Cough medicine is a type of medication designed to relieve coughing. It can be classified into two main categories: antitussives, which suppress the cough reflex, and expectorants, which help loosen mucus in the airways. These medicines are commonly used to treat coughs caused by colds, flu, or other respiratory conditions. Cough medicines come in various forms, including syrups, tablets, and lozenges. Some may contain ingredients like dextromethorphan or guaifenesin, which target specific symptoms. It's important to follow dosage instructions and consult a healthcare professional if symptoms persist or worsen.
