What Are Norethisterone Tablets?

Norethisterone Tablets help manage various menstrual-related conditions by working like the body’s natural hormone, progesterone. Doctors prescribe them to treat heavy, painful, or irregular periods, as well as premenstrual tension (PMT) and endometriosis. In some cases, they can delay periods when needed. At higher doses, Norethisterone may also help slow the growth of certain breast cancer cells. Always follow a doctor’s advice before starting this medication.

What Are Norethisterone Tablets Used For?

Doctors prescribe Norethisterone to manage a range of hormone-related conditions, including:

Heavy, painful, or irregular periods – Helps regulate the menstrual cycle and reduce discomfort.
Premenstrual tension (PMT) – Eases symptoms such as mood swings, bloating, and headaches.
Endometriosis – Helps control the growth of womb tissue outside the womb, reducing pain and inflammation.
Breast cancer – Can be used at higher doses to slow the growth of certain cancer cells.
Period delay – May be taken to postpone a period for a short time. Speak to a doctor before using it for this purpose.

How Do Norethisterone Tablets Work?

Norethisterone Tablets work like progesterone to regulate the menstrual cycle, reduce heavy bleeding, and stabilise the womb lining. This helps manage hormone-related conditions such as endometriosis and premenstrual tension.

How Should Norethisterone Be Taken?

The dosage depends on the condition being treated, so always follow your doctor’s instructions. Below are the usual guidelines:

— Period delay – One tablet three times a day, starting three days before the period is due. The period should start a few days after stopping the tablets.
