How to treat anticholinergic toxicity?

Supportive care is usually all that is required for the treatment of anticholinergic toxicity. The most difficult therapeutic challenge is treating the agitation that can be severe in patients with anticholinergic toxicity. Benzodiazepines administered intravenously should be the first-line therapy for agitation. This may require large doses but is necessary to avoid making symptoms such as hyperthermia and rhabdomyolysis worse. Physostigmine may be indicated in severe cases refractory to benzodiazepines.[26]  IV fluids should be administered in the case of hypotension or if rhabdomyolysis is suspected. Cooling measures should be initiated if significant hyperthermia is present.[27]  Activated charcoal should be considered if the ingestion occurred within one hour before the patient presents. However, administration somewhat outside this window may be appropriate, as anticholinergics decrease gastrointestinal motility. [28][29]If wide-complex dysrhythmias develop, IV sodium bicarbonate should be administered. [25][30]
