"Over-the-counter" (OTC) refers to medications that can be purchased without a prescription from a doctor. These drugs are typically used to treat common ailments like headaches, colds, or allergies. Examples of OTC medications include ibuprofen, acetaminophen, and antihistamines. They are generally considered safe for public use when taken as directed. OTC products are available at pharmacies, grocery stores, and online. They are often more affordable than prescription medications, making them accessible to a wider range of people. However, it's important to read labels and follow dosage instructions to avoid potential side effects or interactions with other medications.
