Primolut-N (Norethisterone) for Period Delay: Mechanism, Dosage Regimen, and Important Considerations

Primolut-N (norethisterone) is a synthetic progestin used in hormonal therapy, including menstruation postponement.

Mechanism

Norethisterone mimics natural progesterone, stabilizing the uterine lining and preventing its shedding. It interferes with normal hormonal shifts (estrogen surge, ovulation) that trigger menstruation. Continuous progestin supply suppresses these shifts, delaying period onset.

Typical Dosage for Period Delay

• Start 3–4 days before expected period (or as directed by doctor).
• Take 1 tablet daily (usually evening).
• Continue for desired delay duration (few days up to max 10–14 days).
• After stopping, menstruation usually returns within a few days (withdrawal bleeding).

Crucial: Follow prescribed dosage/duration exactly. Consult your doctor before use, disclosing medical conditions and medications to avoid interactions.
