NorethisteroneThe Generic name of this drug
Treatment SummaryNorethisterone, also known as norethindrone, is a synthetic hormone that works similarly to the hormone progesterone. It is a strong hormone used alone or in combination with other hormones for contraception and hormone replacement therapy. It was first created in 1951 and used to treat irregularities in menstruation and endometriosis before it was approved for use as an oral contraceptive in 1962.

Effectiveness

How Jencycla Affects PatientsNorethisterone is a medication used to prevent pregnancy or treat other hormone-related conditions. It is a synthetic form of progesterone, a hormone produced in the body. Norethisterone works by altering the function of the cervix and uterus, as well as blocking certain hormones responsible for the release of an egg. Taking norethisterone may slightly increase the risk of developing breast cancer, so patients should be aware of this and perform regular breast exams.
How Jencycla works in the bodyNorethisterone is a hormone that works to prevent pregnancy by thickening the cervical mucus and making the endometrium inhospitable for implantation. It does this by suppressing the release of follicle-stimulating hormone and luteinizing hormone from the anterior pituitary. When used as part of hormone replacement therapy in menopausal women, norethisterone works to protect against endometrial hyperplasia, which can increase the risk of cancer. It also has low affinity for other steroid receptors, such as the androgen receptor, which may be responsible for some negative side effects.

Jencycla for Birth Control
Jencycla is a fantastic form of birth control that I would recommend to anyone. It's been working great for me for the past five months with no negative side effects that I've noticed.

Jencycla for Birth Control
Though I don't always take it at the exact same time every day, this product has been very effective in preventing pregnancy. However, the side effects have been pretty tough to deal with. For example, I've been crying a lot more and gaining weight, which is really affecting my self-esteem. If you have a history of bad headaches, be prepared for them to get worse. All things considered though, I would still recommend this product.

Jencycla for Birth Control
I was really hesitant to try this pill because of all the negative things I'd heard, but everyone's body reacts differently so I decided to give it a shot. So far, the only side effects I've noticed are mood swings; which is an improvement from the migraines with aura that I used to experience.

Jencycla for Birth Control
I've been on this birth control for over five years now. I was put on it because I have migraines and can't use estrogen; however, my periods are irregular and heavier than before. Additionally, I never got pregnant while taking the pill on time but did get pregnant when I missed a dose. Consequently, I lost the baby at 13 weeks. My moods are up and down and I have a continuous lower abdominal pain just to name a few. Trying to talk my OB/GYN into changing it to something else.

I don't recommend this birth control pill. I constantly feel dizzy and have cramps that are really uncomfortable. Plus, the spotting is a daily occurrence which is annoying.

I got pregnant while taking this pill, twice in one month. I took the pill as directed both times and lost both pregnancies. I will never take this pill again.
