Why is this medication prescribed?
Testosterone transdermal patches are used to treat the symptoms of low testosterone in adult men who have hypogonadism (a condition in which the body does not produce enough natural testosterone). Testosterone is used only for men with low testosterone levels caused by certain medical conditions, including disorders of the testicles, pituitary gland, (a small gland in the brain), or hypothalamus (a part of the brain) that cause hypogonadism. Your doctor will order certain lab tests to check your testosterone levels to see if they are low before you begin to use testosterone transdermal patches. Testosterone should not be used treat the symptoms of low testosterone in men who have low testosterone due to aging ('age-related hypogonadism'). Testosterone is in a class of medications called androgenic hormones. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. Testosterone transdermal patches work by replacing the testosterone that is normally produced by the body.
How should this medicine be used?
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 patch(es) 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 the patch(es) 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.
Use testosterone patches immediately after opening. Do not use if the pouch seal is broken or if the patch appears to be damaged. Do not cut the patches.
After you apply the patch(es), do not shower, bathe, swim, or wash the place where you applied the medication for at least 3 hours. 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.
Exercise or excessive sweating may loosen a patch or cause it to fall off. 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. Do not tape the testosterone patch to the skin.
Your doctor may adjust your dose of testosterone depending on the amount of testosterone in your blood during your treatment.
Testosterone patches may control your condition but will not cure it. 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.
