How to Use This Medicine

Tablet

  • Your doctor will tell you how much of this medicine to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
  • This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
  • Start taking this medicine on the first Sunday after your menstrual period. 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.
  • 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 two active pills in a row, take two pills as soon as you can. Then take two pills on the next day. Then go back to your regular schedule of taking one pill every day. Use another kind of birth control until you have been taking active pills for seven days in a row.
  • 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.
  • You could have light bleeding or spotting any time you do not take a pill on schedule. The more pills you miss, the more likely you are to have bleeding.
  • If you miss any inactive pills, throw away the missed pills and go back to your regular schedule.
