Prior to advising an increase in potassium intake, the following types of patients, who are at high risk of developing hyperkalemia, should be assessed for suitability, and monitored closely:

• Patients taking renin-angiotensin-aldosterone inhibitors
• Patients on other drugs that can cause hyperkalemia (e.g., trimethoprim and sulfamethoxazole, amiloride, triamterene)
• Chronic kidney disease (glomerular filtration rate <60 mL/min/1.73m2)
• Baseline serum potassium >4.5 mmol/L
