OTC vs Prescription Medicines: Key Differences Explained

What Are OTC Medicines?

Over-the-counter (OTC) medicines are medications that have been deemed safe and effective for use without a doctor's prescription. The FDA reviews and approves OTC medications, ensuring they are appropriate for self-treatment of conditions that consumers can identify themselves.

What Are Prescription Medicines?

Prescription medicines require a valid prescription from a licensed healthcare provider because they: carry higher risks that require medical supervision, treat conditions that need professional diagnosis, require specific dosing based on individual factors, or have significant drug interaction potential.

How Are Medicines Classified?

Drug classification involves rigorous evaluation of safety profiles, efficacy data, and the complexity of conditions being treated. Some medicines start as prescription-only and later move to OTC status as safety data accumulates.

Making Safe Choices

• Always read and follow OTC medicine labels completely
• Never take prescription medicines without a valid prescription
• Inform all your healthcare providers about all medications you take
• Ask your pharmacist if you have questions about any medication
