This medicated gel contains testosterone. It is used for hormone replacement in men who are not able to produce enough testosterone (for example, due to 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.
This drug should not be used by women.
Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using testosterone gel and each time you get a refill. 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.
If you are using the gel pump, learn how to prepare the pump for use. You may pump this medication into the palm of your hand or directly onto the desired application site. If you are not sure how to use the pump, ask your pharmacist.
Apply the medication as directed to clean, dry skin of the shoulders/upper arms as directed by your doctor, usually once daily in the morning. Apply only to areas that would be covered if you were to wear a short sleeve t-shirt. Certain brands of this medication may also be applied to the stomach area (abdomen). Check your product's instructions or ask your pharmacist if your brand may be applied to the abdomen. Avoid applying this medication to broken, irritated skin. Do not apply to the genitals (penis or scrotum). Do not let others apply this medication to your body.
The dosage is based on your medical condition, lab tests, and response to treatment.

Do not increase your dose or use this drug more often or for longer than prescribed. When testosterone is misused or abused, you may have withdrawal symptoms (such as depression, irritability, tiredness) when you suddenly stop using the drug. These symptoms may last from weeks to months.
