This medicated solution contains testosterone. It is used for hormone replacement in men who are not able to produce enough testosterone (hypogonadism). This medication is absorbed through the skin, enters your bloodstream, and helps your body reach normal testosterone levels.

Testosterone helps the body to develop and maintain the male sexual characteristics (masculinity), such as a deep voice and body hair. It also helps to maintain muscle and prevent bone loss, and is necessary for natural sexual ability/desire.

Women should not use this drug.

Read the Medication Guide provided by your pharmacist before you start using testosterone solution and each time you get a refill. Learn how to use the pump and how to apply the solution correctly. If you have any questions, ask your doctor or pharmacist.

There are many testosterone products available for use on the skin. They may have different amounts of testosterone and may not have the same effects. Read the dosing instructions carefully for each product. Do not change products without asking your doctor or pharmacist.

Follow the instructions for priming the pump if you are using it for the first time.

Avoid applying this medication to broken, irritated skin. After applying, do not rub in the solution with your fingers or hand. If your dose requires you to apply more medication to the same armpit, wait for the medication to dry before applying more medication. Do not apply this medication to other areas of the body, including the genitals (penis or scrotum).

The dosage is based on your medical condition, lab tests, and response to treatment. Follow your doctor's instructions carefully on the exact number of pumps for each dose.

Wait a few minutes for the application site to dry completely before dressing. Be sure to always wear clothing (such as a t-shirt) to cover the application site until you wash the areas well with soap and water. To get the best effect, wait at least 2 hours before showering/swimming to allow the drug to be absorbed through the skin.

After applying this medication, rinse the applicator cup with running water and then pat dry with a tissue. Replace the applicator and cap back onto the bottle. Wash your hands thoroughly with soap and water.
