Lo/Ovral Dosage

Starting Lo/Ovral for the First Time

When you take a birth control pill for the first time, you can usually choose to start either on the first day of your period (a day 1 start) or on the first Sunday after your period starts (a Sunday start). Starting on a Sunday may decrease the chance that you will have your periods on the weekends, although this is not always the case. Be aware that if you choose a day 1 start, the labeled days on the pack may not be correct (they are labeled for a Sunday start only). Be sure to follow your healthcare provider's instructions concerning when to start Lo/Ovral.
If you start Lo/Ovral on the first day of your period, you do not need any backup contraception. If you choose a Sunday start, you need to use a backup method of contraception, such as condoms, for the first week. If the first day of your period happens to be on a Sunday, treat this as a day 1 start (no backup needed).
Check with your healthcare provider for more specific instructions if you are starting Lo/Ovral after a birth, miscarriage, or abortion, or if you are switching from a different type of hormonal birth control (such as a different birth control pill, patch, ring, or injection).

What If I Miss a Lo/Ovral Dose?

It is important that you take Lo/Ovral every day and at the same time each day, even if you do not have sex very often. Missing pills increases the risk of pregnancy. What you should do if you miss pills depends on how many pills you missed, whether you are a day 1 starter or a Sunday starter, and when in the cycle the pills were missed. General instructions for missed pills include:
  • If you miss one of the first 21 pills, take the missed pill as soon as you remember and take the next pill at your regular time, even if this means taking two pills at once. Be sure to use a backup method of birth control, such as condoms, for seven days after you miss a pill.
  • If you miss two pills in a row during the first or second week of the pack, take two pills on the day you remember and two pills the next day. This should get you back on your regular schedule. You must use a backup method of contraception if you have sex in the seven days after you restart the pills.
  • If you miss two pills in a row during the third week of the pack (or three or more pills in a row during weeks one through three), your instructions will vary, depending on whether you are a day 1 starter or a Sunday starter. If you are a day 1 starter, throw out the rest of the pack and start a new pack right away. If you are a Sunday starter, take one pill every day until Sunday. On Sunday, throw out the pack and start a new one (this keeps you on track as a Sunday starter). Either way, you need to use a backup method of contraception for a week. You may not have your period as usual this month, since you skipped the pills with no active ingredients.
  • If you miss any of the last seven pills (the fourth week of the pack), throw away the pills you missed and continue as usual. Missing these pills will not increase your risk of pregnancy, as long as you start your next pack on time. No backup contraception is necessary.
