Introduction
Medical cooling patches are generally suitable for use when body temperature is within 38.5°C, typically between 37.3°C and 38.5°C, providing a physical cooling effect. However, if body temperature exceeds 38.5°C, medical cooling patches may not effectively reduce fever. In such cases, it is recommended to promptly follow medical advice and take antipyretic medications to lower body temperature and relieve symptoms.
Medical fever-reducing patches are generally used when body temperature is below 38.5°C.
Medical fever-reducing patches are products composed of physical cooling materials and various fixing components, designed for physical fever reduction and localized cooling on the body surface. When used for fever management, they are typically suitable for temperatures up to 38.5°C—specifically in the range of 37.3°C to 38.5°C—and can provide a physical cooling effect. However, if a patient's body temperature exceeds 38.5°C, medical fever-reducing patches may not effectively lower body temperature. In such cases, it is recommended that patients promptly take antipyretic medications under a doctor’s guidance to reduce fever and relieve symptoms. Commonly used medications include acetaminophen tablets and ibuprofen sustained-release capsules.
When using medical fever-reducing patches, patients can apply them to areas such as the groin or over the carotid arteries on either side of the neck. These sites are chosen because they have rich blood supply, which helps achieve more effective whole-body heat dissipation. The effective duration of a medical fever-reducing patch is approximately 6 to 8 hours. If the patient's temperature remains elevated after 6–8 hours, reapplication may be considered.
