MONDAY, Jan. 14 (HealthDay News) -- You've been hacking and coughing for a week now -- isn't it time that the cough was through?
Sadly, the answer is often "no," and experts report that many people have a mistaken idea of how long an acute cough should last. This misconception can lead to the unnecessary (and, for public safety, dangerous) overuse of antibiotics, a new study finds.
"No one wants or likes a lingering cough. Patients simply want to get rid of it," said Dr. Robert Graham, an internist at Lenox Hill Hospital in New York City.
"After exhausting over-the-counter regimens for about a week, they visit their doctors with the hopes of obtaining a prescription antibiotic for a self-limited condition [that is] usually caused by viruses," which do not respond to antibiotics, said Graham, who was not involved in the new study.
So how long does the average acute cough really last? The team of researchers from the University of Georgia, in Athens, reviewed medical literature and found that the average duration of an acute cough is nearly three weeks (17.8 days).
They then surveyed nearly 500 adults and found that they reported that their cough lasted an average of seven to nine days. And if a patient believes an acute cough should last about a week, they are more likely to ask their doctor for antibiotics after five to six days of having a cough, the researchers noted.
The trouble is, these patients can then be fooled into thinking that the antibiotic helped. If a patient begins taking the drug seven days after their cough began, they may begin to feel better naturally three to four days later, with the cough disappearing 10 days later. That coincides with the average duration of an acute cough and could lead a patient to incorrectly believe that the antibiotics cured their cough, the researchers explained.
Needlessly prescribing antibiotics for virus-linked coughs is another cause of antibiotic
