Effectiveness

How Larin 1/20 Affects PatientsNorethisterone is a medicine taken by mouth to prevent pregnancy or treat other hormone-related issues such as menopause and endometriosis. It works similarly to the hormone progesterone, but is more powerful. It can affect cervical and uterine function and can stop eggs from maturing and being released from the ovaries. Taking norethisterone in combination with other contraceptives may slightly increase the risk of breast cancer, so those taking it should be aware of this risk and do regular self-exams to check for any lumps.
How Larin 1/20 works in the bodyNorethisterone works by affecting different parts of the body. In the reproductive tract, it thickens mucus to stop sperm from moving. It also changes the lining of the uterus, making it harder for a fertilized egg to attach and grow. In the brain, it reduces the release of hormones that stimulate eggs to develop and be released from the ovaries. In menopausal women, it helps prevent overgrowth of the endometrium, which can increase the risk of cancer. Finally, it has minimal interaction with other steroid receptors, but may cause side effects like acne and changes to cholesterol levels.

Larin 1/20 for Birth Control
I was switched to this generic Loestrin after the price of my other one went up. They say that all generics are created equal but I have never believed that. Ever since starting this drug my breasts and nipples have been so sore and I'm now experiencing cramps during my period again. Never had any of that before starting this.
3.7Patient Review

Larin 1/20 for Endometriosis
While this medication comes with some serious side effects like crying jags and breast soreness, it has effectively helped to manage my flare-ups. I'm not thrilled about the downsides, but they're worth putting up with for now.
