All these dextromethorphan-based liquids--typically labeled "adult formula," "extra strength," or "maximum strength," contain a relatively high dose of the active ingredient. They provide temporary relief of cough due to sore throat or irritated bronchial tubes, as brought on by the common cold.
Many of these products are also available in a weaker strength, usually labeled "pediatric" or "children's strength" (see Benylin Pediatric Cough Suppressant). Dextromethorphan is also available in liquid gelcaps (see DexAlone Cough Caps).
These medications may be taken every 6 to 8 hours, up to a maximum of 4 doses each 24 hours (every 12 hours for Delsym, with a 2-dose daily maximum).
