It is the Same Medicine!

Patient was prescribed diclofenac 75mg, but upon dispensing she said that that was not the medicine she showed the doctor. She then proceed to show me a strip of medicine. Took a look at the strip of medicine and told the patient it is the same medicine except the one she was holding is a 50mg tablet. Essentially it means when you're in pain, you need to take the medicine more frequently than a 75mg tablet.

Simple concept right? No. She insisted it was a different medicine despite me and her husband trying to explain to her that it is the same medicine, but of a different strength. Just when we thought we had finally gotten through to her, she started asking me if the 2 tablets are the same medicine. This happened about 3-4 times. Really wanted to tell her to shut up and ask her if she was paying attention to what I was telling her. If not for her sensible husband I would have done just that.
