Ortho Tri-Cyclen Dosage

There is only one standard Ortho Tri-Cyclen dosage. Starting at the beginning of the pack (which contains 28 pills), take one tablet at the same time each day. After you finish one pack, immediately start a new one the next day. You must take the tablets in order. To help ensure the effectiveness of Ortho Tri-Cyclen, dosing guidelines must be followed carefully.

Ortho Tri-Cyclen Dosage: An Introduction

There is only one standard dose of Ortho Tri-Cyclen® (norgestimate/ethinyl estradiol). As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so. Not taking Ortho Tri-Cyclen correctly increases the risk of unintentional pregnancy.
(Ortho Tri-Cyclen is equivalent to Norgestimate and Ethinyl Estradiol, Tri-Estarylla™, Tri-Linyah™, Tri-Sprintec®, TriNessa®, and Tri-Previfem® birth control pills. The information in this article also applies to each of these medications.)

Ortho Tri-Cyclen Dosing

When you take Ortho Tri-Cyclen for the first time, you can start it either on the first day of your period or on the first Sunday after your period starts. Starting on Sunday may decrease the chance that you will have your periods on the weekends, although this is not always the case. If you start Ortho Tri-Cyclen on the first day of your period (a "day 1 start"), you do not need any backup contraception. If you choose a Sunday start, you 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).
Starting at the beginning of the pack, take one tablet daily at the same time each day. Each pack will last for 28 days (four weeks). After you finish one pack, immediately start a new one the next day. Do not wait any days between packs (this may take a little planning, since you will need a new pack on hand). The first 21 tablets contain the active ingredients. The last seven tablets contain no active ingredients. During this last week, your body gets a little break from the hormones, allowing you to have a period.
