Adverse drug reactions are always ______ and must be reported and documented

An ______ reaction is an immune response that occurs after prior sensitization to a drug

Physical ______ develops when the body has adapted to drug exposure and will result in withdrawal symptoms if drug use is stopped

Drug toxicity occurs when drug levels exceed the therapeutic ______
