Many medication problems begin with questions that were never asked. When a new medicine is prescribed, ask what it is for and how soon you should notice an effect. Ask exactly when and how to take it, including whether it should be taken with food, and what to do if you miss a dose. Ask about common side effects, which ones are reasons to call the clinic, and which usually settle within a couple of weeks.
Tell your doctor about everything else you take, including herbal remedies, supplements and over-the-counter painkillers, because some combinations raise blood pressure or interact with prescription drugs. Ask how long you are expected to take the medicine and never stop a long-term treatment simply because you feel well. Store tablets in a cool, dry place in their original packaging, and check expiry dates. A written medication list that you update after every visit is one of the most useful safety tools you can own.
