What’s the optimum duration of antibiotics for chronic wet cough in kids?

Four weeks of amoxycillin-clavulanate is no better than two weeks of the antibiotic to resolve cough by 28 days in children with protracted bacterial bronchitis (PBB), a trial suggests.
But the researchers say the results are not clear-cut, as the time to the next exacerbation of wet cough was four times longer (median 150 days vs 36 days) in the children who stayed on the antibiotics for a month.
