Tri-Linyah Dosage

Starting Tri-Linyah 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 or on the first Sunday after your period starts. It is thought that starting on Sunday may decrease the chance that you will have your periods on the weekends, although this is not always the case. Make sure to follow your healthcare provider's instructions concerning when to start Tri-Linyah.
 
If you start Tri-Linyah on the first day of your period (a "day 1 start"), you do not need to use any backup contraception. If you choose a Sunday start, you will 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).
 
If your healthcare provider recommends it, you may also start Tri-Linyah in the middle of your cycle; however, this is not one of the officially recommended starting methods. Follow your healthcare provider's advice about how long backup birth control is necessary in this case.
 

What to Do If You Miss a Tri-Linyah Dose

It is important that you take Tri-Linyah 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 have missed, whether you are a day 1 starter or a Sunday starter, and when in the cycle the pills were missed. If you are unsure about what to do, please use a backup method of birth control until you can speak with your healthcare provider.
 
Some general instructions for missed Tri-Linyah doses include the following:
 
  • 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. You do not need to use a backup method of contraception, as you will be adequately protected against pregnancy.
 
  • If you miss two pills in a row during the first or second weeks 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, such as condoms, 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. These instructions include the following:
 
    • 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, such as condoms, for a week. You may not have your period as usual this month, as you have skipped the pills that do not contain any hormones.
 
  • If you miss any of the last seven pills (the fourth week of the pack), throw away these pills 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.
