Proper labeling of ophthalmic preparations is essential for patient safety, sterility assurance, and regulatory compliance. This topic covers label elements such as product name, strength, concentration, preservative information, excipients, batch number, manufacturing and expiry dates, storage conditions, directions for use, warnings like “For ocular use only” and single‑use versus multi‑dose indications. B. Pharm students must understand regulatory requirements, beyond‑use dating, container‑closure system labeling, and instructions for suspension/ointment formulations.
