Amiodarone

NICE BNF Amiodarone

Monitoring

Rationale:

Both hypothyroidism and hyperthyroidism can occur (common to very common)
Hypothyroidism: Can be treated with levothyroxine - does NOT require amiodarone withdrawal
Hyperthyroidism: Decision to stop amiodarone is more complex, on per-patient basis.

Timing

Before treatment
During treatment: 6-monthly
After treatment: for several months (especially in elderly)

Rationale

Hepatotoxic medication
If severe LFT abnormalities OR clinical signs of liver disease develop ⇒ Stop amiodarone

Timing

Before treatment
During treatment: 6-monthly

Rationale:

Pulmonary toxicity: especially pulmonary fibrosis (common to very common)
Pulmonary toxicity is usually reversible if amiodarone is stopped promptly

Timing:

Before treatment (baseline)

NB - If pulmonary toxicity during treatment a repeat or CT scan should be conducted

Rationale

Normal potassium levels maximises the therapeutic benefit of amiodarone, and decreases its pro-arrhythmic risk

Timing

Before treatment: Serum potassium

Ensure ECG monitoring and available resuscitation facilities
Close LFT monitoring
