Looks like that poster is in a completely different category from the general population. It says so in your quote as well: "does not appear to _generally_ outweigh the side effects".

That's a rather common mistake and I'd guess many doctors do it as well. Treatment risk depends only on alternatives. A pill that gives your a 0.01% chance of sudden death is an absolute no-go for genpop, but may be heaven-sent for a particular patient.
