I know "safety" is a key concern for people before they put anything into their body, whether it's food or a pill. That's why I find it interesting when I'm asked how alli can possibly be the only FDA-approved weight loss aid.
I get asked questions like "there are so many products available in the weight loss section of stores and/or online - how can only one be FDA-approved?" The answer is that getting FDA approval for a new over-the-counter drug is a rigorous process where studies of safety and effectiveness are carefully scrutinized. Let me give you a little background.
To gain FDA approval, OTC medicines need to prove safety and effectiveness before they can be sold. When we applied for over-the-counter status for orlistat, under the name alli, we relied on the scientific knowledge gained from over 100 clinical trials, 30,000 people who had participated in clinical trials, and 28 million prescriptions written for it around the world.
By contrast, guess how many clinical trials the maker of a supplement or herbal weight loss pill needs to submit to the FDA before it's sold "over-the-counter"? None. They may have them, but they aren't required to share them.
Most people incorrectly believe that dietary and weight loss supplements are FDA approved
Millions of Americans are using dietary and weight loss supplements. In fact, according to our study conducted in 2005, one-third of respondents who have tried to lose weight report having used dietary supplements. And half the survey respondents mistakenly believed these supplements are reviewed and approved by the FDA for their safety and efficacy.
That surprising misconception was reported in a large survey conducted by the University of Connecticut (and funded by GSK). A key finding (download PDF of study abstract):
- Over 50% of those surveyed mistakenly believe the FDA approves weight loss supplements for safety and almost 50% believe the FDA reviews them for effectiveness.
It's my hunch that this kind of confusion about weight loss supplements is fueling Americans' use of unproven and potentially unsafe options that aren't approved by the FDA.
How do we change misconceptions about herbal weight loss supplements?
- How do we correct the misconceptions that people hold about the differences between weight loss supplements and weight loss medicines?
I'd really like to hear your thoughts.
P.S.
To be "over-the-counter" means you don't need a prescription to buy something from a grocery store or pharmacy. Vitamins, paper towels, weight loss supplements - they're all sold "over-the-counter." But to be an OTC (also stands for over-the-counter, are we confused yet?) medicine, a product needs FDA approval and proof of safety and effectiveness before it can be purchased by consumers "off-the-shelf."
