1. Do not open the sachet if you are not going to use ThermaCare®. ThermaCare® may take up to 30 minutes to reach the desired therapeutic temperature. 2. Place the strip on the area to be treated, with the darker side of the thermal cells facing the skin, and adjust the strip by closing it in the front. If you are 55 years or older, use ThermaCare® over a layer of clothing and not directly on the skin. 3. For greater effectiveness, we recommend using ThermaCare® for 8 hours.
