State DAW Laws

DAW Laws at the State Level

Follow your state-specific guidelines to ensure your patients’ UNITHROID prescriptions are filled as you intend.

Generic Substitution Law Key

Permissive: If prescription is not written to ensure UNITHROID is dispensed, generic substitution is permitted.1

Mandatory: If prescription is not written to ensure UNITHROID is dispensed, generic substitution is mandatory.1

Orange Book: Pharmacist must select a substitute product listed as therapeutically equivalent in the FDA Orange Book.1

Individual Determination: Pharmacist must select from a state drug formulary, typically narrowed down in the FDA Orange Book.31,32

Professional Judgment: In the pharmacist’s professional judgment, the substituted drug is therapeutically equivalent and interchangeable to the prescribed drug.13

Patient Consent: Patient notification and/or consent is required to substitute.1

Considerations for other prescribing methods

  • Generally, e-prescriptions should mirror language used on written prescriptions
  • Depending on the e-prescribing software, you may need to take additional steps to indicate that a generic should not be substituted. For example, you may need to uncheck a default “substitutions allowed” box or click a pop-up to confirm that you intend to prescribe a brand-name product
  • Orally communicated prescriptions should use the same language required for written or electronic prescriptions
