Priority Health requires that, when available, AB-rated generic equivalents must be used instead of non-preferred brand-name drugs. The only exception is Coumadin®.
What is an AB-rated generic drug?
AB-rated generics usually have different shapes and/or colors than their corresponding non-preferred brand-name drugs, and of course they're usually much lower in cost.
How do I know if a generic drug is AB-rated?
Pharmacies carry primarily AB-rated generic equivalents. Your pharmacist will be able to tell you if a generic drug is AB-rated.
