4. Be sure you have ready at all times:

Another kind of birth control (such as condoms or spermicide) to use as a back-up method in case you miss pills.

An extra, full pill pack.


You have a choice of which day to start taking your first pack of pills. Tri-VyLibra Lo is available in a blister pack which is preset for a Sunday Start. Day 1 Start stickers are also provided. Decide with your healthcare professional which is the best day for you. Pick a time of day that will be easy to remember.


Sunday Start:

Take the first white to off white “active” pill of the first pack on the Sunday after your period starts, even if you are still bleeding. If your period begins on Sunday, start the pack that same day.


Use another method of birth control (such as condoms or spermicide) as a back-up method if you have sex anytime from the Sunday you start your first pack until the next Sunday (7 days).


Day 1 Start:

Take the first white to off white "active" pill of the first pack during the first 24 hours of your period.


  1. Pick the day label strip that starts with the first day of your period (this is the day you start bleeding or spotting, even if it is almost midnight when the bleeding begins).
  2. Place this day label strip in the cycle tablet over the area that has the days of the week (starting with Sunday) imprinted in the plastic.

Day Label Sticker

Note: If the first day of your period is a Sunday, you can skip steps #1 and #2.


You will not need to use a back-up method of birth control, since you are starting the pill at the beginning of your period.
