Colchicine toxicity
Colchicine toxicity is rare but any intention overdose with colchicine is potentially lethal. Although resuscitation is a priority as with all toxicities, colchicine requires urgent decontamination due to the limited therapies we have once toxic serum levels develop.
Quinine toxicity
Quinine causes cinchonism (nausea, vomiting and tinnitus) in overdose but also blindness which is delayed and sometimes not noticed until the morning after the acute toxicity has resolved. Think of it as aspirin (the salicylism) that causes blindness.
Digoxin poisoning
Acute digoxin poisoning manifests with vomiting, hyperkalaemia and brady-tachyarrhythmias potentially leading to death, whereas chronic digoxin toxicity is far more insidious, still with gastrointestinal symptoms but in addition bradycardia and automaticity on the ECG.
NSAIDs toxicity
NSAIDs are generally benign in overdose unless a large amount is ingested which would take some effort. As 66% of NSAID overdoses are with ibuprofen we will use this as an example.
Sulfonylurea toxicity
Hypoglycaemia can occur at therapeutic doses especially in those who develop renal impairment. In overdose these drugs cause a profound and prolonged hypoglycaemia, usually apparent within 8 hours post ingestion of a standard preparation.
