How to Take Estarylla 28 Day

Each pack contains 28 tablets taken in order:

1. Days 1–21: Take one active (blue) tablet daily. Each contains Norgestimate 0.25 mg and Ethinyl Estradiol 0.035 mg.
2. Days 22–28: Take one inert (green) tablet daily. These contain no active hormones — they keep you in the habit of taking a daily pill. Your period will usually start during this week.
3. Day 29: Start a new pack immediately. Don't skip any days between packs.

Important Dosing Tips

• Take it at the same time every day. Consistency improves effectiveness and helps you remember.
• Starting options: You can start on Day 1 of your period (no backup needed) or the first Sunday after your period begins (use backup contraception like condoms for the first 7 days).
• If you miss one pill: Take it as soon as you remember, even if that means taking two pills in one day. No backup method needed.
• If you miss two or more pills: Follow the instructions in your package insert or call your doctor. You may need backup contraception.
• If you vomit within 4 hours of taking a pill: Treat it as a missed pill.
