A young man hands you a dental prescription for 21 metronidazole 200mg tabs i tds. You dispense the medicine and counsel him to avoid alcohol – and he looks worried.
"I'm going on a stag do this weekend – of course I'm going to drink!"
You explain the consequences of drinking on the medicine, and the man grins.
"Well, I can just not start taking it until after the weekend, can't I? That won't be a problem, will it? How long do I need to wait before I start it?"
How would you reply and what are the consequences of your choice? Post your comments at chemistanddruggist.co.uk/practice and we will publish the best responses in C+D next month
