Summary
Non-acetylated salicylates have weak NSAID-like effects on renal prostaglandins and may slightly reduce the diuretic and antihypertensive effect of spironolactone. Potassium retention is possible but usually small at ordinary doses.
What this interaction means in plain words
Salicylates and Spironolactone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Inhibition of renal prostaglandin synthesis can reduce renal blood flow, sodium excretion and potassium excretion, modestly opposing spironolactone effects.
What to do
Usually no change is required; check potassium and renal function if high-dose salicylates are used long term, especially in older or renally impaired patients.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
