A lot of drugs advertised on TV list a bevy of side effects. I have a friend whose son took Tylenol on a regular basis for years for back pain. He now has liver damage caus3d by the Tylenol so bad that he’s been given 5 years to live and he is in constant pain. I have recently seen ads for Tylenol on TV and nowhere does it mention that it can cause liver damage.
Any product that is truthful and legal can potentially be advertised. The FDA could require oversight, however, rather than allowing the pharma industry to regulate itself.
