What Is Norethisterone?
Norethisterone is a synthetic version of the hormone progesterone used for various gynaecological purposes. It helps regulate menstrual cycles and manage certain health conditions. In Singapore, it can only be obtained with a doctor's prescription. It is commonly used as a short-term solution to delay menstruation, especially for important events or activities where having a period might be inconvenient.
Norethisterone: How Does It Work?
Norethisterone works by simulating the effects of progesterone, which is essential for regulating the menstrual cycle. By increasing progesterone levels synthetically, it helps prevent the shedding of the uterine lining and supports the management of various menstrual-related conditions.

Norethisterone Uses
Delay Menstruation
Norethisterone is commonly used to delay periods for specific purposes, such as travel, weddings, sports events, or other activities. By temporarily halting the menstrual process, it helps individuals avoid the discomfort, inconvenience, and potential limitations associated with menstruation, providing flexibility during these occasions.
Heavy Menstrual Bleeding
Norethisterone is prescribed to manage menorrhagia, or heavy menstrual bleeding. It helps control excessive blood loss and prevent prolonged or irregular periods. By reducing the severity of menstrual flow, norethisterone can alleviate symptoms such as fatigue, pain, and disruptions to daily life, improving overall comfort and quality of life for those affected.
Endometriosis Management
Norethisterone can also help manage symptoms of endometriosis, a condition where tissue similar to the uterine lining grows outside of it, causing pain and heavy periods. By regulating hormonal activity, norethisterone can reduce tissue growth and ease symptoms, leading to less pain, lighter periods, and improved daily comfort.

Norethisterone Dosage to Delay Period
To delay menstruation, norethisterone is typically prescribed to be taken 3 to 4 days before the expected period and continued for up to two weeks. Menstruation usually resumes within two to three days after stopping the medication. The exact schedule may vary based on individual health needs, so consulting a doctor for proper guidance is essential.
Side Effects of Norethisterone to Delay Period
Although norethisterone is usually well-tolerated, it may cause some side effects, such as:
- Abdominal discomfort
- Nausea
- Headaches
- Dizziness
- Breast tenderness
More severe side effects, though rare, may include swelling, rashes, itching
over the body, and difficulty breathing. If you experience such symptoms,
you should seek medical attention promptly.
