Norethindrone can help with endometriosis when taken at a higher dose.[popover id=ref1] This isn’t the same as using norethindrone for birth control. To treat endometriosis, 5mg of norethindrone is taken daily for six to nine months.
A higher dose of norethindrone can also be used to delay your period, or to help your cycle get back on track if you’ve stopped menstruating. Because a normal birth-control dose of norethindrone is only 0.35mg, you’ll want to talk to your doctor about a norethindrone prescription for period delay or restart.
