Just in time for runny nose season, new research suggests routine sinus infections aren't really helped by antibiotics and other medicine that's often prescribed.

In the British study, people suffering from facial pain and a runny nose with greenish or yellowish mucus generally improved within about two weeks -- whether they took the standard antibiotic amoxicillin, steroid nose spray or fake medicine.

The results, based on patients' reporting whether their symptoms had improved, echo previous findings in children.

Antibiotics, particularly the penicillin-like drug amoxicillin, are among the most commonly prescribed medicines for sinus infections.

Steroid sprays sometimes are used, but the study found they also were no better than dummy drugs, although they appeared to provide some relief for patients with only minor symptoms.

The study should lead to a "reconsideration of antibiotic use for acute sinusitis. The current view that antibiotics are effective can now be challenged, particularly for the routine cases which physicians treat," said lead author Dr. Ian Williamson of the University of Southampton in England.

"Physicians can focus on effective remedies that improve symptom control," which include ibuprofen and other over-the-counter painkillers, Williamson said.
