According to the FDA, oxygen is a what?

• A. Over-the-counter drug
• B. Prescription drug
• C. Medical device
• D. Dietary supplement

Answer: (B)

Oxygen used for medical therapy is regulated by the FDA as a prescription drug. When prescribed, it comes with a specific flow rate and FiO2, and the patient’s oxygenation is monitored, which means a clinician’s order is required. This pharmacologic, dose-specific use is why it’s treated as a prescription drug rather than an over-the-counter product, a dietary supplement, or a standalone medical device. The prescription requirement ensures proper dosing, safety, and ongoing assessment of therapy.
