Before Using This Medicine:

Children—

However, elderly patients may be at an increased risk for developing prostate problems, including prostate cancer, which may require caution in patients receiving testosterone.

Proper Use of This Medicine:

This medicine comes with a Medication Guide and patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

Make sure that you wash your hands with soap and water before and after applying the patch.

For patients using the patch:

• After opening the pouch that contains the patch, apply the patch immediately.
• Apply the patch to a clean, dry area of the skin on your back, abdomen, thighs, or upper arm. Do not put the patch over burns, cuts, or irritated skin. Avoid putting the patch on oily or sweaty skin, or on areas covered with hair, since the patch may not stick tightly to these areas.
• Do not apply the patch to your scrotum or genital area. Avoid applying this medicine to a bony area (such as your shoulder) or to an area that might be under pressure for a long time (such as the back of your leg when you are sitting).
• The patch can be worn during sexual intercourse, or while taking a shower or bath. However, heavy exercise and sweating may cause the patch to fall off.
• When replacing an old patch, make sure that you apply the new patch on a different spot. Do not put another patch back on the same spot for at least 7 days.
• Do not apply any type of ointment product on your skin before you put on the patch.
• If a patch comes off, just put it back on the same spot. If the patch will not stick and you have been wearing it for fewer than 12 hours, put on a new patch. Then stay on your regular schedule and replace it with a fresh patch at your next regular time. If you have already been wearing the patch for more than 12 hours, do not put on a new patch. Wait to put on a new patch at your next regular time. Do not use extra patches to make up for the one that came off.
