N/A - ready-to-use ophthalmic solution (no reconstitution or dilution required).

Stopping the Medicine

Complete the full prescribed course; do not stop early even if symptoms improve, and stop/seek care if hypersensitivity or severe irritation occurs.

Patient Counseling

Patients should be advised not to wear contact lenses if they have signs or symptoms of bacterial conjunctivitis.

Monitoring Requirements

Whenever clinical judgment dictates, the patient should be examined with the aid of magnification, such as slit-lamp biomicroscopy, and, where appropriate, fluorescein staining.

Pharmacology

Mechanism of Action

A fluoroquinolone antibiotic that inhibits the bacterial enzymes DNA gyrase (topoisomerase II) and topoisomerase IV, which are essential for bacterial DNA replication, transcription, and repair.

Onset of Action

Symptomatic improvement is typically seen within a few days; lack of improvement by about 2-3 days warrants reassessment.

Duration of Effect

Not well-defined clinically; dosing is based on labeled regimen rather than a specific per-dose duration (commonly dosed multiple times daily for conjunctivitis).
