Norethisterone is a synthetic form of progesterone commonly used to postpone menstruation, typically found in contraceptive pills. Additionally, it can be used in hormone therapy for menopause and the treatment of women's reproductive diseases. The indications for using norethisterone (5 mg) are as follows:
- Consume three days before the expected menstrual period.
- Take three times a day, one tablet each time.
- Menstruation can be postponed for 14 to 17 days.
Purposes of Usage
Some considerations leading women to take norethisterone include experiencing painful, heavy, uncomfortable, or irregular periods, as well as medical conditions such as endometriosis and premenstrual syndrome (PMS). On the other hand, this pill can also be consumed during vacations or sports competitions to prevent menstruation during those times.
Avoid consumption if experiencing the following:
- Currently pregnant or suspected of being pregnant.
- Currently breastfeeding.
- Experiencing severe vaginal bleeding.
- History of breast or genital cancer.
- History of liver cancer or liver problems.
- History of gestational pemphigoid.
- Recently had angina, a heart attack, or a stroke due to blood clotting.
- Experiencing blood clots in the legs or lungs.
- Norethisterone is usually consumed during vacations or sports competitions.

How it Works
Norethisterone works by simulating the effects of progesterone in the body. When progesterone levels increase, the uterine lining prepares to receive a fertilized egg. However, when pregnancy does not occur, progesterone decreases, and the uterine lining sheds, resulting in menstruation.
Norethisterone works to maintain high progesterone levels (preventing a decrease) or deceive the body into thinking someone is pregnant. This delays the release of the uterine lining. Consequently, a woman does not experience menstruation as per their normal cycle.
Side Effects
Some side effects that may be experienced after taking norethisterone include nausea, breast pain, fatigue, bloating, headaches, and reduced sexual desire. Therefore, it is advisable to consult with a doctor or pharmacist for more comprehensive information on usage recommendations.
If experiencing severe headaches, stabbing pain in one leg, pain while breathing, coughing up blood, sudden numbness on one side of the body, changes in vision or hearing, or yellowing of the skin or whites of the eyes, discontinue norethisterone consumption and seek medical attention immediately.
After Stopping Norethisterone Consumption
After discontinuing norethisterone, menstruation usually occurs within 2 to 3 days, and the menstrual cycle resumes as usual after that time. However, if menstruation does not occur, consult with a doctor at the nearest healthcare facility. It is essential to note that norethisterone (5 mg) is intended solely for menstrual postponement, not as a contraceptive.
Menstruation usually occurs a few days after stopping norethisterone consumption.
So, norethisterone is a synthetic form of progesterone. It deceives the body into thinking someone is pregnant, preventing the shedding of the uterine lining and postponing menstruation. The consumption of this pill is intended only for menstrual delay and is not a contraceptive method. Is it clear now? If you have any questions, feel free to ask in the comments section, Ladies!
