For a dry cough, a cough suppressant (antitussive) like Dextromethorphan is typically recommended to help quiet the cough reflex. You can also use demulcents, such as throat lozenges or a spoonful of honey, to soothe throat irritation. Please avoid expectorants, as they are meant for wet coughs with mucus. Since a dry cough can be caused by allergies, viral infections, or asthma, it is important to seek a professional diagnosis if your cough persists for more than a week, or is accompanied by fever, shortness of breath, or chest pain.
