Treatments for a dry cough, also known as a nonproductive cough, include staying hydrated, elevating the head with extra pillows at night, using a humidifier and taking suppressants, according to WebMD. Drinking tea, lemon juice or hot water with honey may provide relief.
Quitting cigarettes or other tobacco products helps reduce a dry cough, states WebMD. When possible, it is important to avoid pollutants, smoke, dust and other irritants. Taking suppressants helps control the cough reflex, but many over-the-counter suppressants are not very effective. Severe dry coughs may require a prescription suppressant medicine.
When seeking out an ideal treatment for a nonproductive cough, it is important to determine the cause, notes WebMD. After recovering from a common cold, a dry cough often lingers for several weeks. A dry cough can also be caused by irritated bronchial tubes. If an allergy is causing the nonproductive cough, it may be necessary to take allergy medicine.
Certain medications for high blood pressure can cause a nonproductive cough, according to WebMD. Asthma is another cause of a chronic dry cough. Other signs of asthma include tightness in the chest, wheezing and shortness of breath. A blockage in the airway can cause a dry cough.
