Because Backup Plan Onestep (Levonorgestrel) is often associated with nausea, your doctor may also want you to take medication to prevent nausea at the same time as taking these pills. If you vomit within 2 hours of taking the tablet, you should contact your health care provider as you may need to take another dose. Backup Plan Onestep (Levonorgestrel) can be used at any time during the menstrual cycle. It can be taken with or without food. Taking it with food may help reduce the nausea.

Most women have their expected menstrual period within 7 days of their normal time after using this medication. If you don't have your menstrual period within 7 days of when it is expected, you should have a pregnancy test done.
