NuVet: Pet Supplement Snake Oil

I’m a dog person. I always wanted a dog as a child, and while my extended family all had dogs, we never had one in our home. I finally got my wish just over a decade ago. My wife and I were referred to a breeder with an excellent reputation for raising healthy, family-friendly Labrador Retrievers. Within moments of meeting a tiny...

Multiple Chemical Sensitivity: Separating facts from fiction

Does multiple chemical sensitivity exist? The symptoms certainly do, but it's less clear if they are due to "chemicals".

Dr. Oz and the Terrible, Horrible, No Good, Very Bad Day

Dr. Mehmet Oz is one of the most well-known, and possibly the most influential medical doctor in America. The Dr. Oz Show is broadcast in 118 countries and reaches over 3 million viewers in the USA alone. When Oz profiles a product or supplement on his show, sales explode – it’s called “The Dr. Oz Effect”. Regrettably, Oz routinely and consistently gives...

Don’t supplement users deserve consumer protection, too?

The Canadian Parliament, hypothetically protecting consumers since Confederation. One of the most pervasive yet appealing health myths is the idea that natural equals safe. It’s a statement that’s repeated constantly by manufacturers of supplements and “natural” health products. It’s been the primary argument used, with considerable success, to give these products completely different regulatory structures than exist for drug products. Weaker regulation...

Beware the Integrative Pharmacy

Imagine a retail pharmacy where some of the medicines on the shelves have been replaced with similar-looking packages that contain no active ingredients at all. There is no easy way to distinguish between the real and the fake. Another section of the store offers a number of remedies with fantastic claims, such as “boosting” the immune system, “detoxifying” the body, or “cleansing”...

We’re a drug-taking, supplement-taking nation. So how do we do so safely?

Do you take a vitamin or dietary supplement? It’s increasingly likely that you do, as over half of all American adults took some sort of supplement over the past 30 days. Now there’s evidence to suggest that about one-third of all Americans are taking supplements and prescription drug at the same time, which is renewing questions about risks and benefits. The same...

Naturopathy vs. Science: Vaccination Edition

We saw it coming. The re-emergence of vaccine-preventable disease should surprise no-one that’s been following the anti-vaccine movement. Rebutting anti-vaccine rhetoric feels like a Sisyphean struggle. Steven Novella likened it to a game of whack-a-mole, where the moles are the same old tropes that keep popping up, no matter how often they are refuted with facts. Vaccines are a remarkable success of...

New evidence, same conclusion: Tamiflu only modestly useful for influenza

Does Tamiflu have any meaningful effects on the prevention or treatment of influenza? Considering the drug’s been on the market for almost 15 years, and is widely used, you should expect this question has been answered after 15 flu seasons. Answering this question from a science-based perspective requires three steps: Consider prior probability, be systematic in the approach, and get all the...

More questions about acetaminophen: Does it cause ADHD?

“Will Tylenol harm my baby?”   Pharmacists are among the most accessible of health professionals, and so we receive a lot of questions from the public. No appointment required, and the advice is free. Among the most frequent sources of questions are women seeking advice on drug use in pregnancy. This is an area where some health professionals are reluctant to tread....

Naturopathy vs. Science: Allergy Edition

I glanced at my pharmacy license recently, and noticed I became a licensed pharmacist almost exactly twenty years ago. Two decades seems like a long time to do pretty much anything, yet I can still vividly recall some of the patients I encountered early in my career, working evenings in a retail pharmacy that drew heavily on the alternative medicine crowd. It...
