Prosu and NORiNa: Ovulation or Menstrual Induction? - Obstetrics and Gynecology

Share to:

Are you asking if it is an ovulation medication?


Doctor, I haven't had my period for a long time.
I went to see a doctor the day before yesterday.
The doctor prescribed Prosu tablets and NORiNa tablets 5mg.
Can you tell me if these are for inducing ovulation or for bringing on my period?

Hello, this is a medication to induce menstruation, not an ovulation medication.

More Info


Prosu Tab and NORiNa Tablets are both medications that are often used in the context of menstrual irregularities, but they serve different purposes. Understanding their roles can help clarify whether they are intended for ovulation induction or menstrual induction.

Prosu Tab typically contains clomiphene citrate, a medication commonly used to induce ovulation in women who have difficulty ovulating on their own. It works by blocking estrogen receptors in the hypothalamus, which in turn stimulates the release of hormones necessary for ovulation. This medication is particularly useful for women with conditions like polycystic ovary syndrome (PCOS) or other ovulatory disorders. If your doctor prescribed Prosu Tab, it is likely aimed at helping you ovulate, especially if you have been experiencing irregular or absent menstrual cycles.

NORiNa Tablets, on the other hand, contain norethisterone, a synthetic form of progesterone. This medication is often used to regulate menstrual cycles, particularly in cases where menstruation is absent or irregular. Norethisterone works by mimicking the effects of natural progesterone in the body, which helps prepare the uterine lining for a potential pregnancy and can induce a menstrual period when taken for a specific duration. If your doctor prescribed NORiNa, it is likely intended to help bring on your period if you have not menstruated for a while.

Given your situation of not having your period for a long time, the combination of Prosu Tab and NORiNa Tablets suggests a dual approach. The Prosu Tab may be aimed at stimulating ovulation, while the NORiNa Tablets may be intended to induce menstruation. This combination can be particularly useful in managing conditions like PCOS, where both ovulation and menstrual regulation are concerns.

It is essential to follow your doctor's instructions regarding the dosage and duration of these medications. Additionally, it is crucial to monitor your body's response to the treatment. If you experience any unusual side effects or if your menstrual cycle does not normalize after completing the prescribed course, you should consult your healthcare provider for further evaluation.

In summary, Prosu Tab is primarily used for ovulation induction, while NORiNa Tablets are used for menstrual induction. The combination of these medications can be beneficial for women experiencing irregular menstrual cycles, particularly in the context of conditions like PCOS. Always consult your healthcare provider for personalized advice and to ensure that your treatment plan is appropriate for your specific health needs.
