Endometriosis - Medications
Medicines can be used to reduce pain and bleeding and, in some cases, to shrink endometriosis growths. For women who are not trying to get pregnant, birth control hormones and
anti-inflammatories (NSAIDs) are usually recommended first. They are least
likely to cause serious side effects and can be a long-term treatment
option.1 But if infertility from endometriosis is your main problem, medicines are generally not

Birth control hormones (patch, pills, or ring) stop monthly
ovulation and the growth, shedding, and bleeding that
makes endometriosis painful. Birth control hormones improve endometriosis pain
for most women.4 And they are the
hormone therapy that is least likely to cause bad side effects. For this
reason, many women can use them for years. Other hormone therapies can only be
used for several months to 2 years. For more general information on birth
control hormones, see
Birth Control Pills, Patch, or Ring.
Gonadotropin-releasing hormone agonist (GnRH-a)
therapy lowers estrogen, triggering a state that is like menopause. This shrinks implants and
reduces pain for most women.
- Progestin (pills or Depo-Provera shot) stops
ovulation and lowers estrogen. For most women, it shrinks endometriosis growths and reduces
pain. Some studies show that the levonorgestrel intrauterine device (IUD) decreases pain.5
Danazol therapy lowers estrogen levels
androgen levels, triggering a menopause-like state.
This shrinks growths and reduces pain for most women. This
relief usually lasts for 6 to 12 months after treatment. But danazol side
effects can be significant.
All hormone therapies for endometriosis can
cause side effects and pose certain health risks. Some cause especially
unpleasant side effects. Before starting a medicine or hormone therapy, review
its possible side effects. If they sound less difficult than your endometriosis
symptoms, discuss the therapy with your doctor.
