'''Antidotes and reversal agents''' — Antidotes; Specific reversal and detoxifying agents.

== Identification ==
* '''Therapeutic class:''' Antidotes.
* '''Pharmacologic class:''' Specific reversal and detoxifying agents.

== Pharmacology ==
* '''Mechanism of action:''' Each counteracts a specific drug, toxin, or overdose by blocking the agent, restoring a deficient substance, binding the toxin, or providing a metabolic rescue.
* '''Onset / peak / duration:''' Mostly rapid; many require repeat dosing or monitoring.
* '''Half-life / therapeutic level:''' Varies; titrate to clinical response.

== Clinical use ==
* '''Indications:''' Acetaminophen overdose (acetylcysteine, give early within 8 to 10 hours); opioid overdose (naloxone, repeat as it wears off); benzodiazepine overdose (flumazenil, caution, can cause seizures in dependent patients); warfarin (vitamin K plus fresh frozen plasma or prothrombin complex for urgent reversal); heparin (protamine sulfate); dabigatran (idarucizumab); factor Xa inhibitors (andexanet alfa); digoxin toxicity (digoxin immune Fab, DigiFab); iron overdose (deferoxamine); lead and heavy metals (EDTA, dimercaprol, succimer); cyanide and nitroprusside toxicity (hydroxocobalamin, sodium thiosulfate); organophosphate or cholinergic poisoning (atropine plus pralidoxime); magnesium toxicity (calcium gluconate); methotrexate toxicity (leucovorin, glucarpidase for severe cases); ethylene glycol or methanol poisoning (fomepizole); malignant hyperthermia (dantrolene); beta blocker overdose (glucagon); calcium channel blocker overdose (calcium, glucagon, high-dose insulin); anticholinergic toxicity (physostigmine); local anesthetic systemic toxicity (IV lipid emulsion); methemoglobinemia (methylene blue); neuromuscular blocker reversal (neostigmine for nondepolarizing, sugammadex for rocuronium and vecuronium).
* '''Usual dose, route, frequency:''' Per antidote protocol, usually IV in emergencies.
* '''Maximum dose / adjustments:''' Titrate to response; many need repeat dosing (especially naloxone).

== Safety ==
* '''Contraindications:''' Agent-specific (for example, flumazenil in chronic benzodiazepine dependence or mixed overdose with seizure risk).
* '''Black box warning:''' Andexanet alfa carries a boxed warning for thromboembolic and ischemic events, cardiac arrest, and sudden death.
* '''Interactions:''' Reversal may unmask the original condition (such as pain after naloxone or re-sedation as naloxone wears off).
* '''Pregnancy / lactation:''' Used in emergencies.
* '''High-alert:''' No.

== Adverse effects ==
* '''Common side effects:''' Withdrawal (naloxone, flumazenil), histamine release and hypotension (protamine), nausea.
* '''Serious effects to report:''' Recurrence of toxicity as the antidote wears off, allergic reaction, rebound effects.
* '''Antidote / reversal:''' Not applicable (these are the antidotes).

== Nursing process ==
* '''Assessment before administration:''' Identify the toxin or drug, severity, vital signs, time of exposure.
* '''Interventions during therapy:''' Continue monitoring because many toxins outlast their antidote; support airway and circulation; repeat dosing as indicated; involve poison control.
* '''Monitor:''' Vital signs, level of consciousness, the specific toxidrome, repeat labs.
* '''Evaluation / expected outcome:''' Reversal of toxicity with restored function.

== Patient teaching ==
* '''Patient teaching:''' Emergency therapy; teach take-home naloxone to at-risk patients and families.
* '''Notify provider if:''' Symptoms recur after improvement (the antidote may be wearing off).
* '''Administration tips:''' Match the antidote to the toxin; continue monitoring beyond the antidote's duration; consult poison control.
