leuprolide and norethindrone
Generic Name: leuprolide and norethindrone (LOO proe lide and NOR eth IN drone)
Brand Name: Lupaneta Pack
What is leuprolide and norethindrone?
Leuprolide and norethindrone is a combination medicine used to treat symptoms of endometriosis (overgrowth of uterine lining outside of the uterus).
Leuprolide overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily. Leuprolide reduces the amount of estrogen produced by the pituitary gland. Without enough estrogen, growth of endometrial tissue in the uterus slows down.
Norethindrone is a form of progesterone, a female hormone. Norethindrone helps leuprolide in the treatment of endometriosis by causing changes in your cervical mucus and uterine lining.
Leuprolide and norethindrone is not for use in women who are older than 65.
Leuprolide and norethindrone may also be used for purposes not listed in this medication guide.

FDA pregnancy category X. Leuprolide can harm an unborn baby or cause birth defects. Do not use if you are pregnant. Stop taking the norethindrone tablets and tell your doctor right away if you become pregnant during treatment.
Leuprolide is likely to cause you not to ovulate or have menstrual periods during the 6-month treatment period. However, you may still be able to get pregnant.
Use an intrauterine device (IUD) or a barrier form of birth control (condom or diaphragm with spermicide). Hormonal contraception (birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent pregnancy during your treatment.

Do not give norethindrone to anyone under 18 years old without medical advice.
How should I take leuprolide and norethindrone?
This medication is a combined treatment that includes a leuprolide injection and norethindrone tablets taken by mouth.
Leuprolide is usually given as a single injection into a muscle every 3 months for up to 6 months. Norethindrone tablets are taken every day for 3 months after your leuprolide injection.
A healthcare provider will give you the leuprolide injection. You will take the norethindrone tablets at home.
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Store norethindrone tablets at room temperature away from moisture and heat.
You may need frequent medical tests to help your doctor determine how long to treat you with leuprolide and norethindrone.
Leuprolide can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using leuprolide and norethindrone.
Call your doctor at once if your endometriosis symptoms get worse when you start using this medication.
Based on your response to leuprolide and norethindrone treatment, your doctor may want you to have a second 6-month treatment.
