Cough medications are used to treat an acute cough and may also contain other medictions that ease other cold symptoms. They work in various ways, such as suppressing the cough reflex and thinning mucus. Common classes include antitussives and expectorants. Antitussives like benzonatate (Tessalon) and dextromethorphan (Delsym) are usually taken as oral capsules or liquids. Expectorants, such as guaifenesin (Mucinex), also come as oral tablets and liquids. Combination medications like guaifenesin / dextromethorphan (Mucinex DM, Robitussin DM) offer multiple benefits in one dose. These options provide different ways to help manage your cough and related symptoms effectively.
