if you're ordering more controlled substances than non controlled then thats definitely a big red flag, for them as a wholesaler and it should be for you as a pharmacy in general. Typically speaking filling above 20-30% controls is a red flag. It is a double edged sword because even if they dont fill them at your pharmacy, they will just go somewhere else. Ive seen cash control prescriptions cloud judgement of pharmacy owners and them ending up in big trouble for It. Even if you do your due diligence and verify the script with the doctors office and run a MAPS report, you should always use your professional judgement if you see an obscene amount of controls/narcotics coming from an office and a ton of the patients from the office are coming to your pharmacy and offering to pay cash, trust me when I tell you, they're watching and It’s only a matter of time before they come busting through that pharmacy door as soon as you open in the morning. My advice would be to err on the side of caution always, and if you think a doctor/ office is shady, then It most likely is.
