Mushroom Poisoning
Early muscarinic symptoms
Certain mushrooms contain toxins that stimulate muscarinic cholinergic receptors, thus mimicking the effects of acetylcholine on these receptors (the toxins do not stimulate nicotinic cholinergic receptors). Mushrooms that cause early muscarinic symptoms include members of theInocybeandClitocybegenera. Symptoms may include the SLUDGE syndrome (see table Common Toxic Syndromes ), including miosis, bronchorrhea, bradycardia, diaphoresis, wheezing, and cramps. Symptoms are usually mild, begin within 30 minutes, and resolve within 12 hours. Atropinemay be given to treat severe muscarinic symptoms (eg, wheezing, bradycardia).
