Can You Take lisinopril and spironolactone Together?
Evidence-based clinical pharmacological assessment, adverse synergy evaluation, and administration separation protocols.
Co-administering lisinopril and spironolactone has documented pharmacodynamic or pharmacokinetic antagonism capable of triggering acute clinical harm. Do not combine without explicit specialist oversight.
Clinical Mechanism & Evidence Details
Suppression of aldosterone causes renal potassium retention; potassium salt substitutes can trigger sudden, life-threatening hyperkalemic cardiac arrest.
Alcohol may enhance gastrointestinal irritation, trigger orthostatic hypotension, or alter drug absorption kinetics.
Tannins, polyphenols, and calcium form unabsorbable iron complexes, dropping non-heme iron absorption by 60-80%.
Talk to your doctor before using salt substitutes containing potassium. If your doctor prescribes a low-salt or low-sodium diet, follow these directions carefully.
