What is the drug Primolut N used for?

Primolut N, containing the active ingredient norethisterone, is a synthetic form of the hormone progesterone used to treat a range of gynecological conditions. By artificially maintaining high levels of this hormone, the medication can regulate the menstrual cycle and manage specific reproductive health issues.

What is Primolut N and how does it work?

Primolut N is a progestogen-based medication containing norethisterone, a synthetic form of the naturally occurring female hormone progesterone. Progesterone plays a crucial role in maintaining the uterine lining (endometrium) throughout the menstrual cycle. A drop in progesterone levels at the end of the cycle triggers menstruation. By mimicking the effects of natural progesterone, Primolut N keeps these hormone levels high, preventing the breakdown of the endometrium and thereby managing or postponing menstruation. The therapeutic application of Primolut N is based on its ability to stabilize the uterine lining and suppress ovulation in certain dosages.

Primary uses for Primolut N

Primolut N is a versatile medication with several key applications in women's health. It is not an everyday contraceptive pill and should only be used under a doctor's supervision.

• Dysfunctional Uterine Bleeding (Heavy Periods): One of the most common uses is to control heavy or prolonged menstrual bleeding, also known as menorrhagia. By stabilizing the uterine lining, it helps to reduce the amount of blood lost during a period.
• Endometriosis: This condition, where uterine tissue grows outside the womb, can cause severe pain and heavy periods. Primolut N is used to prevent this endometrial tissue from growing too rapidly, which helps alleviate the associated pain and inflammation. Continuous use suppresses ovulation and menstruation.
• Postponing Menstruation: For special events, vacations, or religious reasons, Primolut N can be used to delay a period. It must be started a few days before the expected start date, and a withdrawal bleed typically occurs 2–3 days after stopping the medication.
• Amenorrhea (Absence of Periods): For women with absent menstrual periods, Primolut N can be used to regulate the cycle. In cases of secondary amenorrhea, it is often used in combination with estrogen.
• Premenstrual Syndrome (PMS): Primolut N may be prescribed to relieve severe symptoms of PMS, such as headaches, breast tenderness, bloating, and mood swings.
• Menopause Hormonal Therapy (MHT): In some cases, Primolut N is used in combination with estrogen as part of MHT to manage menopausal symptoms.

Dosage and administration

The appropriate dosage and duration of Primolut N treatment depend on the medical condition and individual factors. It is essential to follow a doctor's instructions precisely and to complete the full course of treatment. The tablets can be taken with or without food, along with a full glass of water.

Side effects and contraindications

Like any hormonal medication, Primolut N can cause side effects. These may be more common initially and often improve with continued use.

Common side effects

• Headaches and Migraines: Many women report experiencing headaches, and for some, an increase in migraine frequency.
• Gastrointestinal Issues: Nausea, bloating, and stomach upset are frequently reported.
• Fluid Retention: The medication can cause fluid retention, which may lead to general swelling (oedema), swollen ankles, or weight gain.
• Breast Tenderness and Enlargement: Some individuals experience breast tenderness and swelling.
• Mood Changes: Changes in mood, including depression and irritability, have been reported.
• Irregular Bleeding: Breakthrough bleeding or spotting between periods can occur, especially in the early stages of treatment.

Rare but serious side effects

• Thromboembolism: Primolut N can increase the risk of blood clots (thrombosis), especially with higher doses or certain risk factors. Individuals should seek immediate medical attention if they experience symptoms like severe chest pain, shortness of breath, or unexplained leg pain and swelling.
• Liver Issues: In very rare cases, the medication may be associated with liver tumors, which can cause severe abdominal pain.
• Vision Problems: Changes in vision, such as blurred vision or double vision, should be reported to a doctor immediately.

Contraindications

Primolut N is not suitable for everyone. It is contraindicated in individuals with:

• Known or suspected pregnancy or breastfeeding
• History of thromboembolic diseases (e.g., blood clots)
• Severe liver disease or tumors
• Hormone-dependent cancers (e.g., breast or uterine cancer)
• Unexplained abnormal vaginal bleeding
• Migraines with neurological symptoms
• Severe diabetes with vascular complications
