Is a body temperature of 38.1°C considered a high fever in adults?

A body temperature of 38.1°C in adults is not considered a high fever but falls within the low-grade fever range; a true high fever is generally defined as ≥38.5°C. If the patient’s general condition remains stable, physical cooling methods (e.g., tepid sponging, adequate rest) may be tried first. However, if fever persists, timely administration of antipyretic medication is recommended, along with increased fluid intake. Once an adult’s temperature rises above 38°C, fever is confirmed, and pharmacologic intervention may be initiated. Commonly used antipyretics include Ketorolac (brand name: Kuai Ke), Jiuzhou Cold & Flu Granules (brand name: Sanjiu Ganmaoling), and cephalosporin antibiotics—though it should be noted that cephalosporins are antibiotics, not antipyretics, and should only be used if a bacterial infection is suspected or confirmed.
