What is Seasonique?
Seasonique is a birth control pill that contains a combination of ethinyl estradiol and levonorgestrel. Ethinyl estradiol and levonorgestrel are female hormones that prevent ovulation (the release of an egg from an ovary).
Seasonique 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.
Seasonique is used as contraception to prevent pregnancy.
Do not use Seasonique if you are pregnant or if you have recently had a baby.
You should not take Seasonique if you have any of the following conditions: uncontrolled high blood pressure, heart disease, a blood-clotting disorder, circulation problems, diabetic problems with your eyes or kidneys, unusual vaginal bleeding, liver disease or liver cancer, severe migraine headaches, if you smoke and are over 35, or if you have ever had breast or uterine cancer, jaundice caused by birth control pills, a heart attack, a stroke, or a blood clot.
Taking Seasonique can increase your risk of blood clots, stroke, or heart attack, especially if you have certain other conditions, or if you are overweight.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. You should not take Seasonique if you smoke and are over 35 years old.
Missing a pill increases your risk of becoming pregnant. Carefully follow the "missed dose" instructions if you forget to take your Seasonique tablets.
Some drugs can make Seasonique less effective in preventing pregnancy, including antibiotics, hepatitis C medications, HIV/AIDS medications, seizure medications, or barbiturate sedatives. Tell your doctor about all other medications you use.
Before taking this medicine
Taking Seasonique 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 Seasonique. Your risk is also high when you restart Seasonique 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 Seasonique if you smoke and are over 35 years old.
Do not use if you are pregnant. Stop using Seasonique 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 Seasonique.
You should not take Seasonique if you have:
untreated or uncontrolled high blood pressure;
heart disease (coronary artery disease, uncontrolled heart valve disorder, history of heart attack, stroke, or blood clot);
a blood-clotting disorder or circulation problems;
problems with your eyes, kidneys or circulation caused by diabetes;
a history of hormone-related cancer such as breast or uterine cancer;
unusual vaginal bleeding that has not been checked by a doctor;
liver disease or liver cancer;
severe migraine headaches (with aura, numbness, weakness, or vision changes), especially if you are older than 35;
a history of jaundice caused by pregnancy or birth control pills; or
if you smoke and are over 35 years old.
To make sure Seasonique are safe for you, tell your doctor if you have ever had:
heart disease, high blood pressure, or if you are prone to having blood clots;
high cholesterol or triglycerides, or if you are overweight;
diabetes, underactive thyroid, gallbladder disease;
a seizure or migraine headache;
irregular menstrual cycles; or
fibrocystic breast disease, lumps, nodules, or an abnormal mammogram.
The hormones in Seasonique can pass into breast milk and may harm a nursing baby. This medication may also slow breast milk production. Do not use if you are breast feeding a baby.
How should I take Seasonique?
Take Seasonique exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
You will 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 this medication. 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.
You will not have a menstrual period every month while you are taking an extended-cycle birth control pill. Instead, your period should occur every 12 weeks.
The 91-day birth control pack contains three trays with cards that hold 84 "active" pills and seven "reminder" pills. You must use the pills in a certain order to keep you on a regular cycle. Trays 1 and 2 each hold 28 pills. Tray 3 holds 35 pills, including the 7 reminder pills. Your period should 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.
Use a back-up birth control if you are sick with severe vomiting or diarrhea.
If you need surgery or medical tests 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 Seasonique.
While taking Seasonique, you will need to visit your doctor regularly.
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, 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 three "active" pills in a row, do not take the missed pills. Continue taking 1 pill per day on schedule according to the pill package and leave the missed pills in the package. You may have some bleeding or spotting if you miss three pills in a row. Use back-up birth control for at least the next 7 days.
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. If your period does not start while you are taking the reminder pills, call your doctor because you might be pregnant.
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 vaginal bleeding.
What should I avoid while taking Seasonique?
Do not smoke while taking Seasonique, especially if you are older than 35 years of age.
Seasonique 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.
