Methadone Rx

Hi everyone, There's a patient who has been filling methadone (~12 tabs/day= 120 mg) and klonopin at the pharmacy for almost 3 years. Upon review of the state's PDMP report, that's 369 mgEq/day. Per the dr's office the diagnosis code is M54.5 for chronic low back pain. I am relatively new to the pharmacy, and am not feeling comfortable filling the script. Under what circumstances, if any, would you fill the Rx? What if I don't fill it and the patient ends up going through withdrawal...? Any... Methadone Rx
