Why are some medications prescription-only, while others are over the counter (OTC)? Are the OTC equivalents of prescription medications?

Nicole and Jez discuss the classification criteria for medications, and why OTC medications are not always the best choice instead of a vet visit or a prescription.

Dr Nicole Su is a veterinarian, Jez Watts is a comedian-biotechnologist, and together they discuss commonly misunderstood topics in the pet and vet world. They live with three rabbits who are their children.
