Over-the-counter (OTC) medications are non-prescription drugs available for purchase without a doctor’s prescription. They treat common ailments like headaches, colds, allergies, and minor pains. OTC medications come in various forms, including tablets, capsules, liquids, and creams, and typically contain active ingredients such as acetaminophen, ibuprofen, or antihistamines. While generally safe when used as directed, it’s crucial to read labels carefully and follow dosing instructions. Consulting a healthcare professional before starting any new medication is advisable, especially for those with underlying health conditions.
