Zithrocor 100 DT (Azithromycin 100 mg) Dispersible Tablets
Zithrocor 100 DT is a dispersible form of azithromycin 100 mg, a macrolide antibiotic used to treat certain bacterial infections often in children. It’s commonly prescribed for bacterial sore throat/tonsillitis, sinus infections, some ear infections, chest infections (as appropriate), and skin/soft tissue infections. Not for colds, flu, or other viral illnesses.
What Zithrocor 100 DT Treats
- Upper respiratory bacterial infections: sore throat/tonsillitis, sinusitis, some ear infections (otitis media)
- Lower respiratory infections: certain cases of community‑acquired pneumonia or bronchitis exacerbations (as advised by the prescriber)
- Skin and soft tissue infections caused by susceptible bacteria
- Other infections only when your clinician confirms a bacterial cause
How It Works
Azithromycin blocks the bacterial machinery that makes essential proteins. No proteins, no growth so the bacteria stop multiplying, and the immune system can clear the infection.
Directions & Dosage Basics
- Use exactly as prescribed. For kids, dosing is based on body weight (mg per kg).
- Typical pediatric regimens your prescriber may use include:
- 10 mg/kg once daily for 3 days; or
- 10 mg/kg on Day 1, then 5 mg/kg once daily on Days 2–5
- Give doses at the same time each day.
- Separate from aluminum/magnesium antacids by about 2 hours (they can lower absorption).
- Missed dose: Give it when remembered unless it’s near the next dose. Don’t double up.
How to Take a Dispersible Tablet (DT)
- Place the tablet in a small spoonful of clean water (about 5–10 mL).
