About Primolut N
What is Primolut N?
Primolut N is a period delay tablet containing Norethisterone 5 mg per tablet, made by Bayer, Germany. Norethisterone is a synthetic progestin hormone that acts like the natural progesterone in a woman's body.
It works by keeping hormone levels steady so the lining of the womb stays in place and does not shed as a period, for as long as you keep taking it. When you stop the medicine, hormone levels drop, the womb lining sheds, and your period follows within 2-3 days. Because of this mechanism, Primolut N is a popular period delay choice for special occasions. Many people refer to Primolut N as a period-postponement or period-stopping tablet, since it lets them plan around their cycle.
What is Primolut N used for?
Period delay tablets Primolut N (Norethisterone) have several uses, not only postponing a period.
Delaying a period
Used to push back the day your period starts during important occasions such as travel, exams, or a wedding — the most common use.
Regulating irregular periods and absent periods
Helps regulate hormones in women with irregular cycles or absent periods (amenorrhea), under the guidance of a pharmacist or doctor.
Abnormal uterine bleeding
Used to help control spotting or unusually heavy menstrual bleeding.
Premenstrual syndrome and endometriosis
Norethisterone is also used to help manage premenstrual syndrome (PMS) and endometriosis in some cases.
How to take Primolut N and dosage
Taking it to delay a period
The usual dose is 1 tablet of Primolut N (Norethisterone 5 mg) three times a day, starting about 3 days before your period is due and continuing throughout the time you want to delay it. After you stop, your period arrives within 2-3 days.
How to take it
Take the tablets after food with water and try to take them at the same times each day. When using it to delay a period, you should not continue for more than about 10-14 days for safety.
For regulating cycles or treating other conditions, the dose and duration may differ — consult a pharmacist or doctor for advice that suits you.
Side effects of Primolut N
Most people taking period delay tablets Primolut N tolerate them well. Possible side effects, usually mild, include:
- Nausea, dizziness, or headache
- Breast tenderness
- Mood changes
- Spotting or breakthrough bleeding while taking the medicine
- Bloating or slight weight changes
These usually settle after stopping the medicine. If you notice rare but serious symptoms such as a painful swollen leg, chest pain, difficulty breathing, or an unusually severe headache — possible signs of a blood clot — stop the medicine and see a doctor immediately.
To reduce nausea, take the tablets after food with water. If mild side effects interfere with daily life or last longer than expected, you can always ask a pharmacist for further advice.
Contraindications and precautions
Do not use Primolut N in the following cases:
- You are pregnant or think you may be pregnant
- You have a history of blood clots in veins or arteries
- You have severe liver disease
- You have unexplained vaginal bleeding
- You have or have had a hormone-sensitive cancer such as breast cancer
People with diabetes, high blood pressure, migraine, heart disease, or who smoke should use it with caution and consult a pharmacist or doctor first. This period delay medicine is not a contraceptive and should not be used in place of birth control.
Primolut N vs other period delay medicines
Common period delay medicines are usually progestin hormones, but with different active ingredients.
- Provera (Medroxyprogesterone) — another progestin used to regulate hormones and delay periods, often for ongoing irregular cycles.
In short: for short-term period delay on a special occasion, Primolut N (Norethisterone) is a popular choice started 3 days before your period, while Provera suits cycle regulation under a doctor's guidance. If you are unsure which to choose, ask a pharmacist to match it to your needs.
Can Primolut N be taken with other medicines?
Some medicines can interfere with how Primolut N works, especially those that stimulate liver enzymes, which can lower Norethisterone levels and reduce its period-delaying effect.
- Some antibiotics such as rifampicin
- Some anti-epileptic medicines such as carbamazepine, phenytoin
- The herbal remedy St John's Wort
If you take any regular medicines or herbal products, tell a pharmacist or doctor before starting period delay tablets for the best safety and effectiveness.
In general, short-term use of Primolut N to delay a period does not cause problems with common medicines, but if you are treating an ongoing condition, always give your pharmacist a full list of your medicines and supplements for safety.
How fast does Primolut N work and when does the period return?
Primolut N begins to support the womb lining as soon as you start taking it, but for it to delay your period effectively you should start about 3 days before your period is due. Starting too late, after the period has already begun, may not delay it fully.
Once you stop, hormone levels fall and your period usually returns within 2-3 days, which is normal with this period delay medicine.

Frequently Asked Questions
Generally Primolut N can delay a period for up to about 10-14 days while you keep taking it. Delaying longer is not recommended, and if you want to delay regularly you should consult a pharmacist or doctor first. Delaying for too long may increase the chance of spotting while you take it.
Primolut N is not a contraceptive and cannot be used to prevent pregnancy. If you need birth control, use a suitable contraceptive method separately and ask a pharmacist for advice.
If you miss a dose, take it as soon as you remember. But if it is almost time for the next dose, skip the missed one and continue as normal — do not double up. Missing doses may cause spotting or an incomplete delay of your period. Missing several doses in a row may weaken the effect, and your period may come earlier than planned.
For the best result you should start about 3 days before your period is due. If you start after it has already begun, the medicine may reduce the flow somewhat but will not delay the cycle completely.
Some people may gain a little weight or feel bloated during use, which is usually temporary and returns to normal after stopping — it does not cause permanent weight gain. If you are worried about weight, ask a pharmacist. Drinking enough water and cutting back on salty food can help reduce water retention during use.
Primolut N period delay tablets are affordably priced. You can see the current price per box (30 tablets) on this product page, with delivery across Thailand.
People with high blood pressure, migraine, diabetes, or heart disease should use Primolut N with caution and always consult a pharmacist or doctor first to assess suitability and safety for them individually.
Using Primolut N for short-term period delay does not affect long-term fertility. Once you stop, your cycle returns to normal. If you have concerns about future pregnancy, consult a doctor.
When Norethisterone is used to regulate cycles or manage hormone problems, how long it takes to see results depends on the symptoms and dose, and may require several days to several weeks of continuous use. Follow the advice of a pharmacist or doctor.
