What side effects may occur with tricyclic antidepressants?

Tricyclic antidepressants (TCAs) can lead to a range of side effects due to their anticholinergic properties, which often result in symptoms such as dryness of the mouth and blurred vision. These medications work by affecting the balance of neurotransmitters in the brain and also block the action of acetylcholine, a neurotransmitter involved in several bodily functions. This blockage can lead to a reduction in saliva production, causing dryness in the mouth, and can also affect the eyes, leading to blurred vision.

While other potential side effects may include weight gain or sleep disturbances, the specific symptoms of dryness of the mouth and blurred vision are well-documented and characteristic of the TCA class, making this choice particularly relevant in understanding the side effects associated with these medications.
