sinusitis
"Went to Urgent Care for an upper respiratory infection.  Cefdinir after 1 day helped with the respiratory problem but left with suffering with intolerable diarrhea.  I'm taking probiotics and just had to take a Lomotil.  No pain but just pure and simple constant running to the bathroom.  I'm 70 years old and consider myself an athlete and very strong. Rarely sick but this has taken me down,  I stopped the Cefdinir after 5 days.  Could not take it anymore."
