Baby has fever for two days if the fever does not go down: first of all, you need to use anti-fever medication. It is recommended to measure the body temperature first. If the body temperature is not too high below 38.5 degrees, you can use pediatric antelope horn granules, pediatric black beetle clearing granules, or pediatric cold and fever clearing granules for fever reduction. If the body temperature is higher than 38.5 degrees, it is recommended to use ibuprofen suspension or acetaminophen granules to reduce fever. If the above treatment is still not effective, you need to promptly consult a doctor to find out the cause of the fever for targeted treatment, otherwise the child’s fever may continue to worsen, it is best to check the blood routine, C-reactive protein. If there are elevated white blood cells and elevated C-reactive protein in the blood routine, most of the fever is caused by bacterial infection, and can be treated with antibiotics, such as pediatric cefixime granules or pediatric cefadroxil granules, the effect is good.
