Z-Pak stands for Azithromycin 5-day dose pack, a drug abbreviation.

Brand-name blister pack of six azithromycin 250 mg tablets, taken as two tablets on day 1 and one daily on days 2 to 5. The name has become everyday shorthand for a short course of azithromycin.

Example: Patient asking for a Z-Pak for a 3-day cold; explained antibiotics won't help a virus.

Usage notes

Zithromax Z-Pak is a Pfizer brand, and generics are sold as azithromycin dose packs. Azithromycin lingers in tissues for days, which allows the short course. It is often requested for viral infections where it has no benefit, contributing to macrolide resistance in Streptococcus pneumoniae. The FDA warned in 2013 about rare fatal heart rhythms.
