• TCAs (Amitriptyline): Chronic depression with insomnia or pain symptoms; second-line due to side effects.
• Buspirone: Adjunct for anxiety without sedation or dependency risk.

Key Points

• Antidepressants take 2–6 weeks to show effect.
• Start low dose, titrate gradually.
• Monitor side effects: especially cardiovascular for TCAs, bleeding for SSRIs.
