Frequently asked questions

Below are answers to some commonly asked questions about norethindrone oral tablet and its dosage.

Can norethindrone be used to stop my period? If so, what is the dosage?

Norethindrone is not approved to stop or delay your period. Instead, it’s used to treat symptoms of a hormonal imbalance, including having no periods, in certain females. To learn more about the dosage for this use, see the “Dosage of norethindrone” section above.

Norethindrone is a progestin hormone. It promotes regular growth of your uterine lining, which is part of a typical menstrual cycle.

While taking norethindrone, some people may experience early or late periods as a side effect. Some people may also experience spotting between periods.

If you have questions about your period and norethindrone, talk with your doctor.

Is norethindrone taken long term?

It depends on the reason you’re taking norethindrone.

For endometriosis, you usually take norethindrone for 6–9 months or when breakthrough bleeding becomes bothersome. With certain other symptoms, you may only need to take norethindrone for 5–10 days during your menstrual cycle.
