A cold and fever is an inflammatory response of the body’s immune system to protect itself. Occasional fever can improve resistance to viruses and bacteria and is not necessarily a bad phenomenon. When you have a cold and fever, you can take anti-cold medicines such as cold and flu granules, aminophenol pseudo-masalamine tablets, and MeiYi pseudo-masaline capsules orally, which can treat and relieve various symptoms caused by common cold and influenza, such as fever, headache, nasal congestion, runny nose, sneezing and sore throat. It can also be treated by oral Chinese medicine, such as Pu Di Lan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid, Qing Kai Ling Granules, Ban Lan Gen Granules, Antelope Granules, etc. to clear heat and detoxify toxins. If the fever is caused by a wind-cold cold, it can be treated with Jing Fang Wei Po Poison San plus or minus, which has the efficacy of pungent warming and relieving the symptoms. For fever over 38.5 degrees, you can take ibuprofen suspension orally, which can quickly reduce fever.
