Other than the obvious and most intended, which is to delay your period when it would be otherwise inconvenient to have one, taking Norethisterone can have a number of other benefits. Not only can it change when your period occurs, but it can also make your bleeding lighter, and your period less painful. The additional hormones can also help to reduce the number and severity of premenstrual symptoms such as having mood swings, bloating or stomach aches, headaches or changes to your skin or hair.
