DEAR DOCTOR K: As I've entered my 50s, I find myself reaching for Tylenol more often for my aches and pains. Should I be aware of any safety precautions?
DEAR READER: Acetaminophen is the active ingredient in Tylenol and several other over-the-counter medications. As with all medications, you should use it cautiously. But if you stick to the guidelines, there's little need to worry.
