influenza
"Both my husband and I were diagnosed with influenza A and prescribed generic Tamiflu. I Experienced severe vomiting about 60 minutes after taking each dose. Vomiting is the most freqent side effect listed in the insert. Not sure if the few doses I took did anything at all, except for completely clearing out my stomach. My husband did not tolerate the medicine well either, although he did not have the vomiting that I experienced."
