The following information is a summary about Ovcon. It is not intended to replace a doctor's instructions.
What is Ovcon 35 (ethinyl estradiol and norethindrone)?
Ethinyl estradiol and norethindrone contains a combination of female hormones that
prevent ovulation (the release of an egg from an ovary). This medication also causes changes in
your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder
for a fertilized egg to attach to the uterus.
Ethinyl estradiol and norethindrone are used as contraception to prevent pregnancy. It is
also used to treat severe acne.
Ethinyl estradiol and norethindrone may also be used for other purposes not listed in this
medication guide.
What is the most important information I should know about Ovcon 35 (ethinyl estradiol and norethindrone)?
Do not use birth control pills if you are pregnant or if you have recently had a baby.
Do not use this medication if you have any of the following conditions: a history of
stroke or blood clot, circulation problems, a hormone-related cancer such as breast or uterine
cancer, abnormal vaginal bleeding, liver disease or liver cancer, or a history of jaundice caused
by birth control pills.
You may need to use back-up birth control, such as condoms or a spermicide, when you
first start using this medication. Follow your doctor's instructions.
Taking hormones can increase your risk of blood clots, stroke, or heart attack,
especially if you smoke and are older than 35.
Some drugs can make birth control pills less effective, which may result in pregnancy.

vitamins, minerals and herbal products. Do not start using a new medication without telling your
doctor.
What should I discuss with my healthcare provider before taking Ovcon 35 (ethinyl estradiol and norethindrone)?
This medication can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant, or if you miss two menstrual
periods in a row. If you have recently had a baby, wait at least 4 weeks before taking birth control
pills (6 weeks if you are breast-feeding).
Do not use this medication if you have:

you are breast-feeding a baby.
How should I take Ovcon 35 (ethinyl estradiol and norethindrone)?
Take this medication exactly as it was prescribed for you. Do not take larger amounts, or
take it for longer than recommended by your doctor. You will take your first pill on the first day
of your period or on the first Sunday after your period begins (follow your doctor's instructions).
You may need to use back-up birth control, such as condoms or a spermicide, when you
first start using this medication. Follow your doctor's instructions.
The 28-day birth control pack contains seven "reminder" pills to keep you on your regular
cycle. Your period will usually begin while you are using these reminder pills.
You may have breakthrough bleeding, especially during the first 3 months. Tell your
doctor if this bleeding continues or is very heavy.
Take one pill every day, no more than 24 hours apart. When the pills run out, start a new
pack the following day. You may get pregnant if you do not use this medication regularly. Get
your prescription refilled before you run out of pills completely.
The chewable tablet may be chewed or swallowed whole. If chewed,
drink a full glass of water just after you swallow the pill.
If you need to have any type of medical tests or surgery, or if you will be on bed rest, you
may need to stop using this medication for a short time. Any doctor or surgeon who treats you
should know that you are using birth control pills.
Your doctor will need to see you on a regular basis while you are using this medication.
Do not miss any appointments.
Store this medication at room temperature away from moisture and heat.
What happens if I miss a dose?
Missing a pill increases your risk of becoming pregnant.
If you miss one "active" pill, take two pills on the day that you
remember. Then take one pill per day for the rest of the pack.
If you miss two "active" pills in a row in week one or two, take two
pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use
back-up birth control for at least 7 days following the missed pills.
If you miss two "active" pills in a row in week three, or if you miss three
pills in a row during any of the first 3 weeks, throw out the rest of the pack and start a
new one the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill
every day until Sunday. On Sunday, throw out the rest of the pack and start a new one that day.
If you miss three "active" pills in a row during any of the first 3 weeks, throw out the rest of the pack and start a new pack on the same day if you are a Day 1
starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw
out the rest of the pack and start a new one that day.
If you miss two or more pills, you may not have a period during the month. If you miss a period for two months in a row, call your doctor because you might be
pregnant.
If you miss any reminder pills, throw them away and keep taking one pill per day until the
pack is empty. You do not need back-up birth control if you miss a reminder pill.
What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine.
Overdose symptoms may include nausea, vomiting, and vaginal bleeding.
What should I avoid while taking Ovcon 35 (ethinyl estradiol and norethindrone)?
Do not smoke while using birth control pills, especially if you are older than 35.
Smoking can increase your risk of blood clots, stroke, or heart attack caused by birth control
pills.
Birth control pills will not protect you from sexually transmitted
diseases--including HIV and AIDS. Using a condom is the only way to protect yourself from
these diseases.
