Hi, my neighbor has a ear infection and he received Keflex for it, 500 mg.3xaday. HE s had 1 Monday even, 3 Tuesday.3 Wed. and so far 1 today. He was taken off his Chemo, and Eljanz unti lhe finishes the Keflex. Now he s running 102.7 temp, having chills, feels horribly, weak. Should he continue on the Keflex? Also nothing taste good to him? My email is YYYY@YYYY Thank You !!!
