I don't know if this would help but if you have been receiving your medications from a "brick and mortar pharmacy" where you actually see the pharmacist and pay the clerk, you might ask if you can get a copy of all of the scripts that they filled for you for the previous year. I don't know how far back they can go but I've had to do this before our pharmacy got a computer. Talk about time consuming! If you have a print-out showing the medications you have received, that would provide pretty solid evidence to your doctor that you have never taken the medications in questions. I get a print-out at the end of each year for use in preparing my 1040 and that information has been very useful in many ways. The doctor's office should also be able to research your previous visits and see what medications were written in your chart. You can look up any unfamiliar medications on-line at The Rx List to see if your condition could have warranted using any prescriptions that you don't recognize. As with everything in life, anymore... document, document document! All the best, Rich
