What ZOMACTON is used for

ZOMACTON is a growth hormone. The active ingredient is somatropin.

ZOMACTON is used for the long-term treatment of children who have growth failure due to a low secretion of natural human growth hormone.

It should not be used in adults.

Ask your doctor if you have any questions about why this medicine has been prescribed. Your doctor may have prescribed ZOMACTON for another purpose.

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 site.

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 doses.

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, selfinjecting 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.

While you are using ZOMACTON

Tell your doctor, nurse or pharmacist if you have any concerns while your child is using ZOMACTON.

Things you must do

Speak to your doctor or pharmacist before use if you have concerns about how the product looks e.g. if it looks different from normal.

After mixing, check to make sure that the powder is completely dissolved and the solution is clear. You can assist the powder to dissolve by using a slow swirling motion. However, do not shake as this may deactivate the growth hormone.

Things you must not do

ZOMACTON should be used strictly according to the instructions you have been given. Do not change the dose unless your doctor has told you to.

You must not miss injections regularly.

Do not heat or freeze your mixed or unmixed ZOMACTON.

Do not give your ZOMACTON to anyone else.

Things to be careful of

The instructions for mixing the ZOMACTON powder must be followed exactly otherwise problems such as the following may occur:

  • loss of ZOMACTON activity
  • broken or jammed administration device.

If any of these problems occur contact the person who trained you on how to mix your ZOMACTON.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription. In particular, tell your doctor if you are taking:

  • any medicine for the treatment of diabetes
  • thyroxine (thyroid hormone) for the treatment of thyroid deficiency
  • corticosteroids such as cortisol or dexamethasone e.g. for the treatment of severe asthma, some skin conditions or rheumatoid arthritis
