                        Can anyone tell me more about this.  My mother who is 73 has had it for years and one doctor put her on a low dosage maintance antibotic and her new doctors disagree.  Can anyone help me?  Who is right?  She has not had pneumonia for 7 years, but now has it again about six months after the maintance antibotic was cancelled.
