Over-the-counter (OTC) medications are designed to be safe and effective for use without the direct supervision of a healthcare provider, which is why they can be purchased without a prescription. This accessibility allows consumers to manage common ailments such as headaches, colds, and allergies on their own, making them readily available in pharmacies and retail stores.
