A cough that continues despite antibiotics does not always indicate a bacterial infection and should be evaluated according to its underlying cause."
What Causes Chronic Cough? Persistent Dry Cough, Antibiotic-Resistant Cough and Relief Methods

What Is Persistent Cough?

Persistent cough is generally defined as cough lasting more than eight weeks in adults. Chronic cough often signals an underlying cause rather than being a disease itself.

What Causes Chronic Cough?

Chronic cough has multiple causes including reflux, asthma, postnasal drip and smoking-related irritation.

Why Does Cough Continue Despite Antibiotics?

Persistent cough despite antibiotics may suggest a non-bacterial cause such as reflux or airway sensitivity.

What Causes Persistent Dry Cough?

Persistent dry cough is commonly associated with airway irritation, allergies and reflux.

Reflux Related Cough

Silent reflux may trigger persistent cough even without classic heartburn symptoms.

Can Allergies Cause Chronic Cough?

Postnasal drip and allergies are among the most common reasons for chronic cough.

Can Asthma Present Only With Cough?

Cough variant asthma may appear without classic wheezing symptoms.

What Helps Persistent Cough?
