Norimin is a type of combined hormonal contraceptive (CHC) known as ‘the pill’, or the combined oral contraceptive pill (COCP). It contains two active ingredients which are synthetic (man-made) forms of naturally occurring female sex hormones. These are ethinyl estradiol (a synthetic form of oestrogen) and norethisterone (a synthetic form of progesterone). CHCs such as Norimin prevent the release of an egg from the ovary (ovulation). They change the mucus in the cervix (entrance to the womb) and the lining in the womb which helps make it difficult for sperm to reach an egg, or for an egg to embed itself in the womb lining.

What is Norimin?

Norimin is a contraceptive pill that is known as a combined oral contraceptive as it contains both estrogen and progestogen hormones. Such contraceptives prevent pregnancy by preventing the release of egg from the ovary during menstrual cycles. The contraceptive action is also aided by changes to the mucus found in the cervix. This contraceptive pill also used in the treatment of irregular, painful and heavy periods.

How does Norimin work?

Norimin is made of two active ingredients ethinylestradiol and norethisterone. These are synthetic hormones that are like the natural female sex hormones oestrogen and progesterone.

In a normal menstrual cycle, the levels of sex hormones fluctuate through each month to aid the process of ovulation. Due to these hormones, an egg Is released from the ovaries (ovulation) and the womb is prepared for pregnancy. If the egg remains unfertilized at the end of the cycle, the hormone levels fall, and lining of the womb is shed which causes menstruation. Combined oral contraceptives like Norimin override this normal menstrual cycle.

The synthetic hormones in the pill make your body think that ovulation has already occurred. This prevents the process of ovulation from occurring. Another way these hormones prevent pregnancy is by increasing the thickness of mucus in the cervix. This prevents the sperm from entering the womb and fertilizing an egg. Norimin can also change the quality of the endometrium to prevent fertilized eggs from implanting to it.

What are the benefits of taking Norimin?

  • Prevents pregnancy if used correctly.

Frequently Asked Questions

Yes, Norimin is often prescribed to treat heavy periods, painful cramps, or irregular menstrual cycles. The hormones in Norimin help regulate the menstrual cycle, making periods lighter and less painful.

Some users may experience reduced premenstrual symptoms (PMS) while taking it. Norimin may also be recommended for conditions like dysmenorrhoea or menorrhagia under the supervision of a healthcare professional.

Norimin does not cause long-term infertility—your natural fertility should return once you stop taking the pill. Some women may experience a brief delay in ovulation after discontinuing, but this is usually temporary.

You may notice irregular cycles for a few months as your body readjusts. If you are trying to conceive after stopping Norimin, you can track ovulation using fertility apps or ovulation tests.

You can stop taking Norimin at any time, but it is best to do so at the end of a pack to avoid irregular bleeding. Your fertility will return shortly after stopping the pill. You can use another method of contraception if you are not planning to become pregnant.

Your natural menstrual cycle may take a few weeks or months to regulate again. If you experience heavy or painful periods after stopping, speak to your healthcare provider for further advice.

Norimin is a combined pill, which contains both ethinylestradiol (oestrogen) and norethisterone (progestogen). Compared to other pills, Norimin may be better suited for women who prefer a fixed daily dose and who want the added benefit of relief from painful or heavy periods.

Some pills use different progestogens, which may result in different side effects. Speak with your healthcare provider to determine the best contraceptive for your individual needs.

It may help reduce acne in some women due to its hormone balance. The oestrogen in combined pills can help reduce the levels of androgens, which contribute to oily skin and breakouts.

However, Norimin is not primarily prescribed for acne. You should consult a healthcare professional if acne is your main concern, as this is not what it is normally prescribed for.

Yes, you can buy Norimin tablets online in the UK through GPhC-regulated pharmacies like Pharmacy Planet. You’ll need to complete an online health consultation reviewed by a UK-registered prescriber before receiving a prescription.

This service allows access to repeat prescriptions for those who already take Norimin and want a convenient refill option.
