The symptoms of an anticholinergic toxidrome include blurred vision, choreoathetosis, coma, decreased bowel sounds, delirium, dry skin, fever, flushing, hallucinations, ileus, memory loss, mydriasis (dilated pupils), myoclonus, psychosis, seizures, and urinary retention. Complications include hypertension, hyperthermia, and tachycardia. Substances that may cause this toxidrome include antihistamines, atropine, benztropine, datura, tricyclic antidepressants, and scopolamine.

Due to the characteristic appearance and behavior of patients with this toxidrome, they are colloquially described as "Hot as a Hare, Dry as a Bone, Red as a Beet, Mad as a Hatter, Blind as a Bat".
