aspirin + torsemide
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Salicylates/NSAIDs may blunt the natriuretic and antihypertensive effect of loop diuretics and increase risk of renal dysfunction, especially at higher aspirin doses.
Mechanism of action
NSAID-mediated inhibition of renal prostaglandin synthesis reduces renal blood flow and antagonizes loop diuretic natriuresis.
Clinical management
Avoid chronic/high-dose aspirin if possible; if needed, use lowest effective dose. Monitor BP, weight/edema, and renal function (SCr/BUN). Adjust diuretic dose based on response.
