What does "DAW 0" indicate on a prescription?

"DAW 0" on a prescription specifically indicates that no product selection is indicated. This means that the prescriber has not specified any preference for a brand-name drug over a generic version, allowing the pharmacist discretion in choosing either option based on what is available or what may be the most cost-effective choice for the patient.

In practice, when a prescriber uses "DAW 0," they are essentially stating that they will accept whatever formulation the pharmacist deems appropriate—whether that be a generic version or the brand-name drug—therefore facilitating generic substitution if it is available. This is a common practice aimed at improving medication adherence and managing healthcare costs. Thus, it provides flexibility for both the pharmacist and the patient in fulfilling the prescription.
