STD Home > Zeosa Dosage
It is important to take a dose of Zeosa every day and at the same time each day. Missing pills increases the risk of unintentional pregnancy. You can start taking this oral contraceptive either on the first day of your period or on the first Sunday after your period starts. If you miss a dose, backup contraception is often necessary for a week.
An Introduction to Dosing With ZeosaThere is only one standard dose of Zeosa™ (norethindrone/ethinyl estradiol). As always, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Zeosa Dosage for Birth ControlStarting at the beginning of the pack, take one tablet at the same time each day. Each pack will last four weeks (28 days). After you finish one pack, immediately start a new one. Do not let any days pass between packs (this may take a little planning, as you will need a new pack on hand).
The first 21 tablets contain the active ingredients. The last seven tablets do not contain any hormones, although they contain a little iron to help prevent anemia. With these last seven tablets, your body gets a little break from the hormones, allowing you to have a period.
When you take Zeosa for the first time, you can start it either on the first day of your period (within the first 24 hours after bleeding starts) or on the first Sunday after your period starts, even if you are still bleeding. If you start Zeosa 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).
