How to Start TriNessa Lo

TriNessa Lo is dispensed in a VERIDATE Tablet Dispenser. TriNessa Lo may be started using either a Day 1 start or a Sunday start (see Table 1). For the first cycle of a Sunday Start regimen, an additional method of contraception should be used until after the first 7 consecutive days of administration.

How to Take TriNessa Lo

Table 1: Instructions for Administration of TriNessa Lo
Starting COCs in women not currently using hormonal contraception (Day 1 Start or Sunday Start) Important: Consider the possibility of ovulation and conception prior to initiation of this product. Tablet Color: TriNessa Lo active tablets are white (Day 1 to Day 7), light blue (Day 8 to Day 14) and dark blue (Day 15 to Day 21). TriNessa Lo inactive tablets are dark green (Day 22 to Day 28).

Begin each subsequent pack on the same day of the week as the first cycle pack (i.e., on the day after taking the last inactive tablet)
	Sunday Start: Take first active tablet without regard to meals on the first Sunday after the onset of menses. Due to the potential risk of becoming pregnant, use additional non-hormonal contraception (such as condoms and spermicide) for the first seven days of the patient's first cycle pack of TriNessa Lo. Take subsequent active tablets once daily at the same time each day for a total of 21 days. Take one dark green inactive tablet daily for the following 7 days and at the same time of day that active tablets were taken. Begin each subsequent pack on the same day of the week as the first cycle pack (i.e., on the Sunday after taking the last inactive tablet) and additional non-hormonal contraceptive is not needed.

Starting TriNessa Lo after Abortion or Miscarriage

First-trimester

After a first-trimester abortion or miscarriage, TriNessa Lo may be started immediately. An additional method of contraception is not needed if TriNessa Lo is started immediately.
If TriNessa Lo is not started within 5 days after termination of the pregnancy, the patient should use additional non-hormonal contraception (such as condoms and spermicide) for the first seven days of her first cycle pack of TriNessa Lo.

Second-trimester

Do not start until 4 weeks after a second-trimester abortion or miscarriage, due to the increased risk of thromboembolic disease. Start TriNessa Lo, following the instructions in Table 1 for Day 1 or Sunday start, as desired. If using Sunday start, use additional non-hormonal contraception (such as condoms and spermicide) for the first seven days of the patient's first cycle pack of TriNessa Lo.

Starting TriNessa Lo after Childbirth

Do not start until 4 weeks after delivery, due to the increased risk of thromboembolic disease. Start contraceptive therapy with TriNessa Lo following the instructions in Table 1 for women not currently using hormonal contraception.
TriNessa Lo is not recommended for use in lactating women.
If the woman has not yet had a period postpartum, consider the possibility of ovulation and conception occurring prior to use of TriNessa Lo.

VERIDATE® Tablet Dispenser

Place the refill in the VERIDATE Tablet Dispenser so that the V notch in the refill is at the top of the dispenser. Press the refill down so that it fits firmly under all the nibs (see illustration below).
If the patient starts pill-taking on Sunday, the first active pill should be taken on the first Sunday after the patient's menstrual period begins. Remove the first active pill at the top of the dispenser (Sunday) by pressing the pill through the hole in the bottom of the dispenser.
If the patient will start pill-taking on a day other than Sunday, a calendar label has been provided and should be placed over the calendar in the center of the VERIDATE. To place the label correctly, identify the correct starting day, locate that day printed in blue on the label, and line that day up with the first white pill directly under the V notch at the top of the dispenser. Remove the label from the backing. Press the center of the label down onto the center of the printed calendar. Remove that white pill by pressing the pill through the hole in the bottom of the dispenser.
After all the dark green pills have been taken, insert a new refill into the VERIDATE. The patient should take the first pill on the next day, even if the patient's period is not over yet.

To Insert New Refill:

Lift the empty refill out of the VERIDATE Tablet Dispenser.
Insert the new refill so that the V notch in the refill is at the top of the dispenser. Press the refill down so that it fits firmly under the nibs.

If two active tablets are missed in Week 1 or Week 2	Take the two missed tablets as soon as possible and the next two active tablets the next day. Continue taking one tablet a day until the pack is finished. Additional non-hormonal contraception (such as condoms and spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets.
If two active tablets are missed in the third week or three or more active tablets are missed in a row in Weeks 1, 2, or 3	Day 1 start: Throw out the rest of the pack and start a new pack that same day.

Advice in Case of Gastrointestinal Disturbances

In case of severe vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken. If vomiting or diarrhea occurs within 3 to 4 hours after taking an active tablet, handle this as a missed tablet.
