About Norimin Contraceptive Pill

Norimin is a combined oral contraceptive pill (often referred to as “the Pill”) used to prevent pregnancy. Each tablet contains 1mg of norethisterone (a progestogen) and 35 micrograms of ethinylestradiol (an estrogen). These synthetic hormones mimic the body’s natural cycle to provide reliable protection against conception. Norimin works in three ways: it prevents the ovaries from releasing an egg (ovulation), thickens the cervical mucus to block sperm, and thins the womb lining to prevent a fertilised egg from implanting.

What Is Norimin Used For?

Norimin is primarily used for female contraception. Beyond preventing pregnancy, many women find that Norimin helps regulate their menstrual cycle, making periods lighter, more predictable, and less painful. It is particularly effective for those who require a consistent dose of hormones to maintain cycle control.

Who Is Norimin Suitable For?

Norimin is suitable for most healthy women of childbearing age. However, a medical consultation is required to ensure it is safe for you.Do not take Norimin if you:

  • Are allergic to norethisterone, ethinylestradiol, or any other ingredients.
  • Have (or have ever had) a blood clot in the legs (DVT), lungs (PE), or other organs.
  • Have a history of heart attack, stroke, or severe migraine with aura.
  • Have severe liver disease or breast/genital cancer.
  • Are currently pregnant or breastfeeding.

Speak to a healthcare professional before use if you:

  • Smoke (especially if over age 35).
  • Have high blood pressure or diabetes.
  • Suffer from Crohn’s disease or Ulcerative Colitis.
  • Have systemic lupus erythematosus (SLE).

How to Take Norimin

  1. Take one pill at the same time every day to ensure maximum effectiveness.
  2. Swallow the tablet whole with water; it can be taken with or without food.
  3. Follow the arrows on the blister strip to stay on track.
  4. After 21 days, stop taking the pills for exactly 7 days.
  5. Always start your new pack on time, regardless of whether your bleeding has stopped.

If you start Norimin on Day 1 of your period, you are protected immediately. If starting on Day 2-5, use additional contraception (like condoms) for the first 7 days.

Possible Side Effects of Norimin

Common side effects may include:

  • Nausea and stomach aches
  • Weight changes
  • Headaches or mood swings
  • Breast tenderness or enlargement

Uncommon/Rare:

  • Fluid retention
  • Changes in libido (sex drive)
  • Skin rashes or brown patches on the face (chloasma)

Hormonal contraceptives slightly increase the risk of blood clots. Seek immediate medical help if you experience sudden leg swelling, chest pain, or difficulty breathing.

Warnings and Precautions

  • Norimin does not protect against STIs; use a condom for barrier protection.
  • Vomiting or severe diarrhoea can stop the pill from working. Follow “missed pill” instructions if this occurs.
  • Regular blood pressure and weight checks are recommended while on the Pill.

Storage Instructions

  • Store below 25°C in a dry place.
  • Keep the tablets in the original package to protect them from light and moisture.
  • Keep out of sight and reach of children.

Important Information

  • Always read the patient information leaflet before starting a new pack.
  • If you miss a pill by more than 12 hours, your contraceptive protection may be reduced.
  • Certain medications (like those for epilepsy or St. John’s Wort) can interfere with Norimin.
