What can I expect during treatment?
While you’re on Lupron Depot, your body will be going through some changes.
In the first week or two, your estrogen level will increase. During that time, you may notice a temporary increase in symptoms. In the following weeks you should start to feel relief from endometriosis pain, and in the following months your periods should stop.
Since menstruation usually stops with effective doses of Lupron Depot, you should notify your doctor if regular menstruation persists. If you miss successive doses of Lupron Depot, you may experience breakthrough bleeding.
Lupron Depot is not a method of birth control. Even though you may not have periods, unprotected intercourse could result in pregnancy. You should use non-hormonal birth control such as condoms, a diaphragm with contraceptive jelly or an IUD to prevent pregnancy. If you think you have become pregnant while on Lupron Depot, talk to your doctor immediately.

LUPRON DEPOT® (leuprolide acetate for depot suspension) 3.75 mg and – 3 Month 11.25 mg is used for the management of endometriosis, including pain relief and reduction of endometriotic lesions. LUPRON DEPOT with daily norethindrone acetate 5 mg is also indicated for initial management of endometriosis and for management of recurrence of symptoms. The recommended initial treatment is no more than 6 months. Repeat treatment for endometriosis should be limited to 6 months.
You should not receive LUPRON DEPOT if you are or may become pregnant, are breast-feeding or have undiagnosed vaginal bleeding. Increased endometriosis symptoms (i.e. pelvic pain or pressure and/or pain during intercourse) may occur for 1 or 2 weeks after starting this drug. Development or worsening of depression has occurred. Condoms, a diaphragm with contraceptive jelly, or an IUD is required to prevent pregnancy. Thinning of the bones, which may not be completely reversible, can occur during treatment with this drug. Norethindrone acetate used as add-back therapy with LUPRON DEPOT has additional serious risks and considerations.

Lupron Depot suppresses sex hormone production, leading to a low-estrogen state. While on therapy, most women experience side effects similar to those associated with menopause, such as hot flashes, which are temporary and reversible after completing therapy. You should know that Lupron Depot does NOT put you into menopause. You may also experience bone density loss, which may not be completely reversible. These side effects are expected and signal a decrease in estrogen levels. This can lead to a reduction in lesions and pain associated with endometriosis.
Your doctor can prescribe Add-back* from Day 1 of your Lupron Depot treatment. This can help you to experience fewer hot flashes and reduce bone density loss.
You should NOT take Add-back* therapy with Lupron Depot if you currently have or have previously had any clotting disorder, heart disease, stroke, liver disease or breast cancer. Also, you should tell your health care provider before beginning treatment with norethindrone acetate if you currently have or have previously had high cholesterol, migraines, epilepsy, depression or smoke.
The hormonal effects of Lupron Depot are reversible.
After completion of a full course of treatment with Lupron Depot therapy, the hormonal effects you may have experienced will subside:
- Your normal menstrual cycle will return. In one study, 95% of women resumed their normal cycle within 3 months after completion of therapy
- Low-estrogen symptoms, such as hot flashes, usually disappear within 2.5 to 5.5 months from the day of the last injection, depending on your dose of medication
- Bone density loss trends toward recovery after discontinuing therapy. Since some conditions may increase the possibility of bone thinning, you should tell your doctor if you smoke, use alcohol in excess, have a family history of osteoporosis (thinning of the bones with fractures), or are taking other medications that cause thinning of the bones
