If the bleeding continues, a second dose can be given at 0.5 mg per 100 U of anti–factor Xa activity.35, P. Gómez-Ramírez, A.J. An antidote must act fast — before the poison does irreversible damage — to be effective and save lives. These counteract or neutralize the effect of a poison. BAL is given by intramuscular (IM) injection as an antidote for whole-body (systemic) health effects of lewisite but has no effect on local lesions of the skin, eyes, or airways.

Victims should also be admitted if they have respiratory complaints or underlying lung disease.2, Any solid powder or smoke particles should be gently brushed from the skin. Intramuscular injection may cause local pain and erythema. Antidotes are applied before absorption of the poison (local-acting antidotes) or after its entry into the bloodstream (resorptive antidotes). Seizures should be controlled first. During chronic stages that confirm diabetes diagnosis, patients can present with at least two other common occurrences concerning glycemic levels. In clinical studies at therapeutic levels, anticoagulation parameters generally return to baseline within 2 to 4 hours after discontinuation of the drug.

Patients should understand proper timing, such as how to predict peak action of insulin when indicated snacks, meals, herbs, and nutritional supplements can be integrated with oral or injected pharmaceutical drugs. Antidotes of this type include unitiol, the British Anti-Lewisite (BAL) and the similar Hungarian dikaptol, Czechoslovak dimerkaprol, and German (GDR) Dithio-glycerine, which counteract compounds of mercury, chrome, arsenic, and other metals (except lead), whose effect is due mainly to the presence in them of molecules of the sulf-hydryl (SH) groups; oximes, which reactivate the enzyme cholinesterase, which is blocked in cases of organic phosphorous poisoning; preparations of ethylenediaminetetra-acetic acid (EDTA), which forms complexes with the salts of heavy metals that are eliminated relatively quickly in the urine; and several others. The U.S. Scombroid-related symptoms can be alleviated with epinephrine, anti-H1 histamine blockers, adrenergic β-2 agonist bronchodilators, and fluid replacement. In reviewing their hospital's experience with continuous infusions of deferoxamine in acute iron intoxication, they noted that no patients developed pulmonary complications when treated for 24 hours or less, and recommended that deferoxamine infusions be limited to 24 hours in duration. A combination of penicillin (300,000 to 1,000,000 units/kg per day, or 250 mg/kg per day intravenously) and silibinin (20-50 mg/kg per day intravenously) has been used as a specific antidote in those with evidence of liver injury due to Amanita poisoning.133,134 These agents are hypothesized to interrupt the enterohepatic circulation of toxins and also to compete at the hepatocyte membrane for transmembrane transport.56 Because of the rarity of this cause of ALF, the benefits of this regimen remain unproven. NAC remains the treatment of choice for APAP overdose (Table 20-16), and in theory may protect the liver from other toxins that cause hepatotoxicity by generating free radicals, such as carbon tetrachloride or trichlorethylene.120,121 The administration of NAC for APAP overdose replenishes glutathione, thereby detoxifying NAPQI.122 In addition, NAC improves oxygen delivery and consumption in ALF.123 On presentation the risk of APAP hepatotoxicity in an individual can be estimated by a nomogram plot of the initial plasma APAP concentration versus the time after ingestion (Fig.
