What is Norethisterone?
Nostra tablets contain the active ingredient Norethisterone, which is a synthetic version of the naturally occurring female sex hormone, progesterone. In the body, Norethisterone mimics the effects of progesterone, helping to regulate the menstrual cycle and manage hormonal imbalances that can cause various gynecological issues. By regulating the growth and shedding of the uterine lining (endometrium), it provides therapeutic benefits for conditions where hormonal fluctuations are the root cause of symptoms.
Primary Uses of Nostra Tablets
Menstrual Cycle Regulation
Nostra tablets are primarily used to treat and regulate irregular menstrual cycles. This can include women who experience amenorrhea (the absence of periods) or have cycles that are consistently unpredictable. By introducing a regulated dose of a progestin, the medication helps to establish a more predictable cycle, often inducing a withdrawal bleed a few days after the tablets are stopped.
Heavy Menstrual Bleeding (Menorrhagia)
For women suffering from heavy periods, Nostra tablets can be highly effective. The synthetic progestin helps slow the growth of the uterine lining, which reduces the amount of bleeding during menstruation. Bleeding usually subsides within 48 hours of starting treatment.
Painful Menstruation (Dysmenorrhea)
In some cases, Nostra is prescribed to reduce uterine contractions and the production of prostaglandins, which are key contributors to the pain and cramps experienced during menstruation. This offers relief for women whose daily lives are severely impacted by painful periods.
Endometriosis Management
Endometriosis is a condition where uterine-like tissue grows outside the uterus, causing significant pain and other symptoms. Nostra tablets work by preventing this tissue from growing too quickly, which helps to alleviate the associated symptoms. For endometriosis, treatment may continue for several months to be effective.
Delaying Periods
Some women may need to delay their menstrual cycle for special occasions, such as holidays or religious events. By starting Nostra tablets a few days before the expected period, it can effectively postpone menstruation until the tablets are stopped. The period typically resumes two to four days after the medication is discontinued.
Other Specialized Uses
- Support in Hormone Replacement Therapy (HRT): For postmenopausal women using estrogen therapy, Nostra tablets can be added to prevent endometrial hyperplasia (the thickening of the uterine lining).
- Breast Cancer Treatment: In some specialized cases, higher doses of Norethisterone are used in the treatment of breast cancer.
Side Effects and Considerations
Like all medications, Nostra tablets can cause side effects. Common side effects include headaches, nausea, abdominal pain, and breast tenderness. Irregular vaginal bleeding or spotting between periods is also a frequent occurrence, especially when first starting the medication. Serious, though rare, side effects include blood clots, severe headaches, and vision problems, which require immediate medical attention.
Several precautions are necessary when taking Norethisterone. It is contraindicated for pregnant or breastfeeding women. Patients with a history of blood clots, liver disease, or certain hormone-sensitive cancers should not take this medication. Smoking significantly increases the risk of serious side effects, such as blood clots.

By acting as a synthetic progestin, it helps regulate the menstrual cycle, manage painful or heavy bleeding, and treat conditions like endometriosis and PMS.
