Penicillin eye ointment is an antibiotic treatment used for bacterial eye infections such as conjunctivitis or blepharitis. It contains penicillin, which works by inhibiting bacterial cell wall synthesis, thereby stopping the growth of bacteria.

Apply a small amount of the ointment to the lower conjunctival sac of the affected eye(s), usually 2-4 times a day, as directed by your healthcare provider. Avoid touching the tube tip to your eye or any surface to prevent contamination. Use the ointment for the full prescribed duration, even if symptoms improve.

Common side effects may include mild eye irritation, redness, or temporary blurred vision. If these side effects persist, consult your healthcare provider for further advice.
