Most antibiotics which will work for a sinus infection will also work for strep. As a matter of fact once when one of our children had an infection the ped knew it was either a sinus infection or strep (symptoms as another poster mentioned are often similar) he decided to forgo the strep culture since he said if it was not strep he would be on antibitoics for the sinus infection anyway. He was on amoxicillin. All of the penicillin antibiotics will be effective for both.
