If your child has a fever of 38.1 degrees, he or she may not take fever-reducing medication, but use some physical cooling methods or effective treatment for the cause of the fever, which can relieve the fever of 38.1 degrees. For example, if you have a fever caused by a cold, you can use some antiviral drugs for anti-inflammatory purposes, such as Pudilan Anti-inflammatory Oral Liquid, Four Seasons Antiviral Combination, Ribavirin Granules, which are more effective. If the fever is caused by diarrhea, you can use Similac to stop the diarrhea, and if the diarrhea is caused by bacterial infection, you also need to use pediatric cefixime granules for anti-inflammatory treatment. If you have a history of febrile convulsions, even if the temperature of the fever is only 38.1 degrees and does not exceed 38.5 degrees, it is advisable to immediately give your child oral antipyretics to reduce the fever to avoid the occurrence of febrile convulsions, which are more dangerous and can be treated with oral ibuprofen suspension to reduce fever.
