What is Loestrin Fe 1/20

NorethisteroneThe Generic name of this drug
Treatment SummaryNorethisterone (also known as norethindrone) is a synthetic hormone that mimics the natural hormone progesterone. It is a second-generation progestin, which means it is more powerful than other progestins. It is used in birth control pills and in hormone replacement therapy to regulate menstruation and treat endometriosis. It was first developed in 1951 and was first marketed as an oral contraceptive in 1962.

Effectiveness

How Loestrin Fe 1/20 Affects PatientsNorethisterone is a medication taken orally for contraception or to treat other hormone-related conditions. It is much stronger than the natural progesterone our bodies produce and works by altering the cervical and endometrial function, as well as blocking certain hormones released by the pituitary gland. Taking this medication may slightly increase the risk of developing breast cancer, so patients should be aware and practice regular self-exams.
How Loestrin Fe 1/20 works in the bodyNorethisterone works in a few different ways to prevent pregnancy. It thickens cervical mucus to stop sperm from entering the uterus. It also changes the endometrium, making it difficult for a fertilized egg to implant. Norethisterone also suppresses hormones that help with ovulation, so eggs cannot be released. For menopausal women, norethisterone is used to prevent endometrial cancer. It does this by blocking the growth of the endometrium. Norethisterone has low activity at other hormone receptors, like the androgen receptor and glucocorticoid receptor. This

Loestrin Fe 1/20 for Birth Control
I've been taking Lo Loestrin Fe for a decade now, and it has effectively prevented pregnancy the entire time. I didn't have any major side effects when I started, and still don't really experience them except for some occasional spotting. My doctors have reassured me that this is normal and won't impact my fertility down the line. Overall, I highly recommend this oral contraceptive!

Loestrin Fe 1/20 for Birth Control
I've been taking Lo Loestrin Fe for a decade now, and it has done wonders for me. No major side effects when I started, and it's kept me from getting pregnant all this time. My periods have basically stopped entirely (just some spotting a couple times a year), but my doctors assure me that this is normal and won't affect my fertility down the road. If you're considering an oral contraceptive, I would highly recommend this one!
