This medication can raise your blood pressure, which can increase your risk of having a heart attack or stroke. Your risk may be higher if you have a medical history of high blood pressure, heart disease, or stroke. Check your blood pressure regularly and tell your doctor if the results are high.

Your doctor will monitor your blood pressure regularly during treatment with this medication. Medications may be started or adjusted to control your blood pressure.

This medication is used by men who do not make enough of a natural substance called testosterone (hypogonadism). Testosterone belongs to a class of drugs known as androgens. 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 Instructions for Use provided by your pharmacist before you start using testosterone and each time you get a refill. Ask your health care professional how to prepare and use this medication. If you have any questions, ask your doctor or pharmacist.

Inject this medication under the skin as directed by your doctor, usually once every week. The injection is given in the abdomen. The dosage is based on your medical condition, testosterone blood levels, and response to treatment.

Before using, check this product for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the skin you are going to inject into (the injection site) with rubbing alcohol. Change the injection site each time to lessen injury under the skin. To lessen bruising, do not rub the injection site after a shot. Learn how to store and discard medical supplies safely.

Use this medication regularly to get the most benefit from it. To help you remember, use it on the same day each week. Mark your calendar with a reminder.

Misuse or abuse of testosterone can cause serious side effects such as heart disease (including heart attack), stroke, liver disease, mental/mood problems, abnormal drug-seeking behavior, or improper bone growth (in adolescents). 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.

Tell your doctor if your condition does not get better or if it gets worse.
