Overview of Adverse Drug Reactions
Identification and reporting of adverse drug reactions
Many adverse drug reactions are identified when a drug is being tested before it is submitted to the Food and Drug Administration (FDA) for approval. Other adverse drug reactions, typically those that are uncommon, are not detected until the medication has been on the market long enough to be used by a large number of people. Thus, health care providers are required to report suspected adverse drug reactions to the FDA.
