Zithromax vs Azithromycin: are they the same?
Zithromax is a commercial brand whose active ingredient is exactly Azithromycin. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Zithromax contains Azithromycin as its active ingredient. Talking about "Zithromax" in clinical terms is the same as talking about Azithromycin at the dose strengths 250mg, 500mg, 600mg.

The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
