Drugs Home > Errin Dosing
It is important to take your Errin dose at the same time each day. Take one tablet daily, starting at the beginning of the pack. Do not wait any days between packs; after finishing one pack, immediately start a new one the next day. You must follow Errin dosing guidelines carefully, as taking the pill just several hours late can increase your risk of pregnancy.
Errin® (norethindrone) is a generic version of Ortho Micronor®. There is only one standard dose of Errin. As always, do not adjust your Errin dose unless your healthcare provider specifically instructs you to do so. Although Errin is very effective when taken as directed, not taking Errin correctly increases the risk of unintentional pregnancy.
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). Unlike other types of birth control pills, every tablet in the pack contains hormones (there are no inactive or placebo pills and no breaks between pills).
It is best to start Errin on the first day of your period. You may start it on a different day, but you need to use a backup method of birth control (such as condoms) for 48 hours after starting Errin in this situation. Make sure to pick a time that works well for you, since you will have to take the pills at the exact same time each day. If you had a miscarriage or abortion, you can start Errin the next day.
If you are exclusively breastfeeding (if you are not supplementing with formula or food), you can start Errin six weeks after delivery. If you are not exclusively breastfeeding (if you are breastfeeding and using formula or food), you should start Errin three weeks after delivery.
Check with your healthcare provider about how and when to start Errin when switching from a different form of birth control (including other kinds of birth control pills).
