Ortho Evra Dosage: An Introduction
There is only one standard dose of Ortho Evra®
(norelgestromin/ethinyl estradiol). As always, do not adjust your Ortho Evra dose unless your healthcare provider specifically instructs you to do so.
Ortho Evra Dosing for Birth Control
One Ortho Evra patch
should be applied every seven days for three weeks in a row (don't forget to take the old patch off each time). After the third week, the last patch is removed for a seven-day break without any patches. You will usually start your period during this week. After seven days, you should start a new Ortho Evra cycle, even if you are still having your period.
When you take Ortho Evra for the first time, you can start Ortho Evra either on the first day of your period or on the first Sunday after your period starts. If you start Ortho Evra on the first day of your period (a "day 1 start"), you do not need to use 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). If you switch from another type of birth control pill
, start taking Ortho Evra on the day you would normally start a new pack of birth control pills (no backup necessary).
