What happens if I miss a dose (Seasonale)?
Missing a pill increases your risk of becoming pregnant.
If you miss one "active" pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.
If you miss two "active" pills in a row, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days following the missed pills.
If you miss three "active" pills in a row, do not take the missed pills. Continue taking 1 pill per day on schedule according to the pill package and leave the missed pills in the package. You may have some bleeding or spotting if you miss three pills in a row. Use back-up birth control for at least the next 7 days.
If you miss any reminder pills, throw them away and keep taking one pill per day until the pack is empty. You do not need back-up birth control if you miss a reminder pill. If your period does not start while you are taking the reminder pills, call your doctor because you might be pregnant.
What happens if I overdose (Seasonale)?
Seek emergency medical attention if you think you have used too much of this medicine. Overdose symptoms may include nausea, vomiting, and vaginal bleeding.
