Over-the-counter (OTC) medications are drugs that can be purchased without a prescription. They are commonly used to treat a variety of ailments, such as headaches, colds, and allergies. OTC medications are generally considered safe when used as directed, making them accessible for self-care. These medications come in various forms, including tablets, liquids, and creams. Popular examples include acetaminophen, ibuprofen, and antihistamines. While OTC medications can be effective, it's important to read labels carefully and consult with a healthcare professional if you have any questions or concerns about their use.
