What is the antidote for iron poisoning?

Deferoxamine is the antidote specifically indicated for iron poisoning because it is a chelating agent that binds to free iron in the bloodstream, facilitating its excretion from the body via the kidneys. In cases of iron overdose, iron can cause significant tissue damage and lead to severe toxicity. Deferoxamine works by forming a stable complex with iron, which helps to reduce the iron load and mitigate the harmful effects associated with excess iron, preventing organ damage.

Activated charcoal is typically used to adsorb various toxins and prevent their absorption if administered soon after ingestion, but it is not effective for iron, as it does not bind well to iron compounds. Calcium gluconate is used as an antidote for magnesium or calcium channel blocker overdoses but is not relevant in cases of iron poisoning. N-acetylcysteine is primarily used for acetaminophen toxicity and does not address iron poisoning.
