Hi, A nonproductive cough is dry and does not produce sputum. A dry, hacking cough may develop toward the end of a cold or after exposure to an irritant, such as dust or smoke. There are many causes of a nonproductive cough, such as: - Common cold - Allergies - Exposure to dust, fumes, and chemicals in the work environment - Medicines called ACE inhibitors that are used to control high arterial presion Home Treatment include: - Prevent dehydration. Fluids may help thin secretions and soothe an irritated throat. Dry, hacking coughs respond to honey in hot water, tea, or lemon juice. -Elevate your head with extra pillows at night to ease a dry cough. - Try a cough drop to soothe an irritated throat. Expensive medicine are no better than inexpensive candy. - Flavored drops or hard candy. Most cough drops have no effect on the cough-producing process. - Use a humidifier to add moisture to the air. Use only water in the humidifier. - Quit smoking and do not use other forms of tobacco, especially while you have a cough. - Avoid exposure to inhaled irritants, such as smoke, dust, or other pollutants, or wear a face mask that is appropriate for the exposure. Many kinds of face masks are available. Hope my answer was helpful. Let me know if I can assist you further. Regards, Dr. Dorina Gurabardhi
