Cephalexin: Not best choice for sinusitis, but it is is acute, the causative organism sensitive to first generation cephalosporins, and you absorb it adequately it may work well. Under the best of circumstances Cephalexin (keflex) yields low serum concentrations and entry into the sinuses in therapeutic concentrations may be problematic. Amoxicillin, trimethoprim-sulfa might also be effective.
