What is the standard dosing schedule for azithromycin 15 mg/g eye drops to treat trachomatous conjunctivitis in neonates?

• A. One drop once daily
• B. One drop twice daily
• C. Two drops twice daily
• D. Two drops once daily

Answer: (B)

The key idea is how often the drop is given to keep drug levels in the neonatal eye enough to fight the infection. For azithromycin eye drops used to treat trachomatous conjunctivitis in newborns, a regimen that uses one drop in the affected eye twice daily provides sufficient local exposure to the conjunctiva while keeping administration simple and safe for the infant. Giving two drops at each instillation isn’t needed and could increase local irritation without added benefit. Dosing only once daily wouldn’t maintain therapeutic levels between applications, risking inadequate treatment. So, the standard approach is one drop in the affected eye twice daily.
