What is the antidote for iron overdose?

  1. Vitamin K

  2. Naloxone

  3. Deferoxamine

  4. Acetylcysteine

The correct answer is: Deferoxamine

The other options listed may confuse some people, as vitamin K is the antidote for an overdose of blood thinning medications, naloxone is the antidote for opioid overdose, and acetylcysteine is the antidote for acetaminophen overdose. Only deferoxamine is specifically used as an antidote for iron overdose. It works by binding to the excess iron in the body and allowing it to be excreted through urine.
