Indications & Uses
In males, Testosterone Decanoate is used as replacement therapy for primary and secondary hypogonadal disorders. These include the following: after castration, eunuchoidism, hypopituitarism, endocrine impotence, certain types of infertility due to spermatogenic disorders, male climacteric symptoms such as decreased libido and a decreased feeling of general wellbeing and fitness, and osteoporosis caused by androgen deficiency. In female to male transsexuals, Testosterone Decanoate is used for masculinization.
Pharmacology
Testosterone is the main hormone the male body makes naturally. It is needed for the normal growth and development of the male sex organs and the male secondary sex characteristics. In adult life it is still needed for the testes and their accessory structures to work properly. It also helps maintain libido, sense of well-being, erectile potency, and the function of the prostate and seminal vesicles.
When men with hypogonadism are treated with Testosterone Decanoate, the plasma concentrations of testosterone, dihydrotestosterone and androstenedione rise by a clinically significant amount, and SHBG (sex hormone binding globulin) falls. In males with primary (hypergonadotropic) hypogonadism, Testosterone Decanoate brings gonadotropin levels back to normal. In female-to-male transsexuals, treatment with Testosterone Decanoate causes a clinically significant rise in plasma testosterone, and LH, FSH and SHBG levels all fall.
Dosage Reference
Reference Information Only
Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.
Adults:
The dose of Testosterone Decanoate should be adjusted to suit the response of each patient.
Adults: one injection of 1 ml every three weeks is usually enough. Give testosterone by deep intramuscular injection.
Children: safety and efficacy have not been properly established in children and adolescents. Testosterone contains benzyl alcohol, so it should not be given to children under 3 years of age.
Side Effects
Testosterone Decanoate most often causes the following side effects: precocious sexual development, more frequent erections, enlargement of the penis, premature closure of the epiphyses (the growing ends of the bones), priapism, oligospermia, a smaller volume of ejaculate, and retention of fluid and sodium.
Cautions & Contraindications
Warnings & Precautions
Be careful when giving Testosterone Decanoate, or any androgen, to boys who haven't yet reached puberty. It can close the growth plates of the bones too early (premature epiphyseal closure) or bring on sexual development far earlier than normal (precocious sexual development). Skeletal maturation should be checked regularly. People who have latent or overt cardiac failure, renal dysfunction, hypertension, epilepsy or migraine, or who have had any of these in the past, need close medical supervision. The condition can sometimes get worse or come back. Use androgens with caution in men who have benign prostatic hyperplasia. Steroids may also change the results of certain laboratory tests. Androgens are sometimes misused to improve performance in sports. This carries serious health risks and should be discouraged.
Contraindications
Testosterone Decanoate must not be used by anyone who is known to be hypersensitive to testosterone or to any of the other components in the product. It is also contraindicated in men who have known or suspected prostatic carcinoma or breast carcinoma.
Pregnancy & Breastfeeding
Pregnancy: There isn't enough data on the use of Testosterone in pregnant women. Because it can cause virilization of the foetus, Testosterone Decanoate should not be used during pregnancy. If a woman becomes pregnant, the treatment should be stopped.
Lactation: There isn't enough data on its use during lactation either, so Testosterone should not be used while breastfeeding.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
Overdose
Testosterone Decanoate has very low acute toxicity when it's given by intramuscular injection. Priapism in men is a sign of long-term overdosage. If it happens, stop the treatment, and once the symptom has gone, restart at a lower dose.
⚠️ In an emergency call 999 or go to the nearest hospital emergency department.
Storage
Keep Testosterone Decanoate in a cool, dry place where the temperature stays between 8º C and 30º C, and protect it from light. Keep it out of the reach of children.
