@clendenin Pharmacology can be frustrating and confusing. As a geriatric woman I have several confusing and overlapping conditions, symptoms, and medications. I have learned to check into every drug I have been prescribed, look at the side effects and interactions they produce. I have been prescribed meds that I had to refuse because of med interactions and the fact that they were not really for anything. Sometimes I think Drs hope for a placebo affect and sometimes they get that affect. I guess the bottom line is you are responsible for your own health care. Geriatric patients especially need to be wary and do some investigating. I had a Dr tell me once everything in the body is connected somehow. A simple statement, but it contains a rather profound truth.
