This is the quickest decision I have ever witnessed the FDA make on any issue. Just last week the FDA announced that acetaminophen laced products like Tylenol, Excedrin, and Percocet to name a few were the number one reason for liver toxicity. Now in just a few days the regulation has changed. This is good news for those of us who have always advised to steer clear of these OTC drugs, this is not so good news for those who have depended on this inexpensive way of managing pain. Also, as of today, there is no word from the FDA as to what dosage IS safe.
