Atozin contains azithromycin 250 mg per capsule, manufactured by Millimed Co., Ltd., Thailand. It belongs to the macrolide antibiotic class and works by binding to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis and stopping bacterial replication.
📊 The World Health Organization (WHO) lists azithromycin on its Essential Medicines List. Respiratory tract infections remain the 4th leading cause of death worldwide, making effective antibiotic therapy critically important.
Azithromycin 250 mg covers key pathogens including Streptococcus pneumoniae, Haemophilus influenzae, Chlamydia trachomatis, and Mycoplasma pneumoniae, making it suitable for upper and lower respiratory tract infections, skin infections, and certain sexually transmitted infections.
A key advantage of azithromycin is its high tissue concentration and prolonged post-antibiotic effect lasting over 5 days after the last dose. This allows a short 3-day course (6 capsules per box) to achieve efficacy equivalent to 7–14-day courses with other antibiotics, significantly improving medication adherence.
Each box contains 6 capsules of azithromycin 250 mg. Take 2 capsules daily for 3 consecutive days. Can be taken with or without food. Store below 30°C, away from light and moisture.
⚠️ Important: Complete the full course. Do not stop early, even if symptoms improve, to prevent antibiotic resistance.

About Atozin
What Is Atozin?
Atozin contains azithromycin 250 mg per capsule, a macrolide antibiotic manufactured by Millimed Co., Ltd., Thailand.
Mechanism of action: Azithromycin binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis required for bacterial growth (bacteriostatic), ultimately leading to bacterial death.
Key advantages of azithromycin 250 mg:
• Short 3-day course — 6 capsules total • Prolonged tissue effect lasting 5+ days after last dose • Can be taken with or without food • Broad-spectrum coverage against multiple pathogens
• Uncomplicated urethral/cervical Chlamydia trachomatis • Early syphilis in selected cases
Note: Azithromycin is effective only against bacteria. It does not treat viral infections such as the common cold or COVID-19.
How to Take Atozin / Dosage
Standard adult dosage (azithromycin 250 mg how to take):
• 2 capsules per day (500 mg/day) • Take for 3 consecutive days • Total 6 capsules — 1 complete box per course • Swallow with a full glass of water (approx. 240 ml)
Timing:
• Can be taken with or without food — absorption is not significantly affected • Take at the same time each day (e.g., morning and evening) • Do not crush or chew capsules
Important instructions:
• Complete the full 3-day course, even if you feel better • Never stop early — doing so risks antibiotic resistance and relapse • Missed dose: take as soon as remembered; if nearly time for the next dose, skip the missed one. Never double-dose
For Chlamydia: A single 500 mg (2 capsules) dose is sometimes used — consult a doctor or pharmacist first.
Side Effects of Atozin
Atozin (azithromycin) is generally well-tolerated. Most side effects are mild and resolve after completing the course.
• Hepatitis (rare — stop medication and seek medical attention immediately) • QT prolongation (cardiac rhythm abnormality — higher risk in patients with heart disease) • Hearing changes (very rare)
Stop medication and seek immediate medical attention if:
• Severe hives, chest tightness, or difficulty breathing (possible anaphylaxis) • Yellowing of skin or eyes (jaundice) • Severe watery or bloody diarrhea
Contraindications & Precautions
Contraindications:
• Known allergy to azithromycin, erythromycin, or other macrolide/ketolide antibiotics • History of azithromycin-related hepatitis • Congenital or documented QT prolongation (Long QT syndrome)
Special precautions:
• Liver or kidney disease — consult a doctor before use • Heart disease or concurrent use of QT-prolonging drugs (e.g., amiodarone) • Pregnancy or breastfeeding — consult a doctor • Swallowing difficulties — alternative formulations may be appropriate
Important drug interactions:
• Warfarin — azithromycin may enhance anticoagulant effect • Antacids containing aluminium/magnesium — reduce absorption; take 1 hour apart • Cyclosporine, digoxin — plasma levels may increase • Pimozide — contraindicated together (arrhythmia risk)
Children: Azithromycin can be used in children but dosing is weight-based. These 250 mg capsules are not appropriate for young children; use an age-appropriate oral suspension instead.

B-Ciprofloxacin (Ciprofloxacin) • Class: Fluoroquinolone • Course: 3–14 days (depends on indication) • Best for: UTIs, bacterial diarrhea • Advantage: Very broad spectrum including Gram-negative bacteria
Antibiotic selection depends on the type of infection and causative pathogen. Always consult a doctor or pharmacist for the most appropriate choice.
How Fast Does Atozin Work?
After taking Atozin (azithromycin 250 mg), the medication is rapidly absorbed into the bloodstream and tissues:
Action timeline:
• First 2–3 hours: Azithromycin reaches peak plasma concentration (Cmax) • Day 1–2: General improvement begins — fever subsides, throat pain reduces • Day 3 (end of course): Most symptoms should be significantly improved • After course completion: Drug continues to act in tissues for 5–7 additional days
Why does it last so long?
Azithromycin has a long half-life of ~68 hours and achieves tissue concentrations 10–100× higher than plasma levels. This prolonged tissue presence ensures continued bacterial killing after the last dose.
If no improvement after 3–5 days: Consult a doctor to assess for antibiotic resistance or the need to switch therapy.
