Testosterone transdermal patches are used to treat the symptoms of low testosterone in men whose bodies do not produce enough natural testosterone. Testosterone, a hormone that is usually produced by the body, contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. Symptoms of low testosterone include decreased sexual desire and ability, extreme tiredness, low energy, depression, and loss of certain male characteristics such as muscular build and deep voice. Testosterone patches work by providing a steady supply of testosterone through the skin to the body.
Transdermal testosterone comes as a patch to apply to the skin. It is usually applied each night between 8:00 p.m. and midnight and left in place for 24 hours. Apply testosterone patches at around the same time every evening.Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use testosterone patches exactly as directed. Do not apply more or fewer patches or apply the patches more often than prescribed by your doctor.
Choose a spot on your back, stomach, thighs, or upper arms to apply your patch(es). Be sure that the spot you have chosen is not oily, hairy, likely to perspire heavily, over a bone such as a shoulder or hip, or likely to be under pressure from sitting or sleeping. Do not apply to the scrotum or to a skin area with open sores, wounds, or irritation. Also be sure that the patch will stay flat against the skin and will not be pulled, folded, or stretched during normal activity. Choose a different spot each night and wait at least 7 days before applying another patch to a spot you have already used.
Wear your testosterone patch(es) at all times until you are ready to apply the new patch(es). Do not remove your patch(es) before swimming, bathing, showering, or sexual activity.
If a patch becomes loose, smooth it down with your fingers. If a patch falls off before noon, apply a new patch. If a patch falls off after noon, do not apply a new patch until your next scheduled application time that evening.
Testosterone patches may control your condition but will not cure it. I Continue to use testosterone patches even if you feel well. Do not stop using testosterone patches without talking to your doctor. If you stop using testosterone, your symptoms may return.
Clean and dry the spot where you will apply the patch.

When you are ready to remove the patch, pull it off the skin and throw it away in a trash can that is out of the reach of children and pets. Children and pets can be harmed if they chew on or play with used patches.
