Why to bring your doctor a list of every medicine and supplement you take

Medicines can strengthen or weaken each other, and some affect test results. Your doctor can only take this into account if they know everything you take, including over-the-counter medicines, vitamins, supplements and herbal remedies.

For each item, write the name, the dose, how often you take it and since when. Add a separate line for allergies and any medicines that didn't suit you. Update the list after every new prescription.
