i don't know how you were diagnosed or if the strep diagnosis was correct. if it was a rapid strep test or culture then the diagnosis would be accurate and the keflex should be helpful. if it was just a "look and see" diagnosis based solely on appearance then i would question that you have strep. if you have a viral infection even mono the antibiotic would be totally ineffective.
been on keflex for 4 days now for strep and am really no better. is this common?
