Editing Lewisite (section)

=== Treatment ===
[[Dimercaprol|British anti-lewisite]], also called dimercaprol, is the antidote for lewisite. It can be injected to prevent systemic toxicity, but will not prevent injury to the skin, eyes, or mucous membranes. Chemically, dimercaprol binds to the arsenic in lewisite. It is [[Contraindication|contraindicated]] in those with [[Peanut allergy|peanut allergies]] as it is usually formulated in peanut oil.<ref name=":0"/>

Other treatment for lewisite exposure is primarily supportive. First aid of lewisite exposure consists of [[decontamination]] and [[Therapeutic irrigation|irrigation]] of any areas that have been exposed. Other measures can be used as necessary, such as [[airway management]], [[Mechanical ventilation|assisted ventilation]], and [[Monitoring (medicine)|monitoring of vital signs]]. In an advanced care setting, supportive care can include fluid and electrolyte replacement. Because the tube may injure or perforate the esophagus, [[gastric lavage]] is contraindicated.<ref name=":0"/>
