Norethindrone/Norethisterone 5mg Uses

Norethindrone/Norethisterone 5mg is prescribed to:

• Prevent pregnancy as a part of hormonal contraceptive therapy.
• Regulate the menstrual cycle and reduce menstrual bleeding.

• Used as a part of hormone replacement therapy (HRT) for menopausal women.

How Does Norethindrone/Norethisterone 5mg Work

Norethindrone is a synthetic form of progesterone, a natural female hormone. It works by mimicking the action of progesterone in the body, which helps to regulate the menstrual cycle, inhibit ovulation, and alter the lining of the uterus to prevent pregnancy. Additionally, it affects the cervical mucus, making it thicker and more difficult for sperm to enter the uterus.

In combination with estrogen, Norethindrone is also used in hormone replacement therapy (HRT) to prevent endometrial hyperplasia (thickening of the uterine lining), which can occur when estrogen is used alone.

How to Use Norethindrone/Norethisterone 5mg

• Dosage: The usual dose of Norethindrone 5mg is one tablet taken once a day, as directed by your healthcare provider.
• Administration: Swallow the tablet whole with a glass of water. It can be taken with or without food.
• Frequency: Take the medication at the same time every day to ensure consistency.
• Duration: For contraception, it is generally taken every day without a break. For other conditions like endometriosis or abnormal bleeding, your doctor will specify the duration of treatment.

Important Notes

• If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses at once to make up for a missed dose.
