With the start of the school year, I'll wager that my preschooler will bring home a cold or throat infection in a week or two. A runny nose isn't a cause for concern, but a high temperature can make a child feel miserable.

Like many parents, I keep two common fever remedies on hand: acetaminophen (Tylenol) and ibuprofen (Advil, Motrin). A new study has looked at which of these drugs works best to bring down children's fevers and whether taking both drugs together might be better than taking just one.

The study included about 150 children between 6 months and 6 years old. It found that ibuprofen worked faster and for longer than acetaminophen at reducing high temperatures. Taking both medicines together didn't seem to be any better than taking ibuprofen on its own, although children given both medicines might have had an extra couple of hours without a fever on the first day.
