What Is a Good Antibiotic for a Lung Infection?

Common antibiotic medications for upper respiratory infections include Amoxil, Augmentin, penicillin, Suprax and Zithromax, according to Drugs.com. Amoxil, generically known as amoxicillin, is the most commonly used and effective antibiotic to treat bacterial infections for patients who are not allergic to penicillin.

Zithromax is another commonly used antibiotic for respiratory infections including bronchitis, reports Drugs.com. The medicine is delivered in a one-dose suspension pack to counteract the infection. Zithromax is also prescribed for ear and skin infections, but it should not be used in patients with past liver, kidney or heart problems. This medication, like other upper respiratory antibiotics, does not treat viral infections.
