For mild dysmenorrhea, you can drink hot water or brown sugar water, use a hot water bag for localized hot compresses on the abdomen, including baby warmers, and get enough sleep to relieve it. If the pain is unbearable, you can take oral medication, such as ibuprofen extended-release tablets or ibuprofen extended-release capsules. There are some people who are resistant when they hear about the drug, such a drug is able to relieve the pain, the duration will be about 12 hours, can be taken orally on the 2nd-3rd day of menstruation, but not every day, the drug metabolism is very fast, as long as about 4 hours will be completely metabolized, will not affect the health of the body.
