How does this medication work? What will it do for me?
Desogestrel - ethinyl estradiol is an estrogen and progestin combination pill used for the prevention of pregnancy. It works by preventing ovulation (the release of an egg from an ovary) and causing changes in the mucus of the cervix that make it difficult for sperm to penetrate and for an egg to implant. It may also be taken to regulate the menstrual cycle.

How should I use this medication?
21-day pack: Take one tablet daily for 21 days, then do not take any pills for 7 days, and then begin the next pack.
28-day pack: Take one tablet daily for 21 days, then take one "reminder" pill daily for 7 days, and then begin the next pack.
Talk with your doctor about the best time to start your pills. The first day of your menstrual period (bleeding) is known as "Day 1." Your doctor may have you start your pills on the first Sunday after your period starts or on Day 1 of your period. The pills should be taken approximately the same time every day.
It may be advisable to use a second method of birth control (e.g., latex condoms and spermicidal foam or gel) for the first 7 days of the first cycle of pill use.
Many women have spotting or light bleeding or may feel sick to their stomach during the first 3 months taking the pill. If you do feel sick, do not stop taking the pill. The problem will usually go away. If it does not go away, check with your doctor or clinic.
If you have vomiting or diarrhea, or if you take some medications such as antibiotics, your pills may not work as well. If you start a new medication while you are taking birth control pills, check with your doctor or pharmacist to make sure that it will not reduce the effectiveness of the pills. Use a back-up method of birth control, such as latex condoms and spermicidal foam or gel, until you can check with your doctor or clinic.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important to take this medication exactly as prescribed by your doctor. If you miss pills at any time the risk of becoming pregnant increases. If you miss one pill, take it as soon as you remember, and take the next pill at the usual time. This means that you might take 2 pills in one day.
If you miss 2 pills in a row during the first 2 weeks of your cycle, take 2 pills the day you remember and 2 pills the next day, then take one pill a day until you finish the pack. Use a second method of birth control if you have sex in the 7 days after you miss the pills.
If you start your pills on Sunday, and you miss 2 pills in a row during the third week of your cycle or 3 or more pills in a row anytime in your cycle, keep taking one pill a day until Sunday. On Sunday, safely discard the rest of the pack and start a new pack that day.
If you start your pills on Day 1, and you miss 2 pills in a row during the third week of your cycle, or 3 or more pills at anytime during your cycle, safely dispose of the rest of the pill pack and start a new pack that same day. Use another method of birth control if you have sex in the 7 days after you miss the pills. You may not have a period this month. If you miss 2 periods in a row, call your doctor or clinic.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
