The function of erythromycin eye ointment

Erythromycin ophthalmic ointment is a commonly used antibiotic ointment primarily indicated for the treatment of bacterial infections of the eye. Its active ingredient, erythromycin, can inhibit the growth of various bacteria, such as Staphylococcus, Streptococcus pneumoniae, and certain strains of Streptococcus. Therefore, it is commonly used to treat the following eye conditions: 1. **Conjunctivitis**: When bacterial infection causes eyelid swelling, conjunctival redness, and increased eye discharge, erythromycin ophthalmic ointment is often selected for treatment. 2. **Hordeolum**: Also known as stye, this is an acute bacterial infection of the glands at the edge of the eyelid. Erythromycin helps reduce inflammation and prevent the spread of infection. 3. **Minor eye injuries**: Such as superficial scratches or after foreign bodies enter the eye, to prevent bacterial infection. Note that erythromycin ophthalmic ointment is not effective against viral infections or allergic eye diseases. If the cause of the condition is uncertain, prompt medical consultation is recommended.
