Menstrual pain medication can be harmful if taken in excess. Some western medicines such as ibuprofen and ketoprofen can reduce prostaglandin production and are very effective in relieving pain. However, regular use can cause gastrointestinal damage, such as peptic ulcers, and even cause a tendency to bleed in the digestive system. Some women choose Chinese herbs to treat dysmenorrhea, some of which are nephrotoxic and may cause kidney damage when taken for a long time. If you have symptoms of dysmenorrhea, you should go to the hospital for pelvic ultrasound, internal gynecological examination, and the corresponding laboratory tests, etc., and treat them according to the test results. Medications can only relieve the symptoms of pain, they do not treat the primary disease and cannot solve the problem of dysmenorrhea at the root. Whether it is western medicine or Chinese medicine, taking too much of it can cause damage to the liver, so be sure to take the medication as prescribed by your doctor and go to the hospital for regular medical checkups.
