 Detailed Ortho Tri-Cyclen dosage information
What happens if I miss a dose?
Follow the instructions provided with your medicine. Missing an Ortho Tri-Cyclen pill increases your risk of becoming pregnant.
If you miss 1 active pill, take 2 pills on the day you remember. Then take 1 pill per day for the rest of the pack.
If you miss 2 active pills in a row in Week 1 or 2, take 2 pills per day for 2 days in a row. Then take 1 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 2 active pills in a row in Week 3, throw out the pack and start a new pack the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack that day.
