In brief: Cough after cold

A postinfectious cough is one that happens after a normal cold and can last anywhere from 3-8 weeks.
Once your doc makes sure nothing else is going on - like pneumonia or pertussis - then usually it's helping the symptoms. Rest assured, this usually goes away on its own. Antibiotics don't usually help, but certain inhalers can.
