What is Micronor?

Micronor (generic name Norethindrone) is a pill taken once daily to prevent pregnancy. It must be taken at the same time every day. If Micronor birth control is taken more than 3 hours late, it is not effective.

What is Micronor used for?

Micronor is used to prevent pregnancy. Micronor birth control works in 3 ways to stop pregnancy:

  • It stops the egg from being released from your ovaries during some menstrual cycles.
  • It thickens mucus in the vagina to make it difficult for sperm to swim up to the womb
  • It changes the lining of the womb to make it harder for a fertilized egg to stick

What are the side effects of Micronor?

The most common Micronor side effect is abnormal menstural bleeding (including spotting or irregular periods). Less frequent Micronor side effects include nausea or feeling sick to your stomach, vomiting, dizziness, headache, or sore breasts. Rare Micronor side effects include weight gain, acne, extra hair on body or face, yellowing of skin or eyes (jaundice), feeling tired, and tubal pregnancy. Call your doctor immediately if you are experiencing side effects from Micronor.

What you should know before using Micronor

Micronor does not stop the transmission of sexually transmitted diseases (it will not protect against HIV/AIDS, herpes, gonorrhea, or genital warts). Do not take Micronor if there is any chance you may be pregnant. Do not use it if you have unusual bleeding between periods. If you have liver problems (including liver disease, benign or cancerous liver tumors), do not use Micronor birth control. Tell your doctor if you have any of the following medical problems before taking Micronor:

  • Breast lumps or breast cancer
  • Diabetes or high blood sugar
  • If you are a cigarette smoker
  • Migraine headaches
  • Depression or sadness
  • Uterine fibroids (or tumors in the uterus or womb)
  • Are currently pregnant or nursing
  • Are planning to undergo surgery

Micornor may increase the risk of certain types of cancers (e.g. breast cancer, ovarian cysts). Tell your doctor about all other medications (especially anti-seizure medicine) and over-the-counter supplements you are using before starting Micronor.
