Cough syrup is a liquid medication designed to relieve coughing and soothe the throat. It often contains active ingredients like dextromethorphan or guaifenesin, which help suppress the cough reflex or loosen mucus, respectively. Cough syrups can be found in both prescription and over-the-counter forms, and they may also include other components like antihistamines or pain relievers to address additional symptoms. When using cough syrup, it's important to follow the recommended dosage instructions on the label or as advised by a healthcare professional. Some syrups are formulated for specific age groups, such as children or adults, and may have different active ingredients. Always consult a doctor if symptoms persist or worsen.
