Doctor prescribes Serenace because patient told her to

One of the local doctors did it again. Let's call her Dr O. Dr O has appeared quite frequently in my stories here on this blog.

She wrote a script for "Serenace 100mg". No instructions. No quantity. Customer is new to the pharmacy so no patient history. 

Now Serenace is only available in the following forms:
Serenace 0.5mg tabs
Serenace 1.5mg tabs
Serenace 5mg tabs
Serenace 5mg/ml injection
Serenace 2mg/ml liquid 

So called the doctor to clarify what she meant and told her the forms available and this was her answer.

Dr: "Oh I don't know. The patient just told me to write Serenace 100mg. Just ask her to show you what she takes and just give that to her."
Me: 100mg is a very high dose. What is she using it for?
Dr: I'm not really too sure. She got it from overseas and she told me 100mg. 
Me: This is very hard for me to pinpoint what exactly she's after. It could be anything. And the dose is unusual. 
Dr: Yeh there's no point asking me. Just ask the customer. I can't help you.
Me: Ok fine. I'll ask the patient and see what I can work out. 

Seriously? How can she be a doctor. She's the one writing the script. She doesn't know what its for, and she doesn't acknowledge that the dose is one bit unusual? Instead she throws the ball to us pharmacists who have no clue what and why the patient is taking it. She relies on whatever the patient tells her to write. 

Dude, you might as well just give me your whole script pad and I'll do the prescribing for you. What's the point of having you has a doctor? Good luck to all those patients who see her. Big GOOD LUCK. I'm surprised she hasn't been audited yet. The way she runs her practice is just so........... ridiculous. 

Anyway, I asked the patient there's no 100mg and to get her to show me the old packaging. Guess what - she doesn't have it. She says its an injection. Well the 100mg injection is not available in Australia. I told her only the 5mg is available. Is that what she's after? Patient says she's not sure of the strength either. 

Everyone's not sure. The patient is not sure. Her doctor is not sure. I took the most reasonable and safest route: don't dispense anything. I am not gonna dispense anything the prescriber isn't sure of. It's her job as a doctor to diagnose and prescribe the most appropriate treatment for the patient. If its not available in Australia, then you prescribe an alternative. If you have no experience, then refer patient to a specialist who will.
