Pain Medication and Hormonal Treatment for Endometriosis

Pain Medication. For some women with mild symptoms, doctors may suggest taking over-the-counter medicines for pain. These include: ibuprofen (Advil and Motrin) or naproxen (Aleve).

Hormone Treatment. When pain medicine is not enough, doctors often recommend hormone medicines to treat endometriosis. Only women who do not wish to become pregnant can use these drugs. Hormone treatment is best for women with small growths who don't have bad pain.

Hormones come in many forms including pills, shots, and nasal sprays. Many hormones are used for endometriosis including:

* Birth control pills block the effects of natural hormones on endometrial growths. So, they prevent the monthly build-up and breakdown of growths. This can make endometriosis less painful. Birth control pills also can make a woman's periods lighter and less uncomfortable. Most birth control pills contain two hormones, estrogen and progestin. This type of birth control pill is called a "combination pill." Once a woman stops taking them, the ability to get pregnant returns, but so may the symptoms of endometriosis.

* Progestins or progesterone medicines work much like birth control pills and can be taken by women who can't take estrogen. When a woman stops taking progestins, she can get pregnant again. But, the symptoms of endometriosis return too.

* Gonadotropin releasing hormone agonists or GnRH agonists slow the growth of endometriosis and relieve symptoms. They work by greatly reducing the amount of estrogen in a woman's body, which stops the monthly cycle. Leuprolide (Lupron®) is a GnRH agonist often used to treat endometriosis. GnRH agonists should not be used alone for more than six months. This is because they can lead to osteoporosis. But if a woman takes estrogen along with GnRH agonists, she can use them for a longer time. When a woman stops taking this medicine, monthly periods and the ability to get pregnant return. But, usually the problems of endometriosis also return.

* Danazol is a weak male hormone. Nowadays, doctors rarely recommend this hormone for endometriosis. Danazol lowers the levels of estrogen and progesterone in a woman's body. This stops a woman's period or makes it come less often. Danazol also gives pain relief. But it often causes side effects like oily skin, weight gain, tiredness, smaller breasts, and hot flashes. Danazol does not prevent pregnancy and can harm a baby growing in the uterus. Since it can't be used with other hormones, like birth control pills, doctors recommend using condoms, diaphragms, or other "barrier" methods to prevent pregnancy.
