What are norethindrone tablets?

NORETHINDRONE (Ortho-Micronor® or Errin™ or Jolivette™, Nor-QD® or Camila™, Norlutin®, Aygestin®) is used as a birth-control pill (to prevent an unwanted pregnancy) or a hormone treatment, depending on the brand you have been prescribed. Norethindrone acts like the natural hormone progesterone. Natural progesterone is essential to normal functioning of the female reproductive system. Norethindrone also helps to treat an irregular menstrual cycle, lack of menstrual periods, or abnormal uterine bleeding caused by a hormonal imbalance. Norethindrone tablets are available from several pharmaceutical manufacturers; however, not all brands are substitutable for one another.

What should my health care professional know before I take norethindrone?

They need to know if you have any of these conditions:

  • blood vessel disease, blood clotting disorder, or suffered a stroke
  • breast, cervical, or vaginal cancer
  • diabetes
  • heart, kidney or liver disease
  • high blood lipids or cholesterol
  • mental depression
  • migraine
  • seizures (convulsions)
  • vaginal bleeding
  • an unusual or allergic reaction to norethindrone, other hormones, medicines, foods, dyes, or preservatives
  • pregnant or trying to get pregnant
  • breast-feeding

How should I take this medicine?

Take norethindrone tablets by mouth. Follow the directions on the prescription label. Swallow the tablets with a drink of water. Take your doses at regular intervals. Do not take your medicine more often than directed.

For treating absent or irregular menses or for controlling unusual bleeding: Take norethindrone from day 5 to day 25 of the cycle.

For treating endometriosis: Before you start taking these pills decide what is a suitable time of day and always take them at the same time of day. Your doctor may instruct you to take norethindrone every day for 2 weeks, and from there may increase your dosage to get the proper effect. You will probably take the medication every day for 6 to 9 months.

As a contraceptive (birth control method): Before you start taking these pills decide what is a suitable time of day and always take them at the same time of day. Norethindrone birth control tablets should be taken every day, without breaks between packs.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

What if I miss a dose?

For general use: If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

For contraceptive use: Every time you miss a dose, or take a dose late by > 3 hours, your chance of getting pregnant increases. Try not to miss a dose. When one pill is missed (even if only 3 hours late), take the missed pill as soon as possible and continue taking a pill each day at the regular time (a backup method of birth control, like a condom or spermicide, should be used for the next 48 hours). Whenever > 1 dose is missed, additional contraception should be used for the rest of your pill pack until menses occurs. You should also contact your health care professional for instruction whenever more than 1 dose has been missed.
