What is pralidoxime injection?
PRALIDOXIME (Protopam®) treats poisoning by some insecticides (called organophosphates) and nerve agents, and overdoses of some medicines that treat myasthenia gravis. Generic pralidoxime injection is available. Emergency kits for injection are also available.
What should my health care professional know before I receive pralidoxime?
They need to know if you have any of these conditions:
an unusual or allergic reaction to pralidoxime, other medicines, foods, dyes, o preservatives
pregnant or trying to get pregnant
How should I use this medicine?
Pralidoxime is for injection into a muscle, under the skin, or into a vein. It is given by a health-care professional in a hospital or clinic setting. Pralidoxime is not for self-medication, except in emergency situations when it is possible that workers may be exposed to nerve agents or organophosphate insecticides. Injection kits are available for self-injection in case of emergency. Learn how and when to use the autoinjector before an emergency arises. If organophosphate poisoning occurs, atropine and pralidoxime are given as soon as possible. An atropine injection is given first and after the effects become apparent pralidoxime is given. Repeat the injections of atropine and pralidoxime after 15 minutes if symptoms continue, and again after an additional 15 minutes if symptoms persist. If symptoms of nerve agent exposure continue after the third set of injections, obtain medical help.
What if I miss a dose?
This does not apply.
What drug(s) may interact with pralidoxime?
barbiturate medicines for inducing sleep or treating seizures (convulsions)
medicines that improve muscle strength or tone for conditions like myasthenia gravis
