General Toxicity Notes
Blood levels most often the best guide to therapy. Half-life may be prolonged in heart failure or with reduced hepatic blood flow.

Toxicity Notes
Extreme caution should be exercised in the use of sotalol in patients with renal failure undergoing hemodialysis. To minimize the risk of induced arrhythmia, patients initiated or re-initiated on sotalol should be placed for a minimum of 3 days (on their maintenance dose) in a facility that can provide cardiac resuscitation and continuous electrocardiographic monitoring.
