Sinusitis
"I have never taken an antibiotic without experiencing at least some negative side effects due to being extremely sensitive to most medications. Omnicef/Cefdinar is the only antibiotic my body tolerates with zero negative side effects. Over the years I have taken it for respiratory infections, including sinus, and also for UTI/kidney infections. I am beyond grateful there&#039;s at least one medication like this one I can tolerate."
