Medical fever-reducing patches utilize the physical properties of special materials to lower body temperature. This is a commonly used and safe method of physical cooling in clinical practice. It is recommended to apply medical fever-reducing patches to areas with rich subcutaneous blood vessels and blood flow, such as the forehead, sides of the neck, armpits, and groin, to better lower blood temperature and thus reduce body temperature.
Medical fever-reducing patches can be used when body temperature is elevated and can be used simultaneously with other fever-reducing methods, including various antipyretic medications. Medical fever-reducing patches are safe for use by the elderly, people with impaired liver or kidney function, and infants. Each patch typically lasts for 2-3 hours.
