes that are labelled A, B and C. Detailed instructions for
choosing the correct head, self-injecting and evaluating your injection technique
come with the ZOMAJET needle free device. If you experience problems using the ZOMAJET
device, contact your nurse or physician.
