NORETHINDRONE (CONTRACEPTIVE) - ORAL
COMMON BRAND NAME(S): Micronor, Nor-Q-D
USES: This medication is used to prevent pregnancy. It is often referred to as the "mini-pill" because it does not contain any estrogen. Norethindrone (a form of progestin) is a hormone that prevents pregnancy by changing the womb and cervical mucus to make it more difficult for an egg to meet sperm (fertilization) or for the fertilized egg to attach to the wall of the womb (implantation). Regular use of the "mini-pill" prevents the release of an egg (ovulation) in about half of the women who use it.
While the "mini-pill" is more effective than certain other methods of birth control (e.g., condoms, cervical cap, diaphragm), it is less effective than estrogen/progestin birth control because it does not consistently prevent ovulation. It is usually used by women who cannot take estrogen. For the most effective benefit, it is very important to take this medication exactly as prescribed.
Using this medication does not protect you or your partner against sexually transmitted diseases (e.g., HIV, gonorrhea).
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
Norethindrone may also be used to help decrease pain and blood loss from a certain menstrual condition (heavy/painful periods due to endometriosis) and to help make your periods more regular.
HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using this product and each time you get a refill. The leaflet contains very important information on when to take your pills and what to do if you miss a dose. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth with or without food, usually once daily or as directed by your doctor. For this medication to be effective, you must take it at the same time each day. Pick a time of day that is easy for you to remember, and take your pill at the same time each day. Missing a pill, taking it more than 3 hours late, or starting a new pack late will increase your risk of becoming pregnant. If you miss a pill or take this medication 3 or more hours later than usual, use a backup method of birth control (e.g., condom, spermicide) every time you have sex for the next 2 days.
Taking this medication after your evening meal or at bedtime may help if you have any stomach upset or nausea with the medication. You may choose to take this medication at another time of day that is easier for you to remember. No matter what dosing schedule you use, it is very important that you take this medication at the same time each day, 24 hours apart. Ask your doctor or pharmacist if you have any questions.
Continue taking one tablet every day. After taking the last tablet in your old pack, start a new pack the next day. There is no break between packs, and you do not take any "reminder" tablets (tablets without medication). Your periods may be early or late, shorter or longer, heavier or lighter than normal. You may also have some spotting between periods. Do not stop taking your pills if this happens.
If you vomit within 4 hours after taking this medication or have diarrhea, use a back-up method of birth control (e.g., condoms, spermicide) every time you have sex for the next 2 days.
If you continue to have regular menstrual periods while on this medication, you may be ovulating. This medication might still prevent pregnancy even if you are ovulating. Consult your doctor for more information, and ask about your risk of pregnancy and the possible use of other forms of birth control.
If this is the first time you are using this medication and you are not switching from another form of hormonal birth control (e.g., patch, other birth control pills), take the first pill in the pack on the first day of your period. Use an additional form of birth control for the first 2 days if you are instructed to start this medication on any other day.
Ask your doctor or pharmacist for information about how to switch from other forms of hormonal birth control (e.g., patch, other birth control pills) to this product. If any of this information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.
