Ibuprofen granules are commonly used clinically as antipyretic and analgesic drugs. For persistent fever as well as pain, it is recommended to take them once every 4-6 hours, but the number of doses should not exceed 4 times in 24 hours. Ibuprofen granules are mostly used for the symptomatic treatment of fever caused by upper respiratory tract infections and other diseases, as well as mild to moderate pain, such as toothache, headache and dysmenorrhea. Usually when the body temperature exceeds 38.5°C, you can take ibuprofen granules orally to effectively reduce fever for 6-8 hours. If the body temperature rises again, you can continue to take the drug to reduce fever, but not more than 4 times in 24 hours at most to avoid side effects. It is usually used to reduce fever for no more than 3 days and can be stopped when the body temperature no longer rises or the pain is relieved. During the period of medication, pay attention to drink more water to replenish the water lost by the body due to fever, eat fresh vegetables and fruits appropriately, and pay attention to more rest to facilitate the recovery of the disease.
