For most people, antibiotics are considered a norm in treating sinus infections. But a new study published in the Journal of the American Medical Association has found that antibiotics did not reduce symptoms of the most common type of sinus infection (called rhinosinusitus) any faster than a placebo did. A researcher tells ABC news:
“I think patients feel awful, and they want something to feel better quickly,” said Dr. Jane Garbutt, research associate professor of medicine and pediatrics at Washington University School of Medicine in St. Louis.  “And physicians want to treat the patient.  Everyone is between a rock and a hard place.”
Antibiotics for sinusitis account for one  in five antibiotic adult prescriptions  in the United States.
