What is Delestrogen?

Delestrogen is used to treat certain symptoms of menopause such as hot flashes and vaginal dryness, burning, or itching. It is also used to treat a lack of estrogen that is caused by ovarian failure or a condition called hypogonadism.

Some forms of estradiol injection are used in men to treat the symptoms of prostate cancer. Delestrogen treats only the symptoms of prostate cancer but does not treat the cancer itself.

Delestrogen may also be used for purposes not listed in this medication guide.

How is Delestrogen given?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Delestrogen is injected into a muscle, usually given once every 1 to 4 weeks, depending on the condition being treated. A healthcare provider may teach you how to properly use the medication by yourself.

Prepare an injection only when you are ready to give it. Call your pharmacist if the medicine looks cloudy, has changed colors or has particles in it.

Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.

Delestrogen may increase your risk of developing a condition that can lead to uterine cancer. To lower this risk, your doctor may also want you to take a progestin. Report any unusual vaginal bleeding right away.

If you need surgery or will be on long-term bed rest, tell the surgeon ahead of time that you are using Delestrogen. You may need to stop using the medicine for a short time.

Your doctor will need to check your progress on a regular basis. Self-examine your breasts for lumps on a monthly basis, and have regular mammograms while using Delestrogen.

Store at room temperature away from moisture and heat.
