primary effects
Direct immediate outcomes
Primary effects are the immediate, direct consequences of an action, event, or substance—what happens first, before any chain reactions set in.
In pharmacology, primary effects are a drug's intended therapeutic actions, distinguished from side effects.
In disaster response, primary effects are the initial damage: The earthquake's primary effects included collapsed buildings and ruptured gas lines.
Secondary effects follow from these.
