Amitriptyline is a tricyclic antidepressant that is often used for neuropathic pain management. One of its significant side effects is anticholinergic effects. These effects can include dry mouth, constipation, urinary retention, blurred vision, and confusion, particularly in older adults. The presence of these anticholinergic side effects can limit its use as a first-line treatment option because they may impact patients' quality of life and lead to potential complications, especially in populations vulnerable to such side effects, such as the elderly.

While cardiovascular instability, cognitive impairment, and gastrointestinal upset are potential side effects of amitriptyline, anticholinergic effects are particularly noteworthy because they are broad in impact and can cause significant discomfort or complicate existing health conditions. This makes clinicians cautious when prescribing amitriptyline, particularly for patients who may already be dealing with other medical issues.
