Which side effect described as 'cant spit' is associated with tricyclic antidepressants?

• A. Photophobia/blurred vision
• B. Urinary retention
• C. Dry mouth
• D. Constipation

Answer: (C)

Tricyclic antidepressants can cause anticholinergic effects by blocking muscarinic receptors, which reduces saliva production. That decrease in saliva leads to a dry mouth, the familiar phrase "can’t spit." So the description points to dry mouth as the side effect. The other options—photophobia/blurred vision, urinary retention, and constipation—are also possible with anticholinergic activity, but they don’t match the specific symptom described.
