It's not directly related to end-of-life issues ... but two painkillers, Percocet and Vicodin, do include acetaminophen, and they are sometimes used in palliative care. And, one of the recommendations made to the FDA was to ban Percocet and Vidodin.
I'm posting the link because it's an excellent hour of radio and an important issue for everyone to stay informed on.
If for no other reason than who hasn't taken two tylenol or two Excedrin when they had a headache? And an interesting tidbit from these recommendations: two pills at once may be too much acetaminophen for your liver to healthfully process.
