From the Guidelines
Yes, amiodarone can cause tiredness or fatigue as a side effect. This medication, which is used to treat irregular heart rhythms (arrhythmias), commonly causes fatigue in many patients who take it. The tiredness typically develops gradually and may become more noticeable with continued use. This side effect occurs because amiodarone affects multiple body systems, including thyroid function and lung tissue, and has a very long half-life (staying in the body for weeks to months) 1.
Common Side Effects of Amiodarone
Some of the common side effects of amiodarone include:
- Sensitivity to sunlight
- Bluish skin discoloration
- Thyroid problems
- Potential lung or liver complications These side effects should all be monitored regularly by a healthcare provider.
Management of Fatigue
Patients taking amiodarone should not stop the medication if experiencing fatigue but should discuss this symptom with their healthcare provider. The fatigue may be managed by adjusting the dosage or timing of medication, though some degree of tiredness might persist as long as the medication is needed 1.
Importance of Monitoring
Regular monitoring of patients taking amiodarone is crucial to manage potential side effects and ensure the safe use of the medication. This includes monitoring the ECG and serum K+ and Mg2+ levels, as well as being aware of the potential for proarrhythmia in patients with structural heart disease 1.

From the Research
Amiodarone Side Effects
- Amiodarone is known to have several side effects, including thyroid abnormalities, pulmonary fibrosis, and transaminitis, for which routine monitoring is recommended 2.
- However, the provided studies do not specifically mention tiredness as a side effect of amiodarone.
- Amiodarone can interact with several medications, such as warfarin, simvastatin, and atorvastatin, and many HIV antiretroviral medications 2.
Amiodarone Usage and Effectiveness
- Amiodarone is the most commonly prescribed antiarrhythmic drug for atrial fibrillation, followed by sotalol and dofetilide 3.
- Amiodarone has been shown to be effective for rhythm control of atrial fibrillation, with a lower risk of AF recurrence compared to other antiarrhythmic drugs 4.
- Amiodarone may increase defibrillation threshold, which can affect the function of implantable cardioverter-defibrillators (ICDs) 5.
Amiodarone and Cardiac Risks
- Amiodarone can cause QT prolongation, which can lead to life-threatening arrhythmias such as torsade de pointes 6.
- The risk of QT prolongation is influenced by factors such as dosage, coexisting medical conditions, electrolyte imbalances, and other risk factors 6.
- Close monitoring of the QT interval is recommended for patients receiving amiodarone therapy, and consideration should be given to patient-specific risk factors for Long QT syndrome 6.
