Norethindrone
Summary
Norethindrone is used to treat conditions like endometriosis, abnormal uterine bleeding and secondary amenorrhea.
Norethindrone is a synthetic progestin. It works by stopping the growth of the uterine lining and causing the uterus to produce certain hormones. This helps manage symptoms associated with these conditions.
Norethindrone is taken orally, usually once a day. For endometriosis, it's taken for 6 to 9 months. For inducing a normal menstrual cycle, it's taken for 5 to 10 days during the second half of the cycle.
Common side effects of Norethindrone include irregular vaginal bleeding, changes in menstrual flow, nausea, vomiting, and weight changes. Serious side effects, though uncommon, include vision changes, severe headaches, chest pain, and signs of blood clots.
Norethindrone is not recommended for use if you are pregnant, breastfeeding, or have a history of blood clots, stroke, heart attack, or liver disease. It's also contraindicated in cases of undiagnosed vaginal bleeding and known or suspected breast cancer. Smoking may increase the risk of serious side effects.
Indications and Purpose
How does Norethindrone work?
Norethindrone works by mimicking the hormone progesterone, which helps regulate the menstrual cycle and prevent ovulation. It thickens cervical mucus, making it harder for sperm to reach an egg, and alters the uterine lining to prevent a fertilized egg from implanting. This makes it effective for contraception and managing menstrual disorders. Think of it like setting up barriers to prevent pregnancy and regulate periods.
