I've been given the wrong dose of medication by a doctor (clicked the wrong button apparently!), he gave me 5 x the dose I should have been on which only came to light when I went back to see another GP due to the side effects. I had a Dr give me a prescription for some antibiotics the other week which I had to tell her I could not take for a number of reasons (just as well I'm big on reading up about my conditions and medications else who knows!).
I've also been handed the wrong prescription a few times. Randomly there are two people are my surgery with "my" name, albeit a slightly different spelling. It's not that usual a (real) name.
I've had a prescription randomly delivered before from a pharmacy I've never been to and left with my neighbours so I'm guessing she has had some of mine too.
We've been called in to the wrong Dr before now and that only came to light when an age issue came up - she said no problem with me being under 30, I pointed out I was 34, she said the screen said I was 24.....
I'm guessing something else might have happened recently as they all seem to be double-checking which one I am lately.
Someone I know was given some kind of sedative instead of some completely different drugs she was meant to have. She was phoned and asked to come back...while she was driving on the way to pick up young children!!!
