OK - so, I'm back from work - not such a long or bad day
!
Now....why a pharmacist & not just a tech reading a database?
Well....because there are exceptions to every rule. Thats part of medicine (in which I mean the treatment of ailments which encompasses both diagnosis, treatment & education).
Let me give you a few examples....
The asa/warfarin combination. First Data Bank (which is the company which provides all the drug interaction data for all pharmacy software companies) will give this interaction a "top" or "high" priority. Likewise, ciprofloxacin & warfarin will also have a "high" drug interaction.
But - this does not mean you can't give them both together. In fact, they are frequently given together......but both the prescriber & the dispenser know what they are used for & have counseled the patient on what to expect, what to look for & if they need counseling at all (the pt who is taking ciprofloxacin for 3 days for a uti & is due to have an INR drawn in 10 days anyway won't need counseling beyond what was initially given - just a simple reminder...)
Then...we can take the pt who is taking clarithromycin & amoxicillin together. Therapeutically....this would come up as a drug interaction - two drugs with similar, altho not identical spectrums.
However, you'd have to know.....that after asking the pt if they were being treated for an ulcer (H. pylorii - altho they may not know it by that name), we would know that this is a normal & expected therapeutic treatment modality (in fact, these are two components of Prevpak).
Likewise...an rx for promethazine 12.5mg q8h prn for a 6 yo for n/v doesn't seem so bad - right? However, in the last year, there has been an additional black box warning for promethazine for use in children. This black box warning basically says it should not be used at all...but, there are some circumstances in which it can & should be used. But, it needs a pharmacist to know if the circumstance is sufficient to call the prescriber or to let it ride, how much to tell the pt/caregiver, etc...
So....the whole purpose of a pharmacist (forget the degree - it can be a PharmD or a BS pharmacist) is to know what to take seriously & what not to take seriously.
Finally, we get to the law. Although each state has its own pharmacy practice statues, nearly all of them have some statement that a pharmacist shares responsibility for the appropriate dispensing of a drug. In the pharmacist terminology, dispensing involves not just counting, pouring, licking & sticking - it means evaluating if it is the appropriate drug, the appropriate dose, with counseling for the appropriate individuals.
I hope that provided some insight.
For myself, I don't worry at all about my job. There are some physicians who "dispense" from machines designed for this. They really haven't taken off & frankly, they can't keep too much stock because having the sufficient variety & quantity of drugs on hand is expensive (just ask your manager what the last inventory dollar amount was!). In some states, these machines are not legal because a prescriber cannot be a dispenser.
So....no, I'm not worried at all. I won't be working in 30 years, but some of you will be! The sky is really not falling.
Good luck!
