DuoDote auto-injector is used for exposure to which type of agents?

• A. Treats nerve agent exposure
• B. Treats cyanide poisoning
• C. Provides analgesia
• D. Decontaminates the skin

Answer: (A)

DuoDote is designed for exposure to nerve agents, which are organophosphate compounds that block acetylcholinesterase and cause an excessive buildup of acetylcholine. The auto-injector contains atropine and pralidoxime. Atropine blocks muscarinic receptors, reducing dangerous secretions, bronchoconstriction, and other muscarinic effects. Pralidoxime reactivates acetylcholinesterase, helping reverse both muscarinic and nicotinic symptoms and improving muscle strength. This combination directly counteracts the life-threatening cholinergic crisis seen with nerve agent exposure.

It isn’t used for cyanide poisoning (which requires different antidotes), nor does it provide analgesia, nor does it decontaminate the skin.
