Dear customer, There are many causes for cough.Infectious causes of acute cough include viral upper respiratory infections (the common cold), sinus infections, acute bronchitis, pneumonia, and whooping cough. The noninfectious causes of cough include flare-ups of chronic conditions such as chronic bronchitis, emphysema, asthma, and environmental allergies. You should have the sputum examination, chest x-ray and blood counts done after consulting a doctor.The bacterial infection if present needs to be treated with suitable antibiotics like augmentin, azithromycin, ofloxacin etc.. The cough that are caused by allergies are often relieved with allergy medication, and coughs due to environmental irritants will respond to elimination of the irritating agent. The over-the-counter or prescription cough remedies are also available to control the symptoms.Though the treatment depends on the underlying cause. thank you
