Prescription Medication from WikiPedia:

A prescription drug is a licensed medicine that is regulated by legislation to require a prescription before it can be obtained. The term is used to distinguish it from over-the-counter drugs which can be obtained without a prescription. Different jurisdictions have different definitions of what constitutes a prescription drug.

Dispensation of prescription drugs often includes a monograph (in Europe, a Patient Information Leaflet or PIL) that gives detailed information about the drug.

In the United States, the Federal Food, Drug, and Cosmetic Act defines what requires a prescription. Prescription drugs are generally authorized by veterinarians, dentists, optometrists, and medical practitioners. It is generally required that an MD, DO, PA, OD, DPM, DVM, DDS, or DMD write the prescription; basic-level registered nurses, medical assistants, clinical nurse specialists, nurse anesthetists, and nurse midwives, emergency medical technicians, psychologists, and social workers as examples, do not have the authority to prescribe drugs.
