- This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
- The schedule you follow for taking this medicine is different from the schedule for most other birth control pills.
- Unless your doctor tells you to use a different schedule, start taking this medicine on the first Sunday after your menstrual period starts. If your period starts on a Sunday, start taking this medicine on that day. Then continue taking one pill each day in the order they appear in the package.
- It is best to take your pill at the same time every day. Birth control pills work best when there is no more than 24 hours between doses. It is very important that you take this medicine on schedule every day.
If a dose is missed:
- If you miss one active pill, take it as soon as you can. Then take your next pill at the regular time. This means you may take two pills in one day.

- If you miss three or more active pills, do not take the pills you missed. Go back to taking one pill every day, starting with the pill for the day you remember. For example, you may forget or miss taking your pills on Monday, Tuesday, and Wednesday. If this happens, take your Thursday pill (do not take the three you missed) and continue with your regular schedule.
