The idea of taking medication can be frightening. And as consumers and patients that want to make our own informed health decisions, it’s understandable and even appropriate to question our physicians when they recommend drug treatments. We need to understand the rationale for any medication that’s recommended or prescribed, the benefits of therapy, the side effects, and if there are any other approaches that might be more appropriate. Dietary supplements and natural health products are widely marketed as being safe and effective, and are occupying more and more shelf space in pharmacies, usually right beside the pharmacy counter. Many of my patient encounters in the pharmacy have included a discussion on the merits of drug therapy, versus the supplements that may have flashy packaging and impressive claims of effectiveness.
One encounter from my time working at a local pharmacy still sticks with me. I met a new patient who was anxious and eager to get my advice. He’d been cautioned by his family doctor that he was on the borderline of being diagnosed with diabetes. He had come to the pharmacy seeking a supplement that could help him avoid diabetes and medication. Rather than recommend any supplement, I suggested that the best approach he could probably take would be to lose some weight and get some exercise – it could be more effective than any supplement or drug, and would definitely help his health. He agreed, and then asked me what supplement he could take that could help him with some weight loss.
This type of discussion occurs all the time, and seems more common when there’s a lack of trust in the physician, or when the goals of treatment aren’t understood. The patient, reluctant to accept the physician’s recommendation, heads to the pharmacy for what they believe is a second opinion. In some cases, the patient may question the physician’s advice: “All my physician wants to do is prescribe drugs,” is a statement I’ve heard more than once. In those that are reluctant to accept medical treatment, there’s often a willingness to consider anything that’s available without a prescription – particularly if it’s perceived as “natural.” Natural products and dietary supplements are thought to be gentle, safe, and effective, while medicine may be felt to be unnatural, harsh, and potentially dangerous. Yet when I explain to patients that there’s actually little evidence to suggest most supplements offer any meaningful health benefits, I am sometimes met with puzzled or dismissive looks. The supplement industry’s marketing has been remarkably effective, glossing over the fact that the research done on dietary supplements is overall unconvincing and largely negative when it comes to having anything useful to offer for health.
