How to Use ThermaCare® HeatWraps
How do I put the HeatWrap on? Which side goes toward my body?
Can I reuse a ThermaCare® HeatWrap if I don’t wear it the full 8 hours?
- No, ThermaCare® HeatWraps are designed for single use and provide long-lasting, powerful pain relief and relaxation of tight muscles by delivering real heat.
- ThermaCare® works by using iron particles that start reacting when exposed to air. This reaction gives off heat. Once the iron is used up, it can’t be reactivated or recharged. So after the product stops heating, it won’t reheat and should be disposed of properly. ThermaCare® should not be used in microwave ovens, as the HeatWrap may catch on fire.
Can I cut the HeatWrap to a different size to fit different areas of my body?
No, definitely not. Cutting the HeatWrap may damage the heat cells. Damaged heat cells can lead to increased risk of burning. Don’t use a HeatWrap that has damaged or cut heat cells.
I accidentally cut or tore the HeatWrap or damaged the heat discs. Can I still wear it?
No. If the HeatWrap is damaged or ruptured, contain the contents and dispose of it properly. If you’ve ingested any of the contents, rinse your mouth with water and call a Poison Control Center immediately. If heat cell contents come in contact with your skin or eyes, remove wrap, rinse affected area with water, and seek professional assistance immediately.
How many HeatWraps can I use at one time? Sometimes I need help in more than one area (like my knee and my shoulder).
You can safely wear more than one ThermaCare® HeatWrap as long as they’re in different locations. Don’t wear more than one HeatWrap in the same place at the same time. Be careful not to overlap heat cells or wear any HeatWraps under tight-fitting clothing, belts or waistbands. Check your skin frequently during use, and if you find irritation, stop use immediately.
How long should I wear a ThermaCare® HeatWrap?
For best results, wear ThermaCare® for the full 8 hours. Using ThermaCare® for more than the recommended time can increase the risk of skin irritation or burns. ThermaCare® shouldn’t be used more than 7 days in a row. ThermaCare® Menstrual HeatWrap shouldn’t be used more than 4 days in a row. If during or after this time the pain you’re treating remains unchanged or worsens, consult your doctor, as this may be a sign of a more serious condition.
Can I attach the ThermaCare® Menstrual HeatWrap to my skin?
No. The fastening adhesive on the ThermaCare® Menstrual HeatWrap wasn’t designed to be attached to the skin. ThermaCare® Menstrual should be attached to clothing so the dark sides of the heat cell are against your skin. Do not apply the adhesive to your skin; it may cause irritation. If applied incorrectly, the device may not work properly.
How will I know whether or not ThermaCare® has heated up to the correct temperature? How long does it take for ThermaCare® to warm up?
ThermaCare® has warmed up when it feels warm to the touch. Extensive testing has shown that ThermaCare® heats to about 104°F (40°C) within 30 minutes and maintains this temperature for 8 hours.
Can I wash the HeatWrap?
Don’t wash or moisten a ThermaCare® HeatWrap because it will deactivate the heat cells. While excessive moisture or wetness will affect the ability of the heat cells to heat efficiently, average body perspiration will not affect the HeatWrap performance.
