The number of Rx drugs that made it to FDA approval and were later found to have an unacceptable level of side-effects, is not insignificant.I think most drugs go through a least a moderately decent testing when they’re being developed. At least for their initial intended purpose.
Here’s my concern. When drugs start getting prescribed for new issues and new clientele they aren’t always vetted as well. So how many years before they discover some deadly side effect for this new target audience?
