The quick answer - have the bottle of tylenol primed and ready to open. Let the fever rise - not much over 101, call the on-call doctor and let them tell you to eat some tylenol. They will probably tell you to take it every four to six hours and come in if it reaches a temperature over 102.5.
The other thing that has worked for me in the past - 32 ounces of iced down water with lemon - my mds fevers were almost always dehydration driven.
