What is PRIMOTESTON DEPOT used for and how does it work
PRIMOTESTON DEPOT contains a derivative of the natural male sex hormone testosterone (testosterone enanathate).
How does PRIMOTESTON DEPOT work?
PRIMOTESTON DEPOT can be considered an androgenic hormonal preparation that is it induces a masculinising effect such as that produced by the testis, ovaries and adrenal cortex.
After PRIMOTESTON DEPOT is injected into your muscle it is gradually released into the bloodstream thus allowing a time interval between injections. The effect of PRIMOTESTON DEPOT lasts approximately 2- 4 weeks but differs between individuals.
What is PRIMOTESTON DEPOT used for?
PRIMOTESTON DEPOT is used in men for conditions of hypogonadism (abnormal hormone secretion of the gonads); potency disorders; male climacteric (a stage of life similar to that of menopause in females which can lead to symptoms such as: fatigue, diminished sexual desire, erectile impotency) and aplastic anaemia (a condition resulting in an abnormal number of red blood cells).
In woman, PRIMOTESTON DEPOT is used as a supplementary therapy for progressive breast cancer during the postmenopausal period.

As a precaution, regular examinations of the prostate are recommended for men. If you are on long-term androgen therapy blood tests should be carried out on a regular basis.
How to use PRIMOTESTON DEPOT properly
Remember that PRIMOTESTON DEPOT has been prescribed for you personally. Do not share it with others.
When and how to administer PRIMOTESTON DEPOT
PRIMOTESTON DEPOT must be injected into the muscle. Short lasting reactions e.g. coughing urges, coughing fits or respiratory distress may occur in rare cases during or immediately after injection. To avoid this PRIMOTESTON DEPOT should be injected extremely slowly.
Dosage and administration for men
PRIMOTESTON DEPOT can be used in cases where androgen-dependant target organs (e.g. ovaries, testis and adrenal cortex) are still underdeveloped. This may aid in the development and stimulation of these organs.
250mg PRIMOTESTON DEPOT should be injected into the muscle every 2-3 weeks. To maintain an adequate effect, 250mg PRIMOTESTON DEPOT should be injected into the muscle every 3-4 weeks thereafter. Injection intervals may vary in certain instances.
Disorders of potency based on an androgen deficiency (a deficiency in hormone which has a masculinising effect) can be eliminated with administration of PRIMOTESTON DEPOT.
1 ampoule PRIMOTESTON DEPOT 250mg should be injected every 4 weeks. (An initial dose of 100mg PRIMOTESTON DEPOT, followed one week later with another 100mg injection can be given).
In this instance the diminished androgen production (frequent with onset of middle age) and its symptoms e.g. reduced performance, rapid fatigue, diminished memory and ability to concentrate, disorders of libido and potency, depressive moods, irritability, sleep disturbances and general vegetative complaints may be improved with administration of PRIMOTESTON DEPOT.
1 ampoule PRIMOTESTON DEPOT 250mg should be injected every 3-4 weeks. Repeated 6-8 week courses at 2-3 month intervals are recommended.
This condition results in an abnormal number of red blood cells in the blood. High doses of androgen such as PRIMOTESTON DEPOT promote erythropoiesis (formation of red blood cells).
250mg PRIMOTESTON DEPOT injected into the muscle 2-3 times per week.
Dosage and administration for women
Treatment with androgens such as PRIMOTESTON DEPOT cannot replace surgery or irradiation methods of cancer therapy.
Supplementary therapy of progressive breast cancer in postmenopause
Injection of 250mg PRIMOTESTON DEPOT into the muscle every 2 weeks has led to remissions in some cases. Other benefits of this type of therapy include pain relief, improved condition and mental stimulation.
In particular, PRIMOTESTON DEPOT has frequently shown a positive effect on bone metastases. To maintain this effect it may be necessary to shorten the time intervals between treatments.
PRIMOTESTON DEPOT is classified as non-toxic after single intake. Even in instances which require higher doses of PRIMOTESTON DEPOT no toxicity is to be expected.
When using PRIMOTESTON DEPOT

You are taking phenobarbital as this medication may decrease the effectiveness of PRIMOTESTON DEPOT.
You develop a blood clot, especially when taking medicines which contain coumarin derivatives at the same time as treatment with PRIMOTESTON DEPOT.
When you are using PRIMOTESTON DEPOT, your doctor will tell you to return for regular check-ups.
