Testosterone Transdermal

Why is this medication prescribed?

Testosterone transdermal patches are used to treat the symptoms of low testosterone in men who do not produce enough natural testosterone. Testosterone is a hormone that is usually produced by the body that 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 supplying synthetic testosterone to replace testosterone that is normally produced naturally.

How should this medicine be used?

Transdermal testosterone comes as a patch to apply to the skin. It is usually applied once daily, and the schedule depends on the type of patch. Androderm patches are applied each night between 8 pm and midnight and left on for 24 hours. Testoderm patches are applied at the same time every morning (or any other regular time of day or night if the morning is inconvenient) and left on for 22****� hours. 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.

Androderm and Testoderm brand patches both contain testosterone, but they are manufactured differently and are intended for use on different parts of the body. Be sure you know which type of patch you are using and where, when, and how you are to apply your patches. Carefully read the manufacturer's patient information that comes with your patches.

If you are using Androderm patches, you should 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 a skin area with open sores or irritation. Also be sure that the patch will stay flat against the skin and will not be pulled 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 used.

If you are using Testoderm patches, you should apply them to your scrotum. Before you begin treatment, you should shave the hair from the area. Stretch your scrotal skin and shave with short gentle strokes of a disposable razor. Do not use soap, water, lotions, creams, or chemical hair removers. You should shave the area whenever hair has grown back, usually once or twice a week.

Androderm patches may be worn while swimming, bathing, or showering. However, Testoderm patches should be removed before water activities and placed on a clean, dry surface with the shiny side facing up. After water activities, dry your body and reapply the patch using the regular procedure.

If a patch becomes loose, smooth it down with your fingers. If it falls off, try to reapply the same patch. If the patch cannot be reapplied, apply a new one. However, if an Androderm patch falls off after twelve noon or if a Testoderm patch falls off after you have worn it for 12 hours, do not apply a new patch until your next scheduled application time.

Testosterone patches may control your condition but will not cure it. It may take up to 8 weeks before you feel the full benefit of testosterone. 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.

To use Androderm patches, follow these steps:

  • Clean and dry the spot where you will apply the patch.
  • Tear the foil pouch along the edge and remove the patch.
  • Peel the protective liner and silver disc off the patch and throw them away.
  • Place the patch on your skin with the sticky side down and press down firmly with your palm for 10 seconds. Be sure it is completely stuck to your skin, especially around the edges.
  • 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.
  • Apply a new patch immediately by following steps 1-4.

To use Testoderm patches, follow these steps:

  • Be sure that your scrotum and your hands are warm and dry.
  • Tear the pouch along the top edge and remove the patch.
  • Peel the clear plastic liner off the patch and throw it away.
  • Warm the patch by holding it a few inches away from a mild heat source such as a light bulb or blowdryer.
  • Sit or stand in a comfortable position. Stretch the skin of your scrotum to smooth out the folds.
  • Press the shiny side of the patch onto your scrotum. Cup your hand over the patch and hold it in place for 10 seconds.
  • Be sure that the edges of the patch are pressed firmly against your skin. If the patch falls off, repeat steps 4****� Be sure to warm the patch again and try holding it in place for longer than 10 seconds.
  • Put on close fitting underwear to hold the patch in place. If the patch still falls off, wearing an athletic supporter may help.
  • When you are ready to remove the patch, gently peel 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.

What special precautions should I follow?

Before using testosterone patches,

  • tell your doctor and pharmacist if you are allergic to testosterone, ethanol, or any other medications.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.

Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.

In case of emergency/overdose

If you wear too many patches, or wear patches for too long, too much testosterone may be absorbed into your bloodstream. In that case, you may experience symptoms of an overdose.
