Primolut N Tablets: Uses, Dosage, Side Effects, Precautions and More
Primolut N tablets are a hormonal medicine commonly prescribed for certain menstrual and gynecological problems. The active ingredient in Primolut N is norethisterone 5 mg, a synthetic progestogen with properties similar to the natural hormone progesterone.
Doctors may prescribe Primolut N for problems such as heavy or irregular menstrual bleeding, absence of periods in certain situations, endometriosis, premenstrual symptoms, and postponement of menstruation. However, the appropriate dose and duration depend on the reason for treatment and the individual's medical history.
«Important: Primolut N is a prescription hormonal medicine. It should be used only according to the instructions of a doctor or qualified healthcare professional.»
What Is Primolut N Tablet?
Primolut N is a tablet containing 5 mg of norethisterone. Norethisterone belongs to a group of medicines called progestogens. It acts similarly to progesterone and can influence the lining of the uterus and the menstrual cycle.
Because hormonal medicines can affect different people differently, Primolut N should not be taken simply because someone else has used it for similar symptoms.
What Is Primolut N Used For?
Primolut N may be prescribed for several menstrual and gynecological conditions. Depending on the approved indication and local prescribing information, these include:
- Heavy or abnormal menstrual bleeding
- Irregular menstrual bleeding
- Painful periods
- Premenstrual symptoms
- Absence of menstruation in selected cases
- Endometriosis
- Postponement of menstruation
- Certain other hormone-related menstrual disorders
The medicine does not treat every cause of abnormal bleeding. If bleeding continues despite appropriate treatment, an underlying cause may need to be investigated by a healthcare professional.

Primolut N for Delaying Periods
Norethisterone can be prescribed to temporarily delay menstruation. For this purpose, it generally needs to be started at least three days before the expected beginning of the period. The period commonly returns within a few days after treatment is stopped, although the timing can vary between individuals.
Importantly, norethisterone is not a contraceptive. Taking Primolut N to postpone a period does not protect against pregnancy. Appropriate contraception should therefore be used when pregnancy is possible.
How Does Primolut N Work?
Primolut N contains norethisterone, which has progesterone-like effects. Hormonal changes produced by norethisterone can affect the uterine lining and help regulate or temporarily suppress menstrual bleeding.
The exact effect depends on why the medicine is prescribed, the dose, and the timing within the menstrual cycle.
Primolut N Dosage
There is no single dose that is suitable for everyone. The dosage depends on the condition being treated.
For example, official product information describes different dosing schedules for abnormal uterine bleeding, premenstrual symptoms, endometriosis, and postponement of menstruation.
For period delay, professional guidance states that norethisterone 5 mg may be prescribed three times daily, beginning at least three days before the expected period.
Do not increase the dose, take extra tablets, or continue treatment longer than prescribed.
How to Take Primolut N Tablets
Take Primolut N exactly as directed by your doctor.
The tablets should generally be swallowed whole with liquid. If you forget a dose, follow the instructions provided by your doctor or pharmacist rather than taking extra tablets to compensate unless specifically advised to do so.
Try to take your doses consistently at the prescribed times.

- Headache

Who Should Not Take Primolut N?
Primolut N is not suitable for everyone. According to the product information, it should not be used in certain circumstances, including pregnancy or suspected pregnancy, breastfeeding, a history of certain blood-clot-related conditions, certain types of migraine with neurological symptoms, severe liver disease, certain liver tumors, and some hormone-sensitive cancers.
People with other medical conditions may also require special assessment before using it.
Always tell your doctor about your medical history before starting Primolut N.
Primolut N and Pregnancy
Primolut N should not be taken during pregnancy or when pregnancy is suspected. If you think you may be pregnant while taking the medicine, contact your healthcare professional for advice.
Primolut N should also not be used while breastfeeding according to the cited product information.
Primolut N and Other Medicines
Some medicines can interact with norethisterone or alter its effects. The product information lists medicines such as certain antiepileptic medicines, cyclosporine, theophylline, and tizanidine among medicines that may require consideration.
Always tell your doctor or pharmacist about all prescription medicines, over-the-counter medicines, and supplements you are taking.
Is Primolut N a Contraceptive?
No. Primolut N should not be relied upon as a contraceptive.
This particularly important when the medicine is being used to delay menstruation. Norethisterone used for period delay does not provide reliable protection against pregnancy.
Can Primolut N Be Used to Stop Heavy Periods?
Norethisterone is used in some treatment plans for heavy or abnormal menstrual bleeding. It can help control bleeding by acting on the uterine lining.
However, heavy bleeding can have many causes, including hormonal problems, fibroids, polyps, pregnancy-related conditions, and other medical issues. Persistent or unusually heavy bleeding should therefore be assessed rather than repeatedly treated without finding the cause.
Primolut N and Endometriosis
Norethisterone is also used in some treatment plans for endometriosis, a condition in which tissue similar to the lining of the uterus grows outside the uterus.
Hormonal treatment can help control symptoms by changing hormonal stimulation of this tissue. The treatment plan for endometriosis should be individualized by a healthcare professional.
