When you have a fever, the preferred location for a fever reduction patch is of course the forehead. Stick on the head is conducive to lowering the temperature of the head, which can make the patient feel more comfortable. Secondly, fever patches can also be applied to the body where the large arteries flow through, heat dissipation is also relatively fast. The common locations of the large arteries are both sides of the neck, the occipital area, the groin, the temples and the bilateral armpits. After applying the antipyretic patch, the body temperature should be monitored to observe the effect of cooling. It is important to note that it is best not to apply fever patches to the navel, chest, back of the ear, feet and vulva, as they can cause discomfort if applied. In addition, the skin surface should be cleaned of sweat and oil stains before use, otherwise the antipyretic paste will not stick.
