Oral Contraception

To achieve maximum contraceptive effectiveness, ORTHO TRI-CYCLEN® Lo Tablets must be taken exactly as directed and at intervals not exceeding 24 hours. The possibility of ovulation and conception prior to initiation of medication should be considered. ORTHO TRI-CYCLEN® Lo is available with the DIALPAK® Tablet Dispenser which is preset for a Sunday Start. Day 1 Start is also provided.

Sunday Start

When taking ORTHO TRI-CYCLEN® Lo the first white "active" tablet should be taken on the first Sunday after menstruation begins. If the menstrual period begins on Sunday, the first white "active" tablet should be taken that day. Take one white, light blue or dark blue "active" tablet daily for 21 days followed by one dark green "reminder" tablet daily for 7 days. After 28 tablets have been taken, a new course is started the next day (Sunday). For the first cycle of a Sunday Start regimen, another method of contraception should be used until after the first 7 consecutive days of administration.

If the patient misses one (1) white, light blue, or dark blue "active" tablet in Weeks 1, 2, or 3, the tablet should be taken as soon as she remembers. If the patient misses two (2) white or light blue "active" tablets in Week 1 or Week 2, the patient should take two (2) "active" tablets the day she remembers and two (2) "active" tablets the next day; and then continue taking one (1) tablet a day until she finishes the pack. The patient should be instructed to use a back-up method of birth control if she has sex in the seven (7) days after missing pills. If the patient misses two (2) dark blue "active" tablets in the third week or misses three (3) or more "active" tablets in a row, the patient should continue taking one tablet every day until Sunday. On Sunday the patient should throw out the rest of the pack and start a new pack that same day. The patient should be instructed to use a back-up method of birth control if she has sex in the seven (7) days after missing pills.
