We understand how frustrating it is when your patch does not stick. Lack of adhesion may be attributed to hot weather, patient skin type, or activity. Please be sure you have applied the patch properly: Choose a non-hairy, clean, dry area of skin. Press the patch firmly on your skin with the heel of your hand for at least 10 seconds. Make sure it sticks well to your skin, especially around the edges. Do not use moisturizing soap or lotion prior to applying the patch. If you are using a moisturizing soap, try changing soaps or apply medical adhesive tape over the patch to help keep it in place.
