You’ll need to let your prescribing doctor know and ask what s/he can do about it. Sometimes the insurance will cover brand name if the doctor writes “brand medically necessary” on the Rx. But that typically takes some paperwork between doctor and insurance. You might also be able to get a smaller pharmacy to carry the brand you need for you — national chains won’t do that though because they have contracts with manufacturers.
