Answer

Dextromethorphan, a centrally acting cough suppressant, may be considered for the treatment of postinfectious cough in adults if other medications fail. However, this agent may have limited efficacy in treating cough related to acute URI. One study showed that honey was superior to dextromethorphan in reducing cough symptoms and improving sleep in children with URI. [50]
