How should I use Estradiol Patch (estradiol transdermal)?

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Estradiol may increase your risk of developing a condition that may lead to uterine cancer. Your doctor may prescribe a progestin to help lower this risk. Report any unusual vaginal bleeding right away.

This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Apply the skin patch to clean, dry skin on your stomach or buttocks. Choose a different spot within these skin areas each time you apply a new patch. Avoid skin that is oily, irritated, or damaged.

Do not apply a skin patch to your breasts. Do not apply a patch where it might be rubbed off by tight clothing, such as under an elastic waistband.

If a patch falls off, try sticking it back into place. If it does not stick well, put on a new patch on a different skin area and leave it on only for the rest of your wearing time. Do not change your patch removal schedule.

Some transdermal patches contain aluminum that may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test.

If you need surgery or medical tests or if you will be on bed rest, you may need to stop using this medicine for a short time. Any doctor or surgeon who treats you should know that you are using estradiol.

Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment. Self-examine your breasts for lumps on a monthly basis, and have regular mammograms while using estradiol transdermal.

Store at room temperature away from moisture and heat. Keep each patch in its pouch until you are ready to use it.

After removing a skin patch, fold it in half so it sticks together. Discard the folded patch in a place children and pets cannot get to.

What should I avoid while using Estradiol Patch (estradiol transdermal)?

Grapefruit and grapefruit juice may interact with estradiol and lead to unwanted side effects. Discuss the use of grapefruit products with your doctor.
