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. It is the natural male hormone produced by the testicles, 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 for the production of red blood cells. It
also makes men's voice 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.
This medicine is not expected to affect your ability to drive a car or operate machinery.
Before you use Testosterone Implants
When you must not be given it
You have or have had a tumour of your prostate or breast
You are allergic to the active ingredient testosterone.
Before you are given it
Tell your doctor if you have or have ever had any of the following medical conditions:
heart disease
kidney disease
liver disease
high blood pressure
prostatic complaints such as problems passing urine
If you have sleep apnoea (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 a doctor is necessary in the treatment of young boys.
This is because testosterone administration may cause early sexual development and disturb normal growth.
Extra supervision by a doctor is also necessary in elderly men.
This is because male hormones may increase the size of the prostate gland.
Misuse of androgens to enhance ability in sports carries serious health risks and is discouraged.

Using Testosterone Implants
How much to use
The dose is chosen by your doctor. Usually in men a dose of 600 - 1200 mg testosterone is given, depending on individual requirements.
In most hypogonadal men, a dose of 800 mg maintains the plasma testosterone levels within the normal male physiological range.
The implants are effective for approximately 4 - 5 months.
How the implant is inserted
This medicine should only be given by a doctor or nurse.
Testosterone Implants are inserted under the skin (for example at the lower abdominal wall or buttock) to facilitate removal
should it be necessary. A local anaesthetic is given in the area of implantation before the implants are inserted and the
small cut made is dressed with a bandage afterwards.
Dosage should be adjusted by your doctor in response to individual requirements.
If you are given too much (overdose)
Testosterone Implants are given under medical supervision and it is very unlikely that you will be given too much.
You should consult your doctor if you feel the effect of the Testosterone Implants are too strong or too weak as side-effects
are dependent on dosage, dose interval and your individual sensitivity.
While you are using Testosterone Implants
Keep all of your appointments so that your progress can be checked.
Your doctor may do some blood tests at regular intervals to make sure the medicine is working and to prevent unwanted side
effects.
As far as known, Testosterone Implants have no adverse effects on alertness and concentration.
