I came home from school with a horrible cough. My 91 year old mom now has it. Dr. said antibiotic was up to me. I am worried about her having or getting pneumonia. He said if it was viral it would just run its course & I should give liquids. He prescribed Azithromycin in case it was bacterial, BUT he didn't know if I should give it to her & it was up to me. She had a fever the first night 100.5 & I gave her regular Tylenol, but she hasn't had a fever since. She seems alright except for this cough that could be bronchitis & she seems to have a lot of mucous. I read the printout on the antibiotic and it mentions that people with heart problems shouldn't take it. She has had AFIB, high blood pressure, and a thickening of the Aortic wall? I tried the antibiotic first since we both must have the same bug. I had diarrhea for two days & don't feel much better, but exhausted. I still have a cough, but not as violent. I have had this for about 9 days. The antibiotic you take for 5 days with 2 the first day and I have 2 more to go. I don't want her to have to go through it if it doesn't do any good. I also don't want her cough to turn into pneumonia since she is bed bound. She doesn't want to go to the emergency room. I could call the doctor again since I doubt that he remembered anything about her heart, but he usually says that she is a puzzle & it's hard to figure. She doesn't seem to be in any distress EXCEPT when she has these coughing spells which was twice last night and twice today. Any recommendations? Thanks!
