You can usually expect the bleeding to settle within a few days of starting Primolut-N Tablet (norethisterone), although in some cases it may take up to a week. The medicine works by stabilising the womb lining, but ongoing bleeding can occur due to hormonal imbalance or irregular cycles. If the bleeding is heavy, prolonged, or not improving after 5 to 7 days, you should consult your doctor for review and possible adjustment of treatment. It is important to complete the prescribed course even if the bleeding stops earlier.

Fibroids are non-cancerous growths in the womb that can cause irregular bleeding or spotting. Primolut-N Tablet (norethisterone) is a hormonal treatment that helps control bleeding by stabilising the lining of the womb. In most women, spotting improves within 2 to 5 days of starting the medicine. Sometimes it may take up to one week for the bleeding to settle properly. If there is no clear improvement after a week, you should consult your doctor for further advice. This medicine can also help reduce heavy menstrual bleeding while you are taking it. However, it does not shrink fibroids or permanently cure them. Once the treatment is stopped, bleeding may return if the fibroids are still present. It is important to take the tablet exactly as prescribed and report any very heavy bleeding, dizziness, or worsening symptoms promptly to your doctor.

All three tablets, Primolut-N, Regestrone, and Meprate, contain the same active ingredient, Norethisterone 5 mg, and work in the same way to regulate the menstrual cycle or delay periods. The only difference is the brand name and manufacturer, not the effectiveness or dosage.

Since your period is 4 days late, the cause could be pregnancy, stress, thyroid issues, or other hormonal imbalances. Using Primolut N (norethisterone) without knowing the reason may complicate things. It is a prescription-only medication, and its effect may be unpredictable when periods are already late. Consult a gynaecologist for safe, effective guidance.

Spotting while taking these medications can sometimes occur due to hormonal fluctuations, individual response to treatment, or underlying gynaecological conditions. Because both medicines influence bleeding and hormone balance, it is important not to adjust or continue them on your own. Persistent or unusual spotting should be evaluated by a gynaecologist, who can review your medical history, current cycle, and treatment plan to recommend the safest next steps.

Primolut N is a hormonal medicine, and after stopping it, withdrawal bleeding (similar to a period) usually begins within 2 to 7 days. However, the exact timing can vary depending on your individual hormonal cycle and ovulation status. Since follicle rupture has already occurred, your natural cycle may also influence when bleeding starts. It’s best to wait a few days, and if your period is delayed or you need guidance on regulating your cycle, consult a doctor for safe and personalised advice.
