Testosterone injection and gel

About testosterone

Testosterone is produced by the testicles. It is known as an androgen - a male sex hormone. Testosterone is essential for the normal growth and development of the male sex organs and sexual characteristics. Where a man's natural testosterone levels are too low (a condition called male hypogonadism), testosterone is prescribed as replacement therapy. It can be prescribed as a gel which is applied to the skin or as an injection.

Before taking or using testosterone

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking/using testosterone it is important that your doctor knows:

• Om du har några problem med hur din lever fungerar, eller om du har några problem med hur dina njurar fungerar.

• If you have a heart condition or high blood pressure.

• If you have a condition called thrombophilia which affects the way your blood clots, or if you are at higher risk of blood clots for any other reason.

• If you have any of the following conditions: epilepsy, migraine, or diabetes.

• If you have a breathing problem while you are asleep called sleep apnoea.

• If you have cancer.

• Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take or use testosterone

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about the specific brand of testosterone you have been prescribed, and it will also provide you with a full list of the side-effects which you could experience.

• Take or use testosterone exactly as your doctor tells you to. Your dose will be on the label of the pack to remind you. The doses given below are intended to be a guide only.

• If you are having injections: these are given by your doctor or nurse, usually on a regular basis, so make sure you know when your next treatment is due.

• If you are using Testavan®, Testim®, Testogel® or Tostran® gels: apply the gel at about the same time each day, to a clean, dry area of your skin. The manufacturer's information leaflet will explain which areas of your skin the gel can be applied to - please read this carefully before you use the gel. Your doctor or pharmacist will explain to you how much gel you should use each time.

• If you miss a dose, read the manufacturer's information leaflet which comes with your treatment for advice on what to do.

• Please try to keep any routine appointments with your doctor. This is so your doctor can check on your progress.

• If you experience frequent or persistent erections, you must let your doctor know about this. Your dose may need to be adjusted or your treatment stopped for a while to avoid any injury.

• If you are using a gel, testosterone can be transferred to other people through close skin contact. This may cause side-effects in the other person. To prevent this from happening, cover the treated area with clothes or take a shower before you have close contact. It is very important that pregnant women avoid contact with any areas of your skin which have been treated with testosterone gel.

• Please be aware that testosterone preparations can interfere with anti-doping testing used in competitive sports.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with testosterone. You will find a full list in the manufacturer's information leaflet supplied with your medicine.
