Can any antibiotic be used for bronchitis? or does it have to be a specific one.

No: Some antibiotics are better than others for bronchitis. Many cases of bronchitis are also viral, meaning antibiotics have no effect and are not necessary. Common antibiotics for bronchitis include the macrocodes and certain penicilliins and quinolones. Do not take antibiotics unless prescribed for you and when given them, take the entire course to avoid resistance issues.
