How should I take Aygestin?

To best treat your condition, Aygestin should be used exactly as your doctor has prescribed it for you. Do not use more of the medication than recommended. Do not take Aygestin for longer than your doctor has prescribed.
Take the medication at the same time each dose day. Taking a pill late or missing a pill can increase your chances of having breakthrough bleeding or getting pregnant.
For birth control, start a new pack of pills the day after your last pack is finished. There is no break between packs.
If you vomit soon after taking Aygestin, use a backup method of birth control (such as a condom and/ or spermicide) for 48 hours.
You may have some light bleeding or spotting between periods. Continue taking Aygestin even if this occurs.
If your menstrual period is late you may be pregnant. If it has been more than 45 says since the start of your last period, call your doctor or use a home pregnancy test.
You will need to have yearly physical exams and Pap smears while you are using Aygestin. Examine your breasts at home every month to check for lumps. It is important that you not miss any scheduled visits to your doctor.
After you stop using Aygestin, you may start bleeding within a few days.
Store Aygestin at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Then take the next dose at your regularly scheduled time. Do not take extra medicine to make up the missed dose.
If you were more than 3 hours late in taking your dose, use a backup method of birth control (such as a condom and/ or spermicide). Keep using the backup method for at least 48 hours to ensure protection from pregnancy.
If you are not sure what to do about a missed dose, keep taking Aygestin and use a backup method of birth control until you can talk to your doctor.
