As of last year, according to an inspector from the Florida Board of Pharmacy I talked to, it was acceptable to fill 90 day supply on CII medications now that the DEA allows it. This is more for patients on Ritalin, Adderall etc... and where I work at, this is common and some insurance companies cover it. (this is most notably seen with Caremark & Paid) C-III drugs you can fill only a 30 day supply. (like Vicodin, Lorcet, etc...)
