Patients with chickenpox who develop fever can be given medication to reduce fever, physical cooling and other methods to reduce fever, and those who are severe or have complications need antiviral treatment. Chickenpox is caused by herpes virus infection, which is self-limiting, so it is usually treated symptomatically. If the chickenpox is caused by low fever symptoms, you can use physical cooling mainly, use warm water for appropriate baths, ice packs to cool down the temperature and other treatments. If the body temperature is high, you can use antipyretic and analgesic drugs, such as ibuprofen, acetaminophen, etc., or also can use dexamethasone and other glucocorticoid drugs. If the patient’s symptoms are severe or accompanied by complications, antiviral medications such as acyclovir may be added early on. After the virus is under control, the patient’s fever symptoms will also improve. Chickenpox is contagious, and it is recommended to visit a hospital and use medication under a doctor’s supervision to deal with it.
