Enalapril lowers aldosterone and potassium excretion, so potassium supplements can lead to hyperkalemia. Patients with renal impairment or heart failure are most at risk.
What this interaction means in plain words
Enalapril and Potassium bicarbonate can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Enalapril belongs to Cardiovascular; Potassium bicarbonate belongs to Gastrointestinal Tract.
Why it happens

What to do
Monitor serum potassium and renal function within days of starting, and regularly thereafter; use potassium only when clearly needed.
