How Does Erythromycin Ointment Work?

Erythromycin interferes with the protein production of bacteria, preventing them from growing and multiplying. By controlling bacterial growth, the infection is cleared and further spread is prevented.

• Dosage: Usually a ribbon of ointment (~1 cm) is applied directly to the inside of the lower eyelid of the affected eye(s), typically 2-6 times daily as prescribed.
• Neonatal Use: For newborn prophylaxis, a single application is usually given in each eye soon after birth.
• Instructions: Wash hands before application. Avoid touching the tip of the tube to prevent contamination.
• Contact Lenses: Remove contact lenses before using the ointment and wait until infection has cleared and treatment is complete to resume use.

• Rare but Serious: Severe allergic reaction; seek medical attention if symptoms like rash, itching, swelling, severe dizziness, or trouble breathing occur.
