Antibiotics Too Often Prescribed for Sinus Woes

MONDAY, March 19 (HealthDay News) -- U.S. doctors are consistently overprescribing antibiotics for sinus infections, a new study finds, but even the physician who led the research doesn't see how the problem can be eliminated.

That's because when it comes to treatments for sinus trouble, antibiotics are the best of a bad lot, said Dr. Donald A. Leopold, chairman of the department of otolaryngology at the University of Nebraska Medical Center.

"We as physicians don't have very good medications for chronic rhinosinusitis," he said. "The only other drugs in contention are topical steroids, and they are not great. As a group I suggest we are frustrated at not having good drugs. It would be great if we had better medications for this chronic inflammation."

Another factor is what patients demand, Leopold said. "Many patients call up and ask for specific antibiotics," he said. "The patients know these names. They have been marketed to them, so they know the drugs are available. And antibiotics do give some relief."

His team published their findings in the March issue of Archives of Otolaryngology Head and Neck Surgery.

According to the report, two national studies show that Americans made more than 17 million visits to health-care facilities for sinus infection between 1999 and 2002. At least one antibiotic was prescribed in nearly 83 percent of cases of acute rhinosinusitis and in nearly 70 percent of cases of the chronic, longer-running version of the condition, in which symptoms persist for at least 12 weeks.

The problem is that antibiotics are effective only against bacteria, but many sinus infections are due to other causes, such as viral infections, allergies or hormonal changes. The often-repeated standard wisdom is that use of antibiotics in such cases should be avoided to reduce the emergence of dangerous resistant bacterial strains.

But it's hard to preach that wisdom to someone with a drippy, hurting sinus who wants immediate relief, Leopold acknowledged. Because more effective drugs are lacking, "patients are desperate, physicians are desperate, and it is not a happy situation," he said.
