Portia Dosing

To ensure the effectiveness of Portia, dosing guidelines must be followed carefully. You should take one tablet at the same time each day. After finishing one pack, start a new one the next day. When starting the contraceptive for the first time, you can take your Portia dose either on the first day of your period or the first Sunday after your period starts.

Portia Dosing: An Introduction

Portia® (levonorgestrel/ethinyl estradiol) is a generic version of Nordette®. There is only one standard dose of Portia. As always, do not adjust your Portia dose unless your healthcare provider specifically instructs you to do so. Even though Portia is very effective when taking as directed, not taking Portia correctly increases the risk of unintentional pregnancy.

Portia Dosing for Birth Control

Starting at the beginning of the pack, take one tablet daily. It should be taken at the same time every day. One 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 of each pack 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. Sometimes, you may have breakthrough bleeding or spotting between periods. This is especially common for the first few months you take Portia. When this happens, keep taking Portia as usual.
