Testim

Generic name: Testosterone Topical
Drug class: Androgens and anabolic steroids

Usage of Testim

Testosterone is a naturally occurring male hormone necessary for many processes in the body.

Testim (for the skin) is used to treat conditions in men that result from a lack of natural testosterone.

Testosterone will not enhance athletic performance and should not be used for that purpose.

Testim may also be used for purposes not listed in this medication guide.

Testim side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Testim may cause serious side effects. Stop using Testim and call your doctor at once if you have:

increased urination (many times per day), loss of bladder control;

painful or difficult urination;

breast pain or swelling;

painful or bothersome erections;

swelling, rapid weight gain, shortness of breath during sleep;

chest pain or pressure, pain spreading to your jaw or shoulder;

signs of a blood clot in the lung--chest pain, sudden cough, wheezing, rapid breathing, coughing up blood; or

signs of a blood clot deep in the body--swelling, warmth, or redness in an arm or leg.

Topical testosterone is absorbed through the skin and can cause side effects or symptoms of male features in a child or woman who comes into contact with Testim. Call your doctor if a person who has close contact with you develops enlarged genitals, premature pubic hair, increased libido, aggressive behavior, male-pattern baldness, excessive body hair growth, increased acne, irregular menstrual periods, or any signs of male characteristics.

Common side effects of Testim may include:

redness, itching, burning, hardened skin or other irritation where the medicine was applied or where the skin patch was worn;

increased red blood cells (may cause dizziness, itching, redness in your face, or muscle pain);

increased prostate-specific antigen;

increased blood pressure;

headache;

mood changes, strange dreams;

frequent or prolonged erections;

nausea, vomiting; or

swelling in your lower legs.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before taking Testim

You should not use Testim if you are allergic to testosterone patches or gels, or if you have;

prostate cancer; or

male breast cancer.

Tell your doctor if you have ever had:

breast cancer or prostate cancer;

enlarged prostate, urination problems;

heart problems;

a heart attack, stroke, or blood clot;

sleep apnea (breathing stops during sleep); or

liver or kidney disease.

The testosterone transdermal patch may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test.

Using testosterone may increase your risk of developing prostate cancer. Ask your doctor about this risk.

Testosterone can lower your sperm count and may affect fertility (your ability to have children).

This medicine should not be used by a woman. Testosterone may harm an unborn baby. A pregnant woman should avoid coming into contact with Testim patches or gels, or with a man's skin areas where a patch has been worn or the gel has been applied. If contact does occur, wash with soap and water right away.

Do not use Testim on anyone younger than 18 years old.

Different brands of testosterone topical have different instructions for use. Not every brand of this medicine is used on the same skin areas. Some brands are applied to the shoulder, upper arm, or stomach. Other brands are applied to the thighs or to the underarms. Carefully follow the patient instructions provided with your medicine.

Wash your hands with soap and water before and after applying testosterone transdermal.

Apply testosterone gel to dry skin after showering or bathing. Allow the medicine to dry for at least 5 minutes before you dress.

Testosterone gel is flammable. Do not use near high heat or open flame. Do not smoke until the gel has completely dried on your skin.

Cover treated skin areas with clothing to keep from getting this medicine on other people. If someone else does come into contact with a treated skin area, they must wash the contact area right away with soap and water.

Keep each skin patch in the foil pouch until you are ready to use it. Do not use a skin patch that has been cut or damaged.

Apply the transdermal skin patch to a flat, clean, dry, and undamaged area of skin on your back, stomach, upper arm, or thigh. Wear the patch for 24 hours and then replace it with a new patch. Choose a different skin area each time you put on a new patch. Do not use the same skin area twice in a 7-day period.

You may need frequent blood tests.

Store at room temperature. Do not freeze. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.

After removing a skin patch, fold it closed with the sticky side in, and throw it away. Place used patches and empty testosterone tubes in a trash container that pets and children cannot get to.
