Estradiol Transdermal Patch: MedlinePlus Drug Information

Transdermal estradiol comes as a patch to apply to the skin. Transdermal estradiol is usually applied once or twice a week, depending on the brand of patch that is used. Some women wear a patch all the time, and other women wear a patch according to a rotating schedule that alternates 3 weeks when the patch is worn followed by 1 week when the patch is not worn. Always apply your transdermal patch on the same day(s) of the week every week. There may be a calendar on the inner flap of your medication carton where you can keep track of your patch change schedule. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use transdermal estradiol exactly as directed. Do not apply more or fewer patches or apply the patches more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of transdermal estradiol and may increase your dose if your symptoms are still bothersome. If you are already taking or using an estrogen medication, your doctor will tell you how to switch from the estrogen medication you are taking or using to transdermal estradiol. Be sure you understand these instructions. Talk to your doctor about how well transdermal estradiol works for you.

You should apply estradiol patches to clean, dry, cool skin in the lower stomach area, below your waistline. Some brands of patches may also be applied to the upper buttocks. Ask your doctor or pharmacist or read the manufacturer's information that comes with your patches to find the best place(s) to apply the brand of patches you have received. Do not apply estradiol patches to the breasts or to skin that is oily, damaged, cut, or irritated. Do not apply estradiol patches to the waistline where they may be rubbed off by tight clothing or to the lower buttocks where they may be rubbed off by sitting. Be sure that the skin in the area where you plan to apply an estradiol patch is free of lotion, powders, or creams. After you apply a patch to a particular area, wait at least 1 week before applying another patch to that spot.

Talk to your doctor or pharmacist or read the manufacturer's information that came with your medication to find out if you need to be careful when you swim, bathe, shower, or use a sauna while wearing an estradiol transdermal patch. Some brands of patches are not likely to be affected by these activities, but some brands of patches may loosen.

If the patch loosens or falls off before it is time to replace it, try to press it back in place with your fingers. Be careful not to touch the sticky side of the patch with your fingers while you are doing this. If the patch cannot be pressed back on, fold it in half so it sticks to itself, dispose of it safely, so that it is out of the reach of children and pets, and apply a fresh patch to a different area. Replace the fresh patch on your next scheduled patch change day.

Each brand of estradiol transdermal patches should be applied following the specific directions given in the manufacturer's information for the patient. Read this information carefully before you start using estradiol transdermal and each time you refill your prescription. Ask your doctor or pharmacist if you have any questions. The following general directions can help you remember some important things to do when you apply any type of estradiol transdermal patch.

1. Tear open the pouch with your fingers. Do not use scissors because they may damage the patch. Do not open the pouch until you are ready to apply the patch.
2. Remove the patch from the pouch. There may be a silver foil sticker used to protect the patch from moisture inside the pouch. Do not remove this sticker from the pouch.
3. Remove the protective liner from the patch and press the sticky side of the patch against your skin in the area you have chosen to wear your patch. Some patches have a liner that is made to peel off in two pieces. If your patch has that type of liner, you should peel off one part of the liner and press that side of the patch against your skin. Then fold back the patch, peel off the other part of the liner and press the second side of the patch against your skin. Always be careful not to touch the sticky side of the patch with your fingers.
4. Press down on the patch with your fingers or palm for 10 seconds. Be sure that the patch is firmly attached to your skin, especially around its edges.
5. Wear the patch all the time until it is time to remove it. When it is time to remove the patch, slowly peel it off of your skin. Fold the patch in half so that the sticky sides are pressed together and dispose of it safely, so that is out of reach of children and pets.
6. If a sticky substance remains on your skin after you remove the patch, you should wait 15 minutes and then remove the substance using an oil or lotion.
