Cough Medicines a Bust?
Lung Experts: No Evidence Over-the-Counter Cough Medicines Work; May Be Harmful in Kids
Jan. 9, 2005 -- Over-the-counter cough medicines may be a waste of time and money, says a panel of America's top lung specialists.
Consumers spend billions each year on nonprescription cough syrups, drops, and so-called cough and cold medications. But an expert panel concluded that these products rarely help a cough.
"There is no clinical evidence that over-the-counter cough expectorants or suppressants actually relieve cough," says panel chairman and pulmonary specialist Richard D. Irwin, MD.
The updated cough treatment guidelines were issued by the American College of Chest Physicians and are published in the January issue of its journal Chest. They are endorsed by the American Thoracic Society and the Canadian Thoracic Society.
Nondrowsy No Good
So what should you do instead to relieve that irritating cough?
The panel recommends the use of older antihistamines with a decongestant for the treatment of coughs due to colds, allergies, and sinuses in adults. They specifically suggest the antihistamine brompheniramine and the decongestant pseudoephedrine, both found in many over-the-counter cold remedies.
The anti-inflammatory pain reliever naproxen (Aleve, Naprosyn) has also been shown to be effective for cold-related coughs, the report states.
Newer antihistamines, which are nonsedating, are not effective for treating coughs, Irwin tells WebMD.
"If you take an [antihistamine] medication that says 'nonsedating' or 'nondrowsy' on the label, it isn't going to do anything for your cough," he says.
Each year in the United States, roughly 30 million Americans see their doctors because of coughs.
"Cough is the No. 1 reason why patients seek medical attention," Irwin says. "Although an occasional cough is normal, excessive coughing or coughing that produces blood or thick, discolored mucus is abnormal."
ACCP President W. Michael Alberts, MD, tells WebMD the guidelines were updated to reflect new research on the treatment of coughs.
Kids and Cough Medicine
While the revised ACCP guidelines stop short of saying that adults should not take over-the-counter cough medications, this was the group's recommendation for children under the age of 15.
"Cough and cold medicines are not useful in children and can actually be harmful," says Irwin, who is chief of the division of pulmonary, allergy, and critical care medicine at the University of Massachusetts Medical School.
