How long should I wear a ThermaCare HeatWrap?
For best results, wear ThermaCare for the full 8 hours (12 hours for Joint & Arthritis Pain products). Using ThermaCare longer than 8 hours (12 hours for Joint & Arthritis Pain products) can increase the risk of skin irritation or burns. Use ThermaCare Joint & Arthritis Pain for the full 12 hours. ThermaCare and ThermaCare Joint & Arthritis Pain shouldn’t be used more than 7 days in a row; ThermaCare Menstrual 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 physician, as this may be a sign of a more serious condition.
