Dextromethorphan is contraindicated in patients with COPD. It may cause sedation at low doses. If a cough lasts longer than 1 week, patients should be instructed to contact their provider and not to continue to treat with over-the-counter antitussives. Alcohol can cause excess sedation when taken with dextromethorphan.
