Erythromycin Eye Ointment Usage

Erythromycin ophthalmic ointment is only available with a doctor’s prescription. It is used to treat and prevent various bacterial eye infections, including pink eye in newborns. The typical dosage for this medication is to apply it in the affected eye(s) up to 6 times a day. Most people experience few to no side effects while using erythromycin eye ointment as directed. It belongs to a group of medications called macrolide antibiotics and works by stopping the growth of bacteria, preventing them from making proteins they need to survive.

Uses of Erythromycin Ophthalmic Ointment

Erythromycin ophthalmic ointment is a medication specifically designed to treat certain bacterial eye infections. Let’s delve into its uses and effectiveness:

  1. Bacterial Conjunctivitis (Pink Eye):

    • This infection affects the conjunctiva, which is the transparent membrane covering the front of the eye and lining the eyelids.
    • Erythromycin ointment helps eliminate the bacteria causing this type of conjunctivitis.
  2. Bacterial Keratitis:

    • Bacterial keratitis is an infection of the cornea, the clear dome that covers the front part of the eye.
    • In certain cases of bacterial keratitis, doctors may prescribe erythromycin ophthalmic ointment as part of the treatment.
  3. Neonatal Conjunctivitis (Ophthalmia Neonatorum):

    • This bacterial eye infection affects newborn babies.
    • During childbirth, bacteria from chlamydia and gonorrhea infections can enter a newborn’s eyes.
    • Erythromycin ointment is commonly used as a preventive measure to avoid blindness in newborns.
    • It is applied shortly after birth to protect the infant’s eyes from potential damage caused by these infections.


  • Erythromycin ointment’s effectiveness varies based on individual factors and the specific condition being treated.
  • While it is commonly used to prevent eye infections in newborns, research shows that other treatments (such as silver nitrate and tetracycline) are equally effective.
