Common Drugs and Their Antidote (Part 2)

A poison or toxin can be neutralized with antidotes. The antidotes work by either preventing the absorption of the toxin, by binding and neutralizing it, reducing its effects in the body, or by preventing the conversion of more toxic substances into the toxin.

You can take this quiz to learn more about the most common poisonings from drugs and their antidotes.

  • Question of

    The antidote for paracetamol poisoning.

    • Acetylcysteine
    • Oxygen
    • Digoxin immune fab
    • Leucovorin

    Correct Wrong

    Acetylcysteine, or N-acetylcysteine (NAC), a drug that is used to treat paracetamol (acetaminophen) overdose. As a liver protectant, acetylcysteine may help to avoid or lessen liver damage caused by excessive use of acetaminophen.

  • Question of

    The antidote for calcium channel blockers toxicity.

    • Calcium chloride
    • Acetylcysteine
    • Flumazenil
    • Atropine

    Correct Wrong

    Calcium chloride is an antidote to the toxicity of calcium channel blockers. Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2.

  • Question of

    The antidote for thallium poisoning

    • Prussian blue
    • Digoxin immune fab
    • Leucovorin
    • Ethanol and fomepizole

    Correct Wrong

    Radioactive cesium and thallium can be removed from people's bodies with Prussian blue. In the intestines, Prussian blue traps radioactive cesium and thallium to prevent them from being absorbed by the body. The radioactive materials pass through the intestines and exit the body (excrete). This helps limit the amount of radiation the body is exposed to by getting these materials out of the body.

  • Question of

    The antidote for warfarin poisoning.

    • Phytomenadione (Vitamin K)
    • Deferoxamine
    • Leucovorin
    • Pralidoxime

    Correct Wrong

    Bleeding is the most common side effect of warfarin use. Vitamin K, prothrombin complex concentrate (PCC), or fresh frozen plasma (FFP) can reverse the effects of warfarin.

  • Question of

    The antidote for benzodiazepines poisoning.

    • Flumazenil
    • Oxygen
    • Pyridoxine (Vitamin B6)
    • Glucagon

    Correct Wrong

    In patients who have taken an intentional benzodiazepine overdose or undergoing anesthesia, flumazenil is useful in helping to reverse sedation and respiratory depression caused by benzodiazepines.

  • Question of

    The antidote for digitalis toxicity.

    • Digoxin immune fab
    • Glucagon
    • Calcium chloride
    • Octreotide

    Correct Wrong

    Digoxin immune fab, derived from anti-digoxin immunoglobulin fragments, is the treatment of choice for digoxin toxicity. Digibind (GlaxoSmithKline) and DigiFab (BTG plc) are its brand names.

  • Question of

    The antidote for magnesium toxicity.

    • Calcium gluconate
    • Flumazenil
    • Sodium bicarbonate
    • Ethanol and fomepizole

    Correct Wrong

    Calcium gluconate is a mineral supplement and medicine. It is injected into a vein to treat low blood calcium, high blood potassium, and magnesium toxicity. When magnesium toxicity is severe, it is treated with intravenous administration of calcium gluconate 10% (10-20 mL) and support for the circulatory and respiratory systems. The use of calcium gluconate may reverse many of the effects of magnesium, including respiratory depression.

  • Question of

    The antidote for organophosphate poisoning.

    • Pralidoxime
    • Sodium bicarbonate
    • Activated charcoal
    • Sodium bicarbonate

    Correct Wrong

    Pralidoxime belongs to a family of compounds known as oximes, which bind to organophosphate-inactivated acetylcholinesterase. It is used in conjunction with either diazepam or midazolam in treating organophosphate poisoning.

  • Question of

    The antidote for heavy metal poisoning.

    • Dimercaprol
    • Ethanol and fomepizole
    • Flumazenil
    • Prussian blue

    Correct Wrong

    Dimercaprol, also known as British anti-Lewisite (BAL), is a medication used to treat acute poisoning by heavy metals such as arsenic, mercury, gold, and lead.

  • Question of

    The antidote for beta-blockers, calcium channel blockers, and hypoglycemic toxicity.

    • Glucagon
    • Idarucizumab
    • Pralidoxime
    • Acetylcysteine

    Correct Wrong

    Glucagon is the antidote for beta-blockers, calcium channel blockers, and hypoglycemic toxicity. As the main catabolic hormone in the body, it raises the level of glucose and fatty acids in the bloodstream.
