Azithromycin 6 Tablets
What is Azithromycin?
Azithromycin is a prescription macrolide antibiotic used to treat a wide range of bacterial infections including community-acquired pneumonia, bronchitis, sinus infections, strep throat, ear infections (in children), skin infections, and certain sexually transmitted infections (STIs) like chlamydia. The classic 5-day Z-Pack (azithromycin 500 mg on day 1, then 250 mg daily for 4 days) is one of the most recognized antibiotic regimens in the US. Azithromycin works by binding to the 50S ribosomal subunit of bacteria, stopping them from making the proteins they need to survive and reproduce. A key property is its very high tissue penetration — it concentrates in tissues and white blood cells at levels far exceeding plasma levels, which allows effective 5-day courses to cover infections for 7–10 days. A licensed provider can prescribe azithromycin through Rx.com for appropriate bacterial infections. Generic azithromycin is very affordable with an Rx.com coupon.Side Effects

What Is Azithromycin?
Azithromycin (brand names: Zithromax, Z-Pak) is an oral macrolide antibiotic widely prescribed for respiratory, skin, and sexually transmitted bacterial infections. It is one of the most commonly prescribed antibiotics in the United States, known for its broad antibacterial coverage, convenient once-daily dosing, and short course duration.
What Does Azithromycin Treat?
- Community-acquired pneumonia (CAP) — mild to moderate cases
- Acute bacterial sinusitis
- Acute exacerbations of chronic bronchitis
- Strep throat — for penicillin-allergic patients
- Otitis media (ear infections) — in children
- Skin/soft tissue infections
- Chlamydia — single 1g dose (STI treatment)
How Does Azithromycin Work?
Azithromycin binds irreversibly to the 50S ribosomal subunit of susceptible bacteria, blocking the translocation step of protein synthesis. Without protein synthesis, bacteria cannot grow or replicate. High tissue penetration allows effective 5-day courses to cover infections for 7–10 days after the last dose due to slow tissue release.
Common Dosing (Z-Pack)
- Respiratory infections (adults): 500 mg on Day 1, then 250 mg once daily on Days 2–5
- Single-dose chlamydia treatment: 1000 mg (1g) as a one-time dose
- Children (weight-based): 10 mg/kg on Day 1, then 5 mg/kg daily for 4 days
Safety Notes
Azithromycin can prolong the QT interval — a concern in patients with existing heart conditions or those taking other QT-prolonging drugs. Discuss your full medication list with your provider before use.
