OTC medications, or over-the-counter medications, are drugs that you can buy without a prescription from a doctor. They are commonly used to treat minor health issues like headaches, colds, allergies, and digestive problems. Because they are easily accessible, many people rely on them for quick relief from everyday ailments. These medications are generally considered safe when used as directed, but it's important to read the labels carefully. Some OTC medications can interact with other drugs or have side effects. Always consult a healthcare professional if you have questions or if symptoms persist.
