Cough syrups are liquid medications designed to relieve coughing and soothe the throat. They often contain active ingredients like dextromethorphan for suppressing coughs or guaifenesin to help loosen mucus. These syrups can be found over-the-counter or prescribed by a doctor, depending on their formulation and intended use. Most cough syrups are categorized into two types: antitussives, which 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.
