Synthesized in 1955, Pralidoxime is used as an antidote to treat poisoning by a chemical or pesticide, or by a drug used to treat a muscle disorder. Basically, it reverses muscle weakness or paralysis caused by a poison or certain drug overdose. However, this medication is not effective as an antidote for all types of pesticide poisonings. Although Pralidoxime is generally well-tolerated, dizziness, blurred vision, diplopia and impaired accommodation, headache, drowsiness, nausea, tachycardia, hyperventilation, maculopapular rash, and muscular weakness have been reported following administration of the drug. If possible, before you receive this drug, tell your doctor if you have kidney disease, or if you are allergic to any drugs. Also tell them if you are pregnant or breast-feeding. As a matter of fact, it is still not known whether Pralidoxime is harmful to an unborn baby. So, you must tell your doctor if you are pregnant. Plus, it is also not known whether this medication passes into breast milk or if it could harm a nursing baby. So, you also need to make sure any doctor caring for your pregnancy or your baby knows that you have received Pralidoxime.
