What is the most important information I should know about testosterone implants?

What is testosterone?

Testosterone is a naturally occurring sex hormone produced in a man's testicles.

Testosterone implants are used in men and boys to treat conditions caused by a lack of testosterone.

Testosterone implants are not for use in treating low testosterone due to getting older. Testosterone implants have not been shown to be safe and effective for enhancing athletic performance.

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

What should I discuss with my healthcare provider before receiving testosterone implants?

• prostate cancer; or
• male breast cancer.

Being treated with testosterone implants may increase your risk of enlarged prostate or prostatic cancer. Ask your doctor about your individual risk.

Tell your doctor if you have ever had:

• heart problems;
• liver disease; or
• kidney disease.

How are testosterone implants given?

Testosterone implants are inserted under the skin on the back side of your hip area, usually once every 3 to 6 months. The implants slowly release testosterone and are absorbed in your body over time.

You will receive testosterone implants with a minor surgical procedure in a clinic or doctor's office.

Follow your doctor's instructions about caring for your surgical incision after receiving testosterone implants.

You may need frequent medical tests. Even if you have no symptoms, tests can help your doctor determine if this medicine is effective.

Testosterone can affect bone growth. Young boys treated with testosterone implants may need x-rays every 6 months to check bone development.

If treatment needs to be stopped, the implants may need to be surgically removed early. Do not try to remove the implants yourself. Your doctor will determine whether you need continued treatment with testosterone implants.

Testosterone implants can affect the results of certain medical tests. Tell any doctor who treats you that you are using this medicine.

What happens if I miss a dose?

What happens if I overdose?

Since the testosterone implant contains a specific amount of the medicine, you are not likely to receive an overdose.

What should I avoid while using testosterone implants?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
