Testosterone Topical (patient information)

# Why is this medication prescribed
Testosterone topical gel is used to treat the symptoms of low testosterone in men who do not produce enough natural testosterone. Testosterone is a hormone that is usually produced by the body that is needed for the growth and functioning of the male sexual organs and for the development of typical male characteristics. Symptoms of low testosterone include decreased sexual desire and ability, extreme tiredness, low energy, depression, brittle bones that may break easily, and loss of certain male characteristics such as muscular build and deep voice. Testosterone gel works by supplying testosterone to replace the testosterone that is normally produced in the body.

# How should this medicine be used
Topical testosterone comes as a gel to apply to the skin. It is usually applied once a day. It is best to apply testosterone gel in the morning. To help you remember to use testosterone gel, use it at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use testosterone gel exactly as directed. Do not apply more or less of it or apply it more often than prescribed by your doctor.
AndroGel  and Testim brand gels both contain testosterone, but they are manufactured differently and are used in slightly different ways. Be sure that you know which brand of gel you are using and how and where you should apply it. Read the manufacturer's patient information that came with your gel carefully.
You can apply AndroGel anywhere on your shoulders, upper arms, or abdomen (area between your chest and your waist). You can apply Testim anywhere on your shoulders or upper arms, but you should not apply it to your abdomen. You should not apply either gel to your penis or scrotum or to skin that has sores, cuts, or irritation.
Be careful not to get testosterone gel in your eyes. If you do get testosterone gel in your eyes, wash them right away with warm, clean water. Call a doctor if your eyes become irritated.
You should not shower, bathe, swim, or wash the place where you applied the medication for at least 2 hours after you apply Testim gel or at least 5-6 hours after you apply AndroGel . Once in while, you may shower, bathe or swim as soon as 1 hour after you apply AndroGel , but you should usually wait the full 5-6 hours. If you usually take a bath or shower in the morning, be sure to take your bath or shower before you apply either brand of testosterone gel.
Testosterone gel comes in single use tubes and packets and a multiple use pump. The pump releases a specific amount of testosterone gel each time the top is pressed. You will probably need to press the top of the pump four to eight times to get your full dose of testosterone gel. Your doctor or pharmacist will tell you how many times to press the pump for each dose, and how many doses your pump contains. Throw away the pump after you have used that number of doses even if it is not empty.
Testosterone gel may catch fire. Stay away from open flames and do not smoke while you are applying testosterone gel and until the gel has dried completely.
Your doctor may start you on a low dose of testosterone gel and gradually increase your dose, not more than once every two weeks.
Testosterone gel may control your condition but will not cure it. Continue to use testosterone gel even if you feel well. Do not stop using testosterone gel without talking to your doctor. If you stop using testosterone gel, your symptoms may return.
To use testosterone gel, follow these steps:
- Be sure that the skin in the place where you plan to apply testosterone gel is completely dry.
- Open your container of testosterone gel. If you are using a packet, fold the top edge at the perforation and tear across the packet along the perforation. If you are using a tube, unscrew the cap. If you are using a pump for the first time, press down on the top of the pump three times and discard the medication that comes out down a drain or in a trash can that is safe from children and pets.
- Squeeze the packet or tube or press down on the top of the pump the right number of times to place the medication on the palm of your hand. It may be easier to apply testosterone gel if you squeeze the medication onto your palm and apply it to your skin in small portions.
- Apply the medication to the area you have chosen.
- Throw away the empty packet or tube in a trash can that is safe from children and pets.
- Wash your hands with soap and water right away.
- Allow the medication to dry for a few minutes before you cover the area with clothing.
