What Sustanon is used for

Sustanon is used to treat confirmed testosterone deficiency in males.

The active substances of Sustanon are turned into testosterone by your body.

Testosterone is the natural male hormone known as an androgen. In men, testosterone produced by the testicles. It is necessary for the growth, development and function of the male sex organs and for secondary male sex characteristics. It is necessary for the growth of body hair, the development of bones and muscles, and it stimulates the production of red blood cells. It also makes men’s voices deepen. Preparations containing testosterone are used to replace testosterone in a person who has low or no natural testosterone (a condition known as hypogonadism).

Your doctor may have prescribed it for another reason.

Ask your doctor if you have any questions about why this medicine has been prescribed to you.

A doctor’s prescription is required to obtain this medicine.

This medicine is not expected to affect your ability to drive a car or operate machinery.

Before you use Sustanon

When you must not use it

Do not use Sustanon if

  • If you have or have had a tumour of your prostate or breast or are suspected to have one of these tumors.
  • In children under the age of 3 years.
  • you have high levels of calcium in the blood (hypercalcaemia) or high levels of calcium in the urine (hypercalciuria)
  • If you are allergic to one or more of the ingredients of the product.
  • you are allergic to peanuts or soya.

Sustanon is for use by boys or men only.

Do not give Sustanon to women, especially if pregnant or breast-feeding. It may give increased male characteristics to an unborn baby.

There is not enough data available for the safe use of Sustanon during lactation.

Before you start to use it

Tell your doctor or pharmacist if you had, still have or are suspected to have any of the following medical conditions:

  • Breast cancer which has spread to the bones;
  • Kidney or lung cancer;
  • heart disease
  • kidney disease
  • liver disease
  • High blood pressure;
  • Clotting disorder
  • Diabetes mellitus
  • Epilepsy;
  • Migraine, headaches;
  • prostatic complaints (such as problems with passing urine).

If you have sleep apnoea (temporarily stopping breathing during your sleep), it may get worse if you are using testosterone-containing products. Let your doctor know if you are worried about this.

Extra supervision by your doctor may be necessary in case you are overweight or suffer from chronic lung disease.

Treatment with male hormones like testosterone may increase the size of the prostate gland, especially in elderly men. Therefore your doctor will examine your prostate gland at regular intervals by digital rectal examination (DRE) and blood tests for prostate-specific antigen (PSA).

Children and adolescents

The safety and efficacy of this medicine has not been adequately determined in children and adolescents.

Extra supervision by your doctor is necessary in the treatment of children and adolescents since testosterone administration in general may cause early sexual development and limits growth.

Sustanon should not be given to children under 3 years of age. This is because Sustanon contains benzyl alcohol, which may cause toxic or allergic reactions in infants and children up to 3 years old.

Improper use

If you are a patient who participates in competitions governed by the World Anti-Doping Agency (WADA), then you should consult the WADA-code before using this medicine as Sustanon can interfere with anti-doping testing.

Misuse of androgens to enhance ability in sports carries serious health risks and is discouraged.

Taking other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and Sustanon may interfere with each other. These include:

  • anticoagulants or medicines used to prevent blood clots
  • anti-diabetic medicines such as insulin used to treat diabetes and/or other medicines to control blood sugar levels.

The use of androgens like Sustanon may lead to a reduction of the doses of these medicines.

These medicines may influence the effects of Sustanon or Sustanon may affect other medication. You may need different amounts of your medicines, or you may need to take different medicines.

Also tell your doctor or pharmacist if you are using or about to use the hormone ACTH or corticosteroids (used to treat various conditions such as rheumatism, arthritis, allergic conditions and asthma). The use of androgens like Sustanon may increase the risk of water retention especially if your heart and liver are not working properly.

Androgens may also affect the results of some laboratory tests (e.g. thyroid gland). Therefore you must tell your doctor or the laboratory staff performing the tests that you are using this medicine.

Using Sustanon with food and drink

This medicine can be injected without taking consideration of meals and drinks.
