Before any drug can be sold in the United States, it must be approved by the U.S. Food and Drug Administration (FDA). This is true whether it's a prescription or an over-the-counter drug. The FDA evaluates both the effectiveness and safety of a drug by looking at: How animal testing and human clinical trials affect the condition the drug is treating If any side effects occur How it's manufactured What the labeling says The FDA also monitors a drug's safety after approval. Health care providers and patients can report drug side effects through the FDA's MedWatch website . For you, drug safety means buying online only from licensed pharmacies located in the United States. It also means knowing how to take your medicines correctly .
