Adverse reaction after first dose
NCLEX-RN glossary · Pharmacological And Parenteral Therapies
Definition
An unexpected immune or physiological response occurring immediately following the initial administration of a new pharmacological agent.
Adverse reaction after first dose in plain English
Stopping the drug immediately and identifying anaphylactic cues (e.g., angioedema, stridor) to prevent irreversible injury. A frequent error is waiting for a second dose to 'verify' a reaction instead of escalating the first-dose cue as a potential allergy.
