Most people who have sinus infections should not be treated with antibiotics because the drugs are unlikely to help, according to new guidelines from infectious disease experts. Although sinus infections are the fifth-leading reason for antibiotic prescriptions, 90 to 98 percent of cases are caused by viruses, which are not affected by antibiotics, according to the guidelines issued today (March 21) by the Infectious Diseases Society of America. Used inappropriately, antibiotics spur the development of drug-resistant superbugs, the IDSA says. "There is no simple test that will easily and quickly determine whether a sinus infection is viral or bacterial, so many physicians prescribe antibiotics 'just in case,'" said Dr. Anthony Chow, professor emeritus of infectious diseases at the University of British Columbia, Vancouver and chairman of the guidelines panel. "However, if the infection turns out to be viral — as most are — the antibiotics won't help and in fact can cause harm by increasing antibiotic resistance, exposing patients to drug side effects unnecessarily and adding cost," Chow said. A study of 166 people with sinus infections published in February in the Journal of the American Medical association showed that those who took antibiotics saw no better improvement in their symptoms than those taking a placebo.

British researchers treated 1,038 patients who had an acute lower respiratory tract infection with amoxicillin three times per day for seven days. A second group of 1,023 patients who also had a lower respiratory tract infection were treated with a placebo for the same period. The patients were age 18 or older and hailed from 12 European countries. All had had a cough for less than 28 days and were not suspected of having pneumonia.

Penicillin and amoxicillin are antibiotics, compounds that disrupt and destroy bacteria. Penicillin is the precursor to amoxicillin, and both antibiotics are derived from a mold called Penicillium glaucum. The discovery of penicillin's effect on bacteria led to a revolution in medical treatment and the development of dozens of other antibiotics, including amoxicillin, which is a cheaper antibiotic that treats a wider range of gram-positive bacteria and is less likely to cause allergic reactions. Amoxicillin was originally patented and sold under the trade name Amoxil. When the patent expired, many other patentable amoxicillin/clavulanic acid combinations of the drug were developed, including the well-known Augmentin, which is also no longer under patent.
