What Is a Z-Pak Used to Treat?

A Z-Pak is a prepackaged form of the antibiotic azithromycin, sold under the brand name Zithromax 2. Like other antibiotics, a Z-Pak treats bacterial infections. Zithromax will not cure or shorten the duration of a viral infection 2. You should never take antibiotics prescribed for another person, and take a Z-Pak only if your doctor recommends it.

Patients often pressure doctors into unnecessarily prescribing Z-Paks for upper respiratory infections, although many are caused by viruses, not bacteria, according to an editorial published in the April 2007 "Journal of Family Practice." Azithromycin, like other antibiotics, can have side effects including allergic reactions, diarrhea, nausea or abdominal pain 3. Zithromax has also been associated with a small increase in the risk of cardiovascular death in some patients, the Food and Drug Administration warns 12.
