Cefdinir
"First sinus infection at 59 yrs old. My doc is on vacation so "nurse practitioner" prescribes cefdinir, took for 5 days, stopped because side effects,cramping,diarrhea. Was given a script of amoxicillin which knocked out the sinus problem. The cefdinir effects went away a few days after I quit them, but  as the warning says came back 8 weeks later with a vengeance. Has been 3 months now, my PCP referred me to Gastro but when I told them I had went to ER and had blood work and test for C-Diff 4 days before she called, I was told they could do a colonoscopy but if I had an inflamed colon there was nothing they could do but make it worse, if not inflamed they could prescribe a couple meds. Neg for c-diff, taken 3 bottles of probiotics, lost?"
