Cough syrups are liquid medications designed to relieve coughing and soothe the throat. They often contain active ingredients like dextromethorphan or guaifenesin, which help suppress the cough reflex or loosen mucus, respectively. Cough syrups can be classified into two main types: antitussives, which reduce the urge to cough, and expectorants, which help clear mucus from the airways. These syrups are commonly used for conditions such as the common cold, flu, or allergies. It is important to follow the dosage instructions on the label or as advised by a healthcare professional to ensure safe and effective use.
