Clarithromycin
upper respiratory tract infection
"I'm either allergic or suffer severe side effects to all antibiotics I've tried with the exception of Clarithromycin & Ciprofloxacin. I've been taking Clarithromycin as my preferred antibiotic for over 20 years. I'm sorry to see so many people have issues with it. Maybe people like me who have always had very positive results just don't post. I do not have any side effects & have used it for everything from pneumonia to upper & lower respiratory infections. I have severe asthma so it is extremely important to stop any respiratory infection ASAP. Everyone is different pls don't dismiss this antibiotic without discussing it with your doctor & their other patients opinions. Personally, it is my antibiotic of choice."
