I also do not like how toxic tylenol is, but I'll echo the other (probably parents) posters pointing out that dropping a fever from 104.2 down to 100.9 is... pretty awesome when you have a screaming 6 month old and panicking mother. Arguably it's best feature is mild fever reducer. I love that feature. My child will peacefully go back to sleep within an hour of taking it and we can go get prescribed antibiotics for her ear infection first thing in the morning, rather than jumping through a bunch of hoops during a midnight run to the ER.

Ibuprofen is in almost all ways a better drug overall for parents/home use, but because of some rare reaction to it, it's not suggested until 6 months, so most parents assume Tylenol is "safer" and never switch over.
