Thank you for your question. For the treatment of endometriosis norethisterone, a synthetic analog of the female hormone progesterone can be administered to treat symptoms associated with this disease. This medication works by delaying the menstrual period, thereby suppressing the pain, discomfort, or bleeding caused by endometrial tissue which is outside the uterus. The dosage of this medication depends on your personal symptom profile, natural progesterone levels, body weight, and other associated factors which are considered by your doctor. At first, the lowest dosage is usually given to see if will adequately help. If this does not work, then this medication will incrementally increased so that it functions at a therapeutic level in treating symptoms.
