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. Poisoning with these chemicals or medicines causes your muscles, including the muscles that help you breathe, to become weak. Pralidoxime is used to help you get back strength in your muscles.

This medicine is to be given only by or under the direct supervision of a doctor or trained military personnel.
