1. What Restandol Testocaps is and what it is used for

Restandol Testocaps are soft oval glossy capsules which contain 40 mg of testosterone undecanoate. The active substance, testosterone undecanoate is turned into testosterone by your body. Testosterone is a natural male hormone known as an androgen. It is produced in the body by both men and women.

Restandol Testocaps is used in adult men for testosterone replacement to treat various health problems caused by a lack of testosterone (male hypogonadism). This should be confirmed by two separate blood testosterone measurements and also include clinical symptoms such as impotence, infertility, low sex drive, tiredness, depressive moods, bone loss caused by low hormone levels.

Restandol Testocaps are used if your body does not make enough testosterone of its own, for example:

  • impotence caused by hormonal disorders
  • after castration or a similar problem called eunuchoidism
  • decreased sex drive and decreased mental and physical activity
  • certain types of infertility because you don’t make enough sperm

It may also be used to treat a type of bone disease (osteoporosis) caused by having too little testosterone.

2. What you need to know before you take Restandol Testocaps

  • Do not take Restandol Testocaps: If you are allergic (hypersensitive) to testosterone undecanoate or any of the ingredients of this medicine (listed in section 6 “What Restandol Testocaps contain”).
  • If you have or have had a tumour of your prostate or breast or are suspected to have one of these tumours.
  • If you have ever had liver cancer

Take special care with Restandol Testocaps:

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. In men over the age of 45, the prostate gland will be investigated 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 (haemoglobin). In very rare cases the number of red blood cells will increase too much leading to complications.

The following blood checks should be carried out by your doctor before and during the treatment: testosterone blood level, full blood count.

Medical check may also be necessary in some other conditions.

  • Tell your doctor if you have ever had, still have, or are suspected to have:
    • breast cancer which has spread to the bones
    • kidney or lung cancer
    • heart disease
    • kidney disease
    • liver disease
    • high blood pressure
    • diabetes mellitus
    • epilepsy
    • migraine, headaches
    • prostatic complaints, such as problems passing urine
    • blood clotting problems - thrombophilia (an abnormality of blood coagulation that increases the risk of thrombosis – blood clots in blood vessels)

If you are suffering from severe heart, liver or kidney disease, treatment with Restandol Testocaps may cause severe complications in the form of water retention in your body sometimes accompanied by (congestive) heart failure.

Tell your doctor if you have high blood pressure or if you are treated for high blood pressure as testosterone may cause a raise in blood pressure.

If you have sleep apnea (temporarily stopping breathing during your sleep), this 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.

  • Also tell your doctor
    • if you are taking anticoagulants (drugs to treat blood clots)

Your medication may need to be monitored more closely.

Children and adolescents

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

Extra supervision by the doctor is necessary in the treatment of children and adolescents since testosterone administration in general may cause early sexual development and limits growth (see section 4 “Children and adolescents”).

Other medicines and Restandol Testocaps

  • 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 affect how Restandol Testocaps works or Restandol Testocaps may affect how they work. Therefore you must tell your doctor or pharmacist if you are using or are about to use:

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

The following medicines may decrease the effect of Restandol Testocaps:

  • antibiotics such as rifampicin
  • anti-epileptic drugs such as barbiturates, carbamazepine, dichloralphenazone, phenylbutazone, phenytoin and primidone.

The use of androgens like Restandol Testocaps 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 Restandol Testocaps may increase the risk of water retention, especially if your heart and liver are not working properly.

Laboratory tests:

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.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Using Restandol Testocaps with food and drink

  • Therefore, Restandol Testocaps must be taken with a normal meal (see section 3).
