Pralidoxime (injection route)

Protopam Chloride

Pralidoxime injection is used together with another medicine called atropine to treat poisoning caused by organic phosphorus pesticides (e.g., diazinon, malathion, mevinphos, parathion, and sarin) and by organophosphate chemicals (“nerve gases”) used in chemical warfare. Pralidoxime injection is also used to treat overdose of medicines (e.g., ambenonium, neostigmine, pyridostigmine), that are used to treat myasthenia gravis.
