What does "UAD" mean when written on a prescription?

The abbreviation "UAD" on a prescription stands for "Use as directed." This notation instructs the patient to follow the dosing instructions as provided by the prescribing physician. It is a common phrase used in pharmacy practice to guide patients on how to take their medication properly without specifying an exact dosage. This can be crucial for medications where dosing may vary based on the individual's response, the condition being treated, or other factors such as dietary considerations.

Understanding that "Use as directed" can cover a variety of scenarios allows patients to recognize the importance of adhering closely to the physician's guidance rather than applying a one-size-fits-all approach to medication management. In contrast, the other options propose specific directives related to timing, units, or preparation of medication, which do not convey the same level of flexibility that "Use as directed" provides.
