Chough can be explained as to expel air from the lungs with a sudden sharp sound. Chronic cough is defined as a type of cough which lasts for minimum eight weeks or longer in adults and four weeks in children.
An upper respiratory tract infection like a cold or flu causes postnasal drip. Extra secretions trickle down the back of your throat, irritating it and sometimes causing a cough. Drinking fluids helps to thin out the mucus in postnasal drip. Drinking liquids also helps to keep mucous membranes moist. This is particularly helpful in winter, when houses tend to be dry, another cause of cough, he says. Decongestants come in pills, liquids, and nasal sprays under many brand names. Look for phenylephrine or pseudoephedrine as the active ingredient in decongestants taken by mouth, but be careful. These medicines can raise blood pressure, so people with hypertension, heart disease or other medical problems need to be careful with their use. Also, overuse of decongestants can lead to excessive dryness, which can trigger a dry cough. Decongestant nasal sprays, if used for more than 3 or 4 days, can lead to rebound congestion, Mosnaim says. It’s best to use them for 2 or 3 days and then stop.
Antihistamines and decongestants, Inhaled asthma drugs, Antibiotics, Acid blockers, Cough suppressants should be used for cough suppression.
