Before taking this medicine

Taking this medicine can increase your risk of blood clots, stroke, or heart attack. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight. Your risk of stroke or blood clot is highest during your first year of taking birth control pills. Your risk is also high when you restart this medicine after not taking it for 4 weeks or longer.

Smoking can greatly increase your risk of blood clots, stroke, or heart attack. Your risk increases the older you are and the more you smoke. You should not take combination birth control pills if you smoke and are over 35 years old.

Do not use if you are pregnant. Stop using this medicine and 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.

How should I take Portia?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Take your first pill on the first day of your period or on the first Sunday after your period begins. You may need to use back-up birth control, such as condoms or a spermicide, when you first start using Portia. Follow your doctor's instructions.

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 take one pill daily. Get your prescription refilled before you run out of pills completely.

Some birth control packs contain seven "reminder" pills to keep you on your regular cycle. Your period will usually begin while you are using these reminder pills.

You should chew the chewable tablet (pill) and then swallow it with a glass of water, or if you prefer you should swallow the chewable tablet (pill) whole. Take it on an empty stomach.

Use a back-up birth control if you are sick with severe vomiting or diarrhea.

You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.

If you need major surgery or will be on long-term bed rest, you may need to stop using this medicine for a short time. Any doctor or surgeon who treats you should know that you are using birth control pills.

While taking birth control pills, you will need to visit your doctor regularly.

Store at room temperature away from moisture, heat, and light.

What happens if I miss a dose?

Follow the patient instructions provided with your medicine. 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 1 or 2, 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 3, throw out the rest of the pack and start a new pack 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 pack that day.

If you miss three active pills in a row in Week 1, 2, or 3, 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 pack that day.

If you miss two or more active 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 a reminder pill, throw it away and keep taking one reminder pill per day until the pack is empty.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include nausea, vomiting, and drowsiness.

What should I avoid while taking Portia?

Do not smoke while taking birth control pills, especially if you are older than 35 years of age.

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.
