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. [See Contraindications (4), Warnings and Precautions (5.1), and FDA-Approved Patient Labeling.]

Starting TriNessa Lo after Childbirth

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.
    Figure
  • 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.
