A low-potassium diet containing 2 g of potassium is recommended so as to minimize potassium intake in patients at risk for hyperkalemia. In particular, potassium intake must be closely monitored (and possibly restricted) in patients with renal failure.

No restrictions on activity are necessary unless continuous monitoring for cardiotoxicity is required.
