Necon Dosage

Several types of Necon are available, but the dosing guidelines are the same for every woman. The standard Necon dosage is one pill taken once a day, at the same time every day. You can start the pills on the first day of your period or on the first Sunday after your period starts. If you miss any Necon doses, it significantly increases your risk of pregnancy.

Necon Dosage: An Introduction

As always, do not adjust your Necon® dosage unless your healthcare provider specifically instructs you to do so. Although the drug is effective when taken as directed, not taking it correctly greatly increases the risk of pregnancy.

Basic Necon Dosage Instructions

No matter what strength of Necon you take, start at the beginning of the pack, taking 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 let any days pass between packs, even if you are still having your period. The first 21 tablets contain the active ingredients. The last seven tablets do not contain any hormones. 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. If this happens, keep taking Necon as usual.
