The package insert of every drug is a document carefully worded with the sole intention to deceive. And it is sanctioned by the FDA. The current leaflet for Paxil for example, lists as side effects that are very common (stated as appearing in more than 1 in 10), sexual side effects. As far as I remember, when SSRIs first came to market for at least a decade or two, sexual side effects were listed as occurring in less than 10% of the population.
Now, I don’t know of a single person who has taken an SSRI - and I have personally known more than ten people - who didn’t have sexual side effects. Maybe an exception would be the rare person who lacks any awareness of their body whatsoever. So let’s say prevalence is 90%. And yet the leaflet says more than 1 in 10. That’s a perfectly accurate statement, isn’t it?
The present leaflet for Propecia in the UK, lists sexual side effects (not permanent but ongoing) as occurring in less than 1 in 100.
Nowhere in the leaflet is it mentioned that penis shrinkage is a side effect.
These leaflets are based on evidence based medicine, reviewed and sanctioned by the FDA. Bear in mind that they have also been amended multiple times. What went wrong in medicine?
These examples are not an exception. This is the rule in today’s evidence based medicine. I can give so many examples.
