My husband is 97 years old. he has CHF, Parkinson Disease, Diabetes, and cronic UTI's. His family doctor put him on ferrous sulfate and ever since that he has had terrible night sweats, to the point that you could almost ring the sweat out of his pajamas. He is also taking Cipro for the UTI infections. I cannot get the doctor to respond to my questions about him using the ferrous sulfate with the Cipro. Please help!!!
