Generic Prescription Drug
Generic prescription drugs are prescription drugs that have the same active-ingredient formula as a brand-name prescription drug. They are not patented, and usually cost less than brand-name prescription drugs. The U.S. Food and Drug Administration (FDA) states that generic prescription drugs are the same as brand name prescription drugs in terms of quality, safety, strength, the way in which they work, and the way they are used.
The patient chose the generic prescription drug option because it was less expensive and he believed it would work the same as a brand name prescription drug.
