counteracts

Opposes and nullifies

Counteracts means works against something to reduce or neutralize its effect.

A medication counteracts poison by blocking its action.

One force counteracts another when they oppose each other: The pill counteracts nausea.

The word implies active opposition rather than mere prevention—something is already happening, and counteraction pushes back against it.
