Question

Quizplus · Accepted Answer

Some cough suppressants contain opioid antitussives, such as codeine, that can be habit forming and should only be used under the guidance of a healthcare professional. Option B is incorrect because expectorants increase the amount of sputum produced in order to help clear the lungs. Option C is incorrect because mucolytics break down mucus to make it thinner and easier to cough up, but do not suppress coughing. Option D is incorrect because non-opioid cough suppressants, such as dextromethorphan, are available over-the-counter.
