What Testogel is used for and how it works
Testogel is used to replace the body’s natural hormone testosterone when not enough is made by the body.
Testosterone is a natural male hormone, known as an androgen, which controls normal sexual development in men.
Testosterone is essential for the development and maintenance of the male reproductive organs as well as other male characteristics, such as deep voice, increased muscle strength, hair growth etc.
Testogel is a testosterone-containing gel that is applied by the patient daily to the skin. The testosterone passes from the gel through the skin and into the bloodstream at a steady rate.
The testosterone in Testogel is identical to the naturally occurring testosterone present in the body.
Your doctor may prescribe Testogel for other reasons. Ask your doctor if you have any questions about why Testogel has been prescribed for you.
A doctor’s prescription is required to obtain this medicine.
This medicine is not addictive.

Before you start to use Testogel
Tell your doctor if you have, or have had, any of the following medical conditions:
high blood pressure or heart problems
a tendency to retain fluid (signs may include swollen feet or ankles)
liver or kidney disease
any form of cancer
high levels of calcium in the blood (hypercalcaemia)
high levels of calcium in the urine (hypercalciuria)

Testogel may increase the risk of benign prostatic hypertrophy (enlargement of the prostate gland) and/or prostate cancer. It may also increase the risk of breast cancer. During treatment, your doctor may monitor the effects of this medicine on the prostate gland and the breast.
Worsening of breathing problems during sleep has been reported during treatment with testosterone replacement in predisposed people. This is especially true in overweight people or people with lung problems.
People using testosterone replacement over long periods of time may develop polycythaemia (an abnormal increase in the number of red blood cells in the blood). Your doctor may organise regular blood tests to check this is not happening.
Sportsmen and women
Athletes should note that the active substance, testosterone, may produce a positive reaction in anti-doping tests.

Also tell any doctor or dentist who prescribes another medicine for you that you are using Testogel.

How to use Testogel
How much to use
The usual starting dose is one 5 g sachet of gel per day. Your doctor or pharmacist will tell you exactly how much to use. You should not use more than 10 g of gel per day.
How to use it
Testogel is for use by adult men only.
Do not apply Testogel to the testes, scrotum or penis. The high alcohol content may cause local irritation.
Follow these steps when applying Testogel:
1. Open the sachet(s)
2. Spread a thin layer of Testogel onto clean dry healthy skin over the upper arms, shoulders or stomach.
3. Allow the gel to dry for at least 3-5 minutes before dressing.
4. Wash your hands thoroughly with soap and water after applying the gel.
5. Cover the application area with clothing once the gel has dried.
6. Do not shower for at least six (6) hours after applying Testogel.
When to use it
Apply Testogel once per day at approximately the same time each day, preferably in the morning. Using it at the same time each day helps maintain a steady level of testosterone in the blood. It will also help you remember when to apply it.
How long to use it
Testogel helps control the symptoms of your condition, but does not cure it. Therefore you must use Testogel every day.
When you have finished a pack, start the next pack on the following day. Never leave a break between packs.
Continue using Testogel for as long as your doctor tells you to.
If you forget to use it
If you forget to apply a dose, apply it as soon as you remember.
If you do not remember to apply the dose until the next dose is due, then just apply one dose. Do not apply a double dose to make up for a forgotten individual dose.
If you use too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26) if you think you or anyone else may have used too much Testogel.
While you are using Testogel
Things you must not do
Do not give Testogel to anyone else, even if they have the same condition as you.
Do not stop using Testogel, or change the dosage, without checking first with your doctor.
Things to be careful of
Testosterone may be transferred to another person during close and relatively prolonged skin contact with the gel application area. If contact occurs a number of times or for long periods of time this could cause the other person to show signs of increased testosterone such as more hair on the face and body and a deepened voice. In women, this may also cause changes in the menstrual cycle.
Unwanted transfer of testosterone to another person can be avoided by wearing clothes which cover the application area and/or by showering before contact.
You need to make sure that your partner is not put at risk of receiving testosterone by accident. You should leave a gap of 6 hours between applying Testogel and having intimate physical contact. You should also wear clothing such as a T-shirt to cover the gel application area and/or have a shower or bath beforehand.
You should also follow these precautions before coming into close contact with children.
If a woman or child does come into contact with Testogel, thoroughly wash the area of skin exposed to the gel with soap and water.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Testogel. Ask your doctor or pharmacist to answer any questions you may have. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.

Headaches, dizziness, ‘pins and needles’
