Antibiotic drugs can be used, and commonly used antibiotic drugs include penicillin, cephalosporin and macrolides. When the child has a fever, you can drink more water, pay attention to rest, supplement vitamin C to prevent cross-infection. At the same time, you need to test your baby’s temperature, if the temperature rises to 38.5 ℃, you should use antipyretic drugs to reduce fever treatment. If the temperature does not reach 38.5 ℃, physical cooling can be used.
