I can see it now:
Warning, this drug will make you fat, swell at random locations all over your body, and make you dizzy, other than that, this is a great drug. Please plead with your doctor to prescribe this medication for your hypochondriac condition now.
In the event of uncomfortable side-effects, such as rashes, severe bloating, permanent disfigurements, organ failure, or death, please inform your doctor so alternative, equally harmful – but in different ways, medications can be prescribed.
In studies, most people did not find the side-effects worth the trouble of trying to convince their doctor that they really are serious side-effects (or the patient was dead so could not complain) and your quality of life actually was better before taking the medication.
What a mess we have let ourselves be led into by giving the pharmaceuticals so much power over our lives... and deaths.
