Zithromax, popularly known as Z-Pak, is a five-day pill regimen that contains half the usual dosage of common antibiotics. It is designed to treat bacterial infections and does not work on viral infections. The common dosage for patients is a double dose on the first day and then a single dose for the next four days, according to Drug Watch.
