Oral contraceptive tablets are used to prevent pregnancy. They may also be
used to treat painful or heavy menstruation.
Carefully read the patient information pamphlet included with your
prescription container before using this product.
In order to prevent pregnancy this medication must be taken once every 24
hours at the same time each day as prescribed. Never let your supply of
tablets run out; always keep an extra month's supply on hand.
It has been recommended that an additional method of birth control be used
during the first 3 weeks of taking this medication to prevent pregnancy.
Your physician may make other recommendations.
Always have another form of birth control available in case you miss doses
of this medication. Do not skip tablets even if you do not have sexual
intercourse very frequently.
Take the first tablet on the first day of menstrual bleeding, then take one
tablet daily until the tablet dispenser is empty. Without missing a day,
start taking one tablet daily from a new tablet dispenser even during your
menstrual period. You will take one tablet daily every day of the year with
no interruptions when this medication is used for contraception.
Your periods may become very irregular while taking this medication.
Spotting and breakthrough bleeding (light bleeding midcycle) may occur.
Check with your physician if vaginal bleeding lasts for an unusually long
time. If you haven't had a period within 45 days of your last period notify
your physician because a pregnancy test should be done.
Do not take this medication if you think you are pregnant. It will not stop
the pregnancy from continuing. Consult your physician.
MISSED DOSES - If you miss a tablet the safest thing to do is to stop
taking the medication and use a different method of birth control until
menstrual flow begins or it has been demonstrated that you are not
pregnant. Your physician may make other recommendations.
CHECK UPS - It is important to have regular check ups by your physician
while you are taking oral contraceptives. Your physician may wish to
examine you once or twice a year or more frequently according to your own
medical history and response to this medication.
SIDE EFFECTS - Micronor contains a hormone called a progestin. It may have
fewer side effects than products that also contain estrogens but this is
controversial. Side effects caused by a blood clot occur very rarely but
can be very serious; these include stroke and heart attack. If any of the
following occur, get emergency help immediately: chest pain, coughing
blood, sudden shortness of breath; pain in groin or leg (especially in
calf); severe or sudden headache; sudden changes in vision or speech;
unexplained weakness or numbness in arm or leg; severe abdominal pain.
Contact your physician if these rare side effects occur: changes in vision
or bulging eyes, major changes in vaginal bleeding, frequent or painful
urination, breast lumps or secretions, mental depression, fainting,
yellowing of the skin or eyes (jaundice), and persistent pain or lumps in
the abdomen.
Some side effects are more common and less serious and may decrease after
the first three months of using this medication. These include acne,
abdominal bloating or cramping, nausea, mood changes, changes in appetite,
weight gain, swelling of feet and ankles, breast tenderness, skin and hair
changes and unusual tiredness. Discuss any persistent or bothersome side
effects with your physician so that treatment can be adjusted to your needs
if necessary.
In some patients this medication may cause swelling, tenderness or bleeding
of the gums. Good oral care such as regular brushing and flossing of the
teeth as well as massaging of the gums is recommended. Consult your dentist
or physician if problems occur.
SMOKING - Cigarette smoking increases the risk of serious adverse effects
on the heart and blood vessels from oral contraceptive use; oral
contraceptive users should not smoke.
If you have vomiting or diarrhea the effectiveness of the oral
contraceptive tablets may be decreased. Use an additional method of birth
control as well until you can discuss this with your physician.
INTERACTIONS - Some other medications may decrease the effectiveness of
oral contraceptives or produce an increase in side effects. Laboratory test
results may also be affected. Tell your physician, pharmacist and dentist
that you are taking an oral contraceptive.
If you wish to become pregnant it is usually recommended that you stop
taking the oral contraceptive and delay pregnancy until at least one
spontaneous menstrual period has occurred. Discuss this with your
physician. Another method of contraception should be used in the meantime.
If you wish to take oral contraceptives while breast-feeding, discuss this
with your physician.
SURGERY - It is usually recommended that you stop taking oral
contraceptives four weeks before elective surgery as this medication may
increase the risks of blood clots, stroke and heart attacks. Another form
of contraception should be used.
Oral contraceptives do not protect you against sexually transmitted
diseases including AIDS. Use of latex condoms will help reduce risk of
infection.
