Norethindrone tablets are usually taken for about 2 weeks in the treatment of functional uterine bleeding and are not usually taken for 6 months. Norethindrone tablets are a progestogen-like medication that can be used to treat functional uterine bleeding. For treatment, the medication is usually taken continuously for about 2 weeks. If the condition has not been relieved, it can be extended for a longer period of time. However, if the condition does not resolve for a long time, it is considered to be caused by other factors and the treatment needs to be adjusted. Therefore, it is not possible to take 6 consecutive months of kynurenine tablets to treat functional uterine bleeding. Taking norethindrone tablets will cause nausea and vomiting, dizziness and weakness, allergies and other adverse reactions, as well as serious liver and kidney disease and patients with breast lumps are prohibited, so the drug should be used reasonably under the guidance of the doctor. Patients with functional uterine bleeding must go to the hospital in time for examination and consultation, and choose the appropriate treatment plan under the guidance of the doctor.
