Changing dose of drug to closest equivalent since it's no longer available

if azo 97.5 is no longer available per FDA but the 99.5 is. Can a pharmacist make that change during data verification without consulting the provider? Or will this get flagged as a med error/DV error? I know it's OTC but with the way my system workflow works, we still need to type it up, DV, and put the rx on file.
