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 coughs 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. These syrups are typically taken by mouth and come in various flavors to make them more palatable, especially for children. It's important to follow the dosage instructions on the label or provided by a healthcare professional to ensure safe and effective use.
