Over-the-counter (OTC) drugs are medications that can be purchased without a prescription from a healthcare provider. They are commonly used to treat minor health issues such as headaches, colds, allergies, and digestive problems. OTC drugs are generally considered safe when used as directed and are available in various forms, including tablets, liquids, and creams. These medications are regulated by the U.S. Food and Drug Administration (FDA), which ensures their safety and effectiveness. Common examples of OTC drugs include ibuprofen, acetaminophen, and antihistamines. It is important for consumers to read labels and follow dosage instructions to avoid potential side effects.
