WASHINGTON (AP) — It’s cold season, and the miserable continue to trudge in, seeking antibiotics because of mucus turned green, or a cough that has nagged for weeks.

Despite years of warnings, doctors still overprescribe antibiotics for acute respiratory infections even though most are caused by viruses that those drugs cannot help.

Now doctors are getting new tips on how to avoid unnecessary antibiotics for these common complaints — and to withstand the patient who’s demanding one.

Sure bronchitis sounds scary. So describe it as a chest cold. And no, color changes don’t mean it’s time for an antibiotic.

“Antibiotics are terrific. Thank God we have them for really bad things. But we need to be judicious in the way we use them,” said American College of Physicians President Dr. Wayne J. Riley, an internal medicine professor at Vanderbilt University.

Rather than sending patients off with little advice about what to do while their bodies fight off a virus, how about a prescription instead for some over-the-counter or home remedies that just might ease the cough or the pain?

“We’re calling for the symptomatic prescription pad,” Riley said, describing information sheets that suggest simple aids like humidifiers and plenty of fluid, have a space to scribble directions for an OTC drug — and tell patients when to return if they’re not getting better. The Centers for Disease Control and Prevention has a sample on its website.

Antibiotics are losing their effectiveness, and inappropriate prescribing is one factor. Repeated exposure can lead germs to become resistant to the drugs. The CDC estimates that drug-resistant bacteria cause 2 million illnesses and 23,000 deaths each year in the U.S.

Another reason not to use them unnecessarily: side effects. Antibiotics are implicated in 1 of 5 emergency-room visits for bad drug reactions, CDC says. Particularly troubling is an increase in severe diarrhea caused by C-diff, the Clostridium difficile bug that can take hold in the gut after antibiotics kill off other bacteria.

CDC has seen improvement from pediatricians in antibiotic prescribing but overuse remains a big problem for adults, especially with respiratory illnesses, said Dr. Lauri Hicks, who heads CDC’s “Get Smart” antibiotic education campaign.

Monday’s guidelines, from CDC and the American College of Physicians, move beyond simple statements that antibiotics don’t work for viruses like the common cold or the flu. They lay out how doctors begin deciding if antibiotics are warranted for some other common respiratory complaints, explain that decision to patients and offer guidance on symptom relief.
