📚 Amiodarone — 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.
Amiodarone is a class III antiarrhythmic used for life-threatening ventricular arrhythmias and atrial fibrillation. It prolongs the action potential and slows conduction. Key principle: it has serious long-term toxicities, most importantly pulmonary fibrosis, and affects the thyroid, liver, and eyes.
🔑
Key points
Understand these first
It can cause pulmonary toxicity and fibrosis, the most serious long-term adverse effect.
It affects the thyroid and can cause either hypothyroidism or hyperthyroidism (it contains iodine).
It can cause blue-gray skin discoloration, corneal deposits, photosensitivity, and liver toxicity.
It prolongs the QT interval and can cause bradycardia and hypotension.
It has a very long half-life, so effects and toxicities persist for weeks after stopping.
✅
Nursing priorities
What to do, in order
Monitor cardiac rhythm, heart rate, blood pressure, and QT interval.
Assess respiratory status, including a baseline chest x-ray and lung sounds, for pulmonary toxicity.
Monitor thyroid function and liver enzymes during therapy.
Use an in-line filter and infusion pump for IV administration.
Assess for visual changes and report new dyspnea or cough.
🚩
Red flags — report now
Escalate immediately
Report new cough, dyspnea, or chest pain (pulmonary toxicity).
Report severe bradycardia, hypotension, or prolonged QT.
Report vision changes and signs of thyroid or liver dysfunction.
🧪
Labs & values
Numbers to know
TSH 0.4-4.0 mIU/L
AST 10-40 units/L and ALT 7-56 units/L (liver function)
Monitor QT interval on ECG
🗣️
Patient teaching
What patients must know
Wear sunscreen and protective clothing because of photosensitivity.
Report shortness of breath, cough, vision changes, or unusual fatigue.
Keep all lab and pulmonary follow-up appointments.
❓ Amiodarone: NCLEX FAQs
