What color cap would you typically find on a bottle of topical antibiotic eye drops?

Topical antibiotic eye drops are commonly identified by a green cap. This color coding is a standard in ophthalmic pharmacology to help clinicians and patients quickly distinguish between various classes of medications. In practice, this system aims to minimize medication errors and ensure proper administration of the right therapy.

The selection of green for antibiotic drops helps create a visual association that healthcare professionals can easily recognize. While other categories of eye drops have differing color coding—such as red for vasoconstrictors or white for artificial tears—green has become the conventional color for antibiotics. This allows for efficient organization and identification in clinical settings and pharmacy environments.
