there are probably more, starting with aspirin (salicin), modern opioids (opium) and modern anticholinergics (atropine). there’s also plenty of stuff in traditional medicine that maybe does nothing beneficial or even kinda works but it’s way too toxic for modern regulatory agencies, like all heavy metals and aconitine

“Big pharma” companies do have a potential interest in covering up the harms of medicines in their patent rosters. If it doesn’t straight up kill their customers, it’s less money they have to spend on R&D for less harmful treatments.
Not to imply random snake oil assholes selling ivermectin etc. don’t have similar, worse interests. But no one in the space whatsoever is just immune from standing to gain from doing something bad without serious oversight from all angles.
