Why must some ointments be labeled for specific uses like "ophthalmic"?

Labeling ointments for specific uses, such as "ophthalmic," is crucial to prevent misuse and ensure safety. Ointments designed for the eyes have specific formulations and ingredients that are safe for use in that sensitive area. If an ointment intended for ophthalmic use is used inappropriately, it may lead to serious harm or adverse effects, such as irritation, infection, or more severe complications.

Proper labeling informs healthcare providers and patients about the intended area of application and the appropriate usage. It reduces the risk of errors that could arise from using a product for a purpose other than what it was designed for, thereby safeguarding patient health. In contrast, aspects like marketing source, absorption rates, or flavor differences do not pertain to the critical necessity of ensuring the correct and safe application of ointments.
