Over-the-Counter Erythromycin Eye Ointment: Uses, Benefits & Precautions

Erythromycin eye ointment is an antibiotic used to treat bacterial eye infections like conjunctivitis (pink eye) and to prevent infections in newborns. It works by stopping bacterial growth. This ointment is generally available by prescription only.

Uses

Erythromycin eye ointment is used to treat various bacterial eye infections. Here are some specific uses:

1. Bacterial Conjunctivitis (Pink Eye): It helps eliminate the bacteria causing the infection in the conjunctiva, the transparent membrane covering the front of the eye and lining the eyelids.
2. Bacterial Keratitis: This is an infection of the cornea, the clear dome covering the front part of the eye. Erythromycin ointment can be prescribed to treat certain cases.
3. Neonatal Conjunctivitis: Also known as ophthalmia neonatorum, this bacterial eye infection affects newborns. Erythromycin ointment is commonly used to prevent blindness in newborns by treating infections caused by bacteria like chlamydia and gonorrhea.

How It Works

Erythromycin eye ointment is a macrolide antibiotic. It works by inhibiting bacterial protein synthesis. Specifically, it binds to the 50S ribosomal subunit of the bacteria, blocking the transpeptidation process. This prevents the elongation of the protein chain, which is essential for bacterial growth and survival.

4. Close your eyes gently for 1-2 minutes to allow the ointment to spread.
5. Avoid touching the tip of the tube to any surface, including your eye.
6. Wipe the tip of the tube with a clean tissue and close it tightly after use.

Dosage and Frequency:
