1318 drug-induced adverse events were not reported in published study of weight loss drug orlistat

“For one trial [of the weight loss drug orlistat (Xenical, Alii)], we identified an additional 1,318 adverse events that were not listed or mentioned in the [clinical study reports] itself [or the published paper] but could be identified through manually counting individual adverse events reported in an appendix, ” according to an analysis of orlistat studies by Prof. Peter Gotzsche, MD and others from the Cochrane Collaboration.
Is the same thing true for studies of other drugs?
Do you believe that this is also true for studies of cholesterol drugs (statins) and blood pressure drugs and diabetes drugs and antidepressants and anti-anxiety drugs and sleeping pills and bone-building drugs and acid-blocking drugs and every other drug out there?
Yes, of course it is.
I believe drug-induced side effects are dramatically underreported
I believe that drug-induced side effects are dramatically underreported in all drug studies sponsored by the drug companies.
This is just one example to prove this.
I no longer believe any drug studies
This is why I no longer believe any drug study sponsored by the drug companies or any review paper written by anyone paid by the drug companies as I wrote about here.
What the drug industry publishes should be viewed as an advertisement and nothing else
This is why Prof. Peter Gotzsche, MD, cofounder of the Cochrane Collaboration, said “What the drug industry publishes, even in the New England Journal of Medicine, should be viewed as an advertisement, and nothing else,” as he stated in the video clip posted here.
