Can fever-reducing patches be stored in the refrigerator?

Generally, fever-reducing patches can be stored in the refrigerator's chiller compartment. Since these patches are inherently cool, refrigeration helps enhance their fever-relieving effect. However, they should not be placed in the freezer compartment. Freezing makes the patch hard and less flexible, reducing its ability to adhere properly to the skin and thus diminishing its effectiveness. Detailed explanations are as follows:

Fever-reducing patches are common physical cooling products. Their primary mechanism involves using water within a high-molecular-weight gel to evaporate and draw heat away from the body. They can also help relieve symptoms such as headaches caused by colds. When body temperature is below 38.5°C, applying these patches can achieve effective cooling. Generally, fever-reducing patches should be stored away from light and in a cool place; however, storing them in the refrigerator's chiller compartment is even better. When needed, simply remove the patch from the refrigerator and use it immediately. It is recommended not to store them for excessively long periods, as prolonged storage may reduce their effectiveness.

Typically, fever-reducing patches are applied to areas such as the forehead, neck (over major arteries), armpits, and groin. Multiple patches can be used simultaneously, with each application lasting 6–8 hours. If body temperature decreases during this period, the patch can be removed early. If symptoms persist after 8 hours, a new patch may be applied.

When applying a fever-reducing patch, check whether the application site shows signs of redness, swelling, pain, or itching. If any of these symptoms occur, remove the patch promptly and take appropriate measures accordingly.
