A four-year-old child has a fever of 39 degrees. If the child is in good spirits, eats well and has normal bowel movements, he should drink more water, take rest, take vitamin C supplements and try to avoid going to crowded places to prevent cross infection. You can swab your child’s forehead, armpits and groin with warm water to help reduce fever. You can take oral ibuprofen suspension, or acetaminophen suspension and other antipyretic and analgesic drugs, which can play a fast role in reducing fever. If the fever is caused by cold, you can take pediatric aminophenol xanthamine granules orally, which can treat and relieve various symptoms caused by cold, such as fever, headache, nasal congestion, runny nose, sneezing and sore throat. You can also take oral Chinese medicine, such as Blue Scutellaria Oral Liquid, Qingkai Ling Granules, Antelope Horns Granules, etc., to clear the heat and detoxify the toxins.
