Anticholinergic Toxidrome
Introduction
Anticholinergic toxicity, to varying degrees, is seen relatively frequently in toxicology patients. The main clinical challenge is the safe management of the delirium which occurs due to ventra anticholinergic effects.
The mainstay of treatment is supportive care, whilst time is allowed for the toxicity to resolve; however, patients frequently require sedation and antidotal therapy with physostigmine/rivastigmine for both their own and staff safety.
