My father takes medications daily. He has had diarrhea for two weeks now. He had a stroke and was hospitalized for two days; then went to a rehab facility for two weeks. He has an appointment tomorrow with his physician and a pharmacist to go over his current medications, of which I have a list. I will attend this meeting and want to know if any or a combination of his medications could cause this diarrhea, or if c.diff should be considered and tested for.
