What Testosterone Implants are used for

Testosterone Implants are used to treat confirmed testosterone deficiency in males.

The active substance of Testosterone Implants is testosterone. In men, testosterone is produced by the testicles. It is necessary for the normal growth, development and function of the male sex organs and for secondary male sex characteristics. It is also 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).

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.

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

Other medicines and Testosterone Implants
Please tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines – even those not prescribed.
Other medicines may influence the effects of Testosterone Implants, or Testosterone Implants may affect other medicines. Therefore you must tell your doctor or pharmacist if you are using, or are about to use:

  • Insulin and/or other medicines to control blood sugar levels;
  • Medicines to reduce the clotting of your blood (anti-coagulants);

The use of androgens like Testosterone Implants may lead to a reduction of the doses of these 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 Testosterone Implant 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 Testosterone Implants with food and drink
This medicine can be implanted without taking consideration of meals and drinks.

Pregnancy, breast-feeding and fertility
Testosterone Implants are not for use in women, therefore this medicine must not be taken by women who are pregnant or think that they are pregnant, or by women who are breast-feeding.

In men, treatment with Testosterone Implants can lead to fertility disorders by repressing sperm formation.

If you are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

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).

Additionally, at regular intervals, blood tests will be done to check the oxygen-carrying substance in your red blood cells (hemoglobin). In very rare cases the number of red blood cells will increase too much leading to complications.

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 Testosterone Implants can interfere with anti-doping testing.
