1. What Testosterone Enantate is and what
it is used for
Testosterone Enantate is a manufactured version of the naturally
occurring male sex hormone, testosterone.
It 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.

2. What you need to know before you use
Testosterone Enantate
Do not use Testosterone Enantate:
• if you are allergic to Testosterone Enantate or any of the other
ingredients of this medicine (listed in section 6)
• if you suffer from androgen (steroid hormone) dependent prostate
cancer or breast cancer
• if you have high calcium levels in your blood
• if you have or have had tumours of the liver
• if you have kidney disease (nephrosis)
Warnings and precautions
Talk to your doctor before using Testosterone Enantate if you:
• have liver problems including severe upper abdominal complaints
• have a tendency to retain fluid causing, for example, swelling of
the ankles
• suffer from sleep apnoea (interrupted breathing during sleep), as
this may get worse

• are suffering from severe heart, liver or kidney disease; treatment
with Testosterone Enantate may cause severe complications in the
form of water retention in your body sometimes accompanied by
(congestive) heart failure
• have high blood pressure or if you are being treated for high blood
pressure as testosterone may cause a rise in blood pressure
• have or have ever had blood clotting problems; thrombophilia
(an abnormality of blood coagulation that increases the risk of
thrombosis - blood clots in blood vessels)
• have epilepsy, migraine, diabetes mellitus or cancerous bone
disease.
Testosterone Enantate should not be used in women because they
may develop signs of virilisation, e.g. acne, increased hair growth on
the face or body and voice changes.
Male hormones such as Testosterone Enantate are not suitable for
increasing muscular development in healthy people or for increasing
physical ability.
Medical examination/consultation
Male hormones may increase the growth of prostate cancer and
enlarged prostate glands (benign prostatic hypertrophy). Before your
doctor injects Testosterone Enantate, s/he will examine you to check
that you do not have prostate cancer. If you are older, you may be at
an increased risk for the development of prostate enlargement when
using Testosterone Enantate. Although there is no clear evidence
that sex hormones such as Testosterone Enantate actually generate
cancer of the prostate, they can enhance the growth of any existing
cancer of the prostate.
As a precaution, regular examinations of the prostate are
recommended in men, especially if you are elderly.
If you are on long-term androgen therapy blood tests should be
carried out periodically (see section “Possible side effects”).
The following blood checks should be carried out by your doctor
before and during the treatment:
• testosterone blood level and
• full blood count
Following the use of hormonal substances such as androgen
compounds, cases of benign (non-cancerous) and malignant

(cancerous) liver tumours have been observed to occur. Although it
is improbable that a tumour will occur, these would present a health
concern. In isolated cases, internal bleeding could occur from these
tumours, which might endanger life.
Thus you should always seek the immediate emergency attention of
a doctor when you suffer severe abdominal pains. Not all unusual
sensations you might feel in your upper abdomen can be counted as
a possible sign of tumour or bleeding. Those that do not disappear
within a short time should however better be brought to your doctor's
attention.
Additional information on special populations
Children and adolescents
Testosterone Enantate is not indicated for use in children and
adolescents (see “Warnings and precautions”).
In children and adolescents, earlier development of male secondary
sex characteristics (masculinisation) may occur. Testosterone can
affect bone growth and in some cases reduce final height.
Safety and efficacy have not been adequately determined in children
and adolescents.
Elderly patients (65 years or older)
Limited data do not suggest the need for a dosage adjustment in
elderly patients (see “Warnings and precautions”).
Patients with impaired liver function
No formal studies have been performed in patients with liver
impairment. The use of Testosterone Enantate is contraindicated in
men with past or present liver tumours (see “Do not use Testosterone
Enantate”).
Patients with impaired kidney function
No formal studies have been performed in patients with kidney
impairment.
Other medicines and Testosterone Enantate
Tell your doctor or pharmacist if you are taking, have recently taken,
or might take any other medicines.
In particular, tell your doctor if you are having any of the following as
they may be affected or affect Testosterone Enantate:
