📚 Amitriptyline — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Amitriptyline is a tricyclic antidepressant (TCA) used for depression and, at lower doses, for neuropathic pain, migraine prophylaxis, and insomnia. Its strong anticholinergic and cardiac effects make overdose dangerous and limit its use in older adults. TCAs are highly lethal in overdose, which is a key safety concern given depressed patients. Memory aid: TCAs cause the anticholinergic 'can't see, can't pee, can't spit, can't poop.'
Causes orthostatic hypotension and sedation; can prolong QT and cause dysrhythmias.
Overdose is potentially lethal due to cardiotoxicity and arrhythmias; only small quantities should be dispensed.
Therapeutic effect takes 2-4 weeks; carries the antidepressant suicide black box warning.
Avoided in older adults (Beers criteria) due to falls, confusion, and cardiac risk.
Can cause serotonin syndrome with MAOIs and other serotonergic drugs.

Nursing priorities
What to do, in order
Assess suicide risk and limit the quantity dispensed because of overdose lethality.
Monitor for orthostatic hypotension and fall risk; teach slow position changes.
Manage anticholinergic effects (fluids/fiber for constipation, sugar-free hard candy for dry mouth).
Obtain baseline ECG in patients with cardiac history; monitor heart rhythm.
Teach the 2-4 week delay and adherence.

Patient teaching
What patients must know
Expect 2-4 weeks for full effect; do not stop abruptly.
Rise slowly to prevent dizziness and falls.
Manage dry mouth and constipation with fluids, fiber, and sugar-free candy.
Report suicidal thoughts; keep medication secured given overdose danger.

What do I need to know about Amitriptyline for the NCLEX?
Strong anticholinergic effects: dry mouth, blurred vision, constipation, urinary retention, confusion. Causes orthostatic hypotension and sedation; can prolong QT and cause dysrhythmias. Overdose is potentially lethal due to cardiotoxicity and arrhythmias; only small quantities should be dispensed. Therapeutic effect takes 2-4 weeks; carries the antidepressant suicide black box warning.
