What is Femhrt
NorethisteroneThe Generic name of this drug
Treatment SummaryNorethisterone (also known as norethindrone) is a synthetic hormone belonging to a group of drugs called progestins. It is used to imitate the effects of the hormone progesterone, and is commonly prescribed for contraception, hormone replacement therapy, and to treat irregular periods and endometriosis. It was first developed in 1951 in Mexico City and was later approved for use in oral contraceptives in 1962.

Effectiveness
How Femhrt Affects PatientsNorethisterone is a type of medication taken orally that can be used as a form of birth control or to treat other hormone-related issues such as menopausal symptoms or endometriosis. It works similarly to natural progesterone, but with a much greater effect. It affects the cervix and endometrium, and can also influence pituitary hormones that are part of the ovulation process. Taking norethisterone does slightly increase the risk of developing breast cancer, so it is important to be aware of this before taking the medication and to perform regular breast self-exams to check for any developing masses
How Femhrt works in the bodyNorethisterone works by blocking sperm from entering the uterus, making it harder for a fertilized egg to implant. It also suppresses hormones from the pituitary gland that help eggs develop and be released. When used as part of hormone replacement therapy, norethisterone helps protect against endometrial cancer by preventing the growth of the endometrium. Although it has a low affinity for other steroid receptors, it is believed to have a slight effect on androgen receptors, which can cause side effects like acne and changes in blood lipids.

Femhrt Reviews: What are patients saying about Femhrt?
5Patient Review
10/10/2013 I've been on this medication for two months to help with hot flashes and night sweats. After the first week, I already felt so much better! I did have some vaginal bleeding for a couple of weeks, but when I told my doctor about it, they said it was a normal side effect. This treatment has made me feel like a normal woman again!

11/11/2011 This treatment really helped me deal with my menopause symptoms. It was very effective in reducing hot flashes, night sweats, and mood swings. I highly recommend it to other women dealing with menopause.
5Patient Review
6/17/2013 So far, I really like this treatment. I have noticed a change in my vision, but my doctor says that it's just a normal part of aging. Thank god the hot flashes have gone away though!

10/21/2012 I've found that my hot flashes have decreased significantly since taking this medication.
5Patient Review
8/20/2019 Femhrt worked great for me when I started having hot flashes and night sweats. My doctor did warn me that long-term use could lead to cancer, so after six months I stopped. But in the meantime it was a total lifesaver.
5Patient Review
9/10/2010 This treatment effectively mitigated most of my hot flashes. I still have the occasional night sweat, but it's a small price to pay.

9/20/20094.7Patient Review
11/29/2014 Femhrt has been working great for me. I was experiencing 20 or more hot flashes every day, and now I'm down to just one to three per day. They're also not as severe as they were before I started taking the medication. It did take a little while to start working, but I'm feeling normal again.
4.3Patient Review
5/31/2013 This medication was extremely effective for me; it completely stopped my menopause symptoms. However, now I'm experiencing some bleeding and will have to go back to the doctor. I hope she doesn't take me off the medication, as it's the only thing that has worked so far.
4Patient Review
9/21/2010 I started taking Femhrt 2 years ago at age 48. My hot flashes stopped within days. However, I have started having hot flashes again. Femhrt seems to have lost it's effectiveness on me! Next visit to my gyn, I will discuss other options.

4/26/2011 This treatment really alleviated my hot flashes and gave me back my energy. I'm very pleased with it!
