The pharmacist is the last line of defense in protecting the patient from wrong medication, doctors that make mistakes, drug interactions, and the patient. Sometimes our biggest roadblock in providing that protection is the doctor (and in this case, the DDS).
Case in point: Man, age 35, sees dentist, has root canal, gets Rx, comes to our pharmacy. He smells like alcohol and is presenting an Rx for Vicodin. This is a red flag. Alcohol is a depressant in many ways, and one thing it depresses is RESPIRATION. Add Vicodin to that mix and you have a deadly combination. Don't take my word for it... ask Heath Ledger. Oh no, you can't, BECAUSE HE'S DEAD.
I call the dentist, explaining that the patient is drunk and wants to get Vicodin filled with an Rx obtained from their office. I figure the patient stopped at the bar between the dentist and the pharmacy and I'm expecting the dentist to cancel the prescription. "Yeah, we had trouble with him today with the drinking." I'm astounded. Apparently this guy GOES to the dentist drunk, gets work done, then heads off to the pharmacy with a script for Vicodin and NO ONE at the dental office questions this...
I tell the dentist I'm not going to fill the Rx and I tell him why. When Mr. Drunktooth comes back for his Vicodin, I politely tell him why I can't fill his prescription and that it could possibly be a serious situation to take it given his condition. I mean, seriously, the guy is having a hard time standing up and the dentist just wants me to hand over a bottle of Vicodin to him?
