What does DAW 0 indicate on a prescription?

DAW 0 on a prescription indicates that the prescriber has not indicated any restrictions regarding the substitution of a brand-name medication with its generic equivalent. In this context, "generic ok" signifies that the pharmacist has the authority to select a generic version of the medication if it is available. This is beneficial for both the patient and the healthcare system as generics typically provide a cost-effective alternative to brand-name drugs, while still being therapeutically equivalent.

The other options suggest restrictions or preferences that are not indicated by DAW 0. For instance, if a prescription had a DAW code indicating a brand-only request or that substitution is not allowed, it would limit the pharmacist's ability to provide a potentially less expensive generic alternative, which is not the case when DAW 0 is used.
