Well technically you don’t have to have a fever to increase the med’s.  Fever is often the last thing to happen.  You don’t have to wait until a child get’s really sick before you start to increase either, which is what occurs by the time the child gets into fever territory.

The other thing is, when a child get’s injured or complains of a headache or toothache, they often don’t have a fever, but I would double the med’s.  I think perhaps some Doctor’s "feel" it is ok not to double because they feel it is overkill.  However, you could also look at allowing a child to get obviously much sicker before doubling as overkill also if you wanted to debte whether to double or not.  I have "followed" advise and not doubles with ear infection too, and 2-3 days later we ended up having an adrenal crsisi and hopsital admittance.  In the end I decided I was going to double when I felt I should.  I.e. when I thought there was pain, infection or illness, irregardless as to whether a fever accompanied it or not.  That if he was ill and had a fever, I would triple.  It often helped and if anything, it was only two days at the most.  whereas if they get to crisis point, it can end up 100mg shot in the butt.  Then double or triple dosing.  So this leaves you no better off in terms of overdosing.  :)
