4. Remove Irritants From the Air
Perfumes and scented bathroom sprays may seem benign. But for some people they can cause chronic sinus irritation, producing extra mucus that leads to chronic cough, says Alan Weiss, MD, a general internist at the Cleveland Clinic. Take control by avoiding such scented products.
The worst irritant in the air is, of course, smoke. Almost all smokers eventually develop “smoker’s cough." Everyone around the smoker may suffer from some airway irritation. The best solution? Smokers need to stop smoking. (Yoder warns that severe chronic cough can be a sign of emphysema or lung cancer in smokers, so see a doctor if you’re a smoker with chronic cough.)
5. Take Medications to Treat Coughs
When steamy showers, hot teas, and cough drops don’t help, you can turn to over-the-counter medicines to ease your cough.
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.
Cough suppressants and expectorants: If you’re coughing so much that your chest hurts and you’re getting a bad night’s sleep, consider a cough suppressant such as dextromethorphan, Mosnaim says. Yoder recommends using cough suppressants only at night.
When a person has a cough that is thick with phlegm, Mosnaim says it helps to take a cough expectorant such as guaifenesin. Expectorants thin out the mucus so one can more easily cough it up, she says.
Note: The FDA advises against giving cold and cough medicine to children under age 4. These common over-the-counter drugs can cause serious side effects in young children.
