Ortho-Novum Dosage

Several different strengths are available; however, Ortho-Novum dosing guidelines are the same for every woman. You must take one tablet every day, at the same time each day. As soon as you finish one pack, start a new one the next day. It's important to know what to do if you miss your Ortho-Novum dosage, as missing doses can significantly increase your risk of pregnancy.
