Definitely tragic, but I do not believe any liability should rest with J&J and there are many other factors not mentioned in this article that may have influenced the course (when they sought care, how soon it was recognized, if they were at a facility where they could receive adequate care, quality of care, etc) . Certainly no one likes to see it happen, however poor outcomes/adverse reactions are part of the game when dealing with drugs (yes, even OTC products). Problem is the court of public opinion has a difficult time distinguishing an undesirable outcome from liability. Certainly there is a greater risk of the unknown when dealing with newer products because the phase 3/4 trials cannot possibly enroll enough patients to detect rare adverse effects. But for a product that's been around as long as ibuprofen, I have a difficult time believing it was never discovered, reported, and added to the package insert. This case is a decade old so looking at today's package inserts is not relevant.
If someone is going agree to take a drug based on competent medical advice (or an OTC on their own), it's a reality that there may be undesirable consequences. Often, patients won't take responsibility to even learn the name and dosage of medication, let alone what it may to do their body. And we wonder about the rush to blame doctor's and drug companies? While it's easy to point the finger at Big Pharma, let's not forget about the astronomical costs of failed drugs, getting successful drugs approved, and that many diseases (HIV for one) would still be a death sentence if not for their work.
I'm not sure what the best solution for problems such as these. Perhaps a requirement that they set funds aside to help with cover medical care as a cost of doing business.
