Therapeutic patches typically last for a certain period, which can vary depending on the product. Some patches may provide relief for up to 12hours.
It is generally not recommended to use more than one patch at a time unless specifically instructed by a healthcare professional. Using multiple patches can lead to an overdose of the active ingredient, which can cause serious side effects. Always adhere to the dosage guidelines provided by the manufacturer.
The water resistance of therapeutic patches varies by product. Some patches are water-resistant and can be worn during swimming or showering, while others may need to be removed before getting wet. Always check the product's instructions for guidance on water exposure.
The effectiveness of a therapeutic patch can be determined by its adhesive strength and the presence of any visible signs of wear or discoloration. If the patch becomes loose, falls off, or appears damaged, it may no longer be effective and should be replaced according to the product's instructions.
