My husband is in a nursing facility and recently they found the staff had left 3 patches on his back. They have reassured me that he was not overdosed. He appeared flush to me prior to our discovery, but he had no temperature. He has been complaining of a sore feeling in his stomach area (traditional heartburn area). They have checked his stool for blood and have not found any. Should I be concerned? What is typical for handling an overdose of this type?
