I am taking cefadroxil 500mg x2 twice daily. I was hospitalized for an absess in my nose. during my hospitalization I had other patients in the room use the portable toilets. i am now having very liquid diahrea which I think can be a side effect of the antibiotics. I font have pain or cramping but my stomach is making a lot of noise. my concern is c.difficile. should I get tested or is the watery diahrea normal for these meds. thank you
