To decrease the risk of pregnancy while using Tri-Sprintec, dosing guidelines for the oral contraceptive must be followed carefully. You should take one tablet at the same time each day, making sure to take the pills in order. After finishing one pack, start a new one immediately the next day. It is important to take your Tri-Sprintec dose at the same time each day.

Tri-Sprintec Dosing: An Introduction

Tri-Sprintec® (norgestimate/ethinyl estradiol) is a generic version of Ortho Tri-Cyclen®. There is only one standard dose of Tri-Sprintec. As always, do not adjust your dose, unless your healthcare provider specifically instructs you to do so. Not taking Tri-Sprintec correctly increases the risk of unintentional pregnancy.

Tri-Sprintec Dosing: Starting the Drug

When you take Tri-Sprintec 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 Tri-Sprintec 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.
