    Summary : In the U.S., the government's Food and Drug Administration (FDA) must approve any drug before it can be sold. This is true whether it's a prescription or an over-the-counter drug. The FDA evaluates the safety of a drug by looking at       - Side effects    - How it's manufactured    - Results of animal testing and clinical trials       The FDA also monitors a drug's safety after approval.
