Block histamine-1 (H1) receptors, which causes sedation.
Do tricyclic antidepressants have anticholinergic effects?

How do tricyclic antidepressants cause anticholinergic effects?

Why do tricyclic antidepressants cause anticholinergic effects?
Why are tricyclic antidepressants so toxic in overdose?
TCAs are rapidly absorbed in the gastrointestinal tract. However, following an overdose, owing to the inherent anticholinergic effects, TCAs may decrease the gastrointestinal motility and cause delayed absorption and toxicity. Coingestion of other anticholinergic medications may cause more erratic absorption.
