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.
While the "mini-pill" is more effective than certain
other methods of birth control (such as condoms, cervical cap, diaphragm),
it is less effective than combination hormone (estrogen and progestin)
birth control because it does not consistently prevent ovulation. It is
usually used by women who cannot take estrogen. To reduce the risk of
pregnancy, 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 (such as HIV, gonorrhea,
chlamydia).
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,
ask your doctor or pharmacist.
Take this medication by mouth as directed by your
doctor, usually once daily. Pick a time of day that is easy for you to
remember, and take your pill at the same time each day.
Taking this medication after your evening meal or at
bedtime may help if you have 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.
It is best to begin taking this medication on the first
day of your menstrual period. If you begin taking it on any other day, use
a backup form of non-hormonal birth control (such as condoms, spermicide)
for the first 48 hours to prevent pregnancy until the medication has enough
time to work.
Keep taking one tablet every day. After taking the last
tablet in a 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 irregular, or heavier/lighter than usual.
You may also have vaginal bleeding (spotting) between periods. Do not stop
taking your pills if this happens.
Pregnancy is more likely if you miss pills, start a new
pack late, or take your pill at a different time of the day than usual. If
you miss a pill, or take it 3 or more hours later than usual, or have
diarrhea, or vomit soon after taking a pill, use a backup method of birth
control (such as condoms, spermicide) every time you have sex for the next
48 hours.
Ask your doctor or pharmacist about how to switch from
other forms of hormonal birth control (such as patch, other birth control
pills) to this product. If any information is unclear, consult the Patient
Information Leaflet or your doctor or pharmacist.
Nausea, vomiting, headache, bloating, breast tenderness,
or weight gain may occur. Vaginal bleeding between periods (spotting) or
missed/irregular periods may occur. If any of these effects last or get
worse, tell your doctor or pharmacist promptly. If you miss 2 periods in a
row (or 1 period if the pill has not been used properly), contact your
doctor for a pregnancy test.

Some drugs may cause hormonal birth control to work less
well by decreasing the amount of birth control hormones in your body. This
effect can result in pregnancy. Examples include griseofulvin, modafinil,
rifamycins (such as rifampin, rifabutin), ritonavir, St. John's wort, drugs
used to treat seizures (such as barbiturates, carbamazepine, felbamate,
phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir,
nevirapine), among others.
Tell your doctor when you start any new drug, and
discuss if you should use reliable backup birth control. Also tell your
doctor if you have any new spotting or breakthrough bleeding, because these
may be signs that your birth control is not working well.
This medication may interfere with certain lab tests
(such as sex hormone-binding globulin, thyroid), possibly causing false
test results. Make sure lab personnel and all your doctors know you use
