Note, I am not a medical profession, this is my relaying of some science around flu treatments that I do not understand. I have not been personally effected by the flu. I've been reading in various science site studies that show common medicines that lower fever - Acetaminophen and Ibuprofen are shown to lower the effectiveness of flu shots. Here is one such site; Common Pain Relievers May Dilute Power of Flu Shots Whenever I am able to get the H1N1 flu shot I'll keep this in mind. I started wondering if lowering routine flu fevers is also not a good idea, the fevers inherently are part of our bodies attempt to fight an illness, not just an symptom to control. I started asking this question at other sites, and so far am not satisfied with the responses. I walked down the closest pharmacy isle, virtually every flu medicine I can buy has something that reduces fever. I am questioning that, but can't do a study , so I post. FluTrackers and LiveScience Forums | View topic - Is a fever beneficial to fight the flu? Something definitely to consider, am I being just extreme here ?
