Cough syrups are liquid medications designed to relieve coughing and soothe the throat. They can contain various active ingredients, such as dextromethorphan for suppressing coughs or guaifenesin for thinning mucus. These syrups are often used during colds, flu, or allergies to provide comfort and ease breathing. Cough syrups can be classified into two main types: antitussives, which help reduce the urge to cough, and expectorants, which help clear mucus from the airways. It's important to follow dosage instructions and consult a healthcare professional if symptoms persist or worsen.
