Summary
Salsalate is a salicylate with weak prostaglandin inhibition and may mildly blunt the natriuretic effect of spironolactone. A small increase in potassium or reduction in renal function is possible, mainly in vulnerable patients.
What this interaction means in plain words
Salsalate 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
Reduced renal prostaglandin synthesis lowers renal perfusion and sodium and potassium excretion, partially opposing spironolactone.
What to do
No routine adjustment is needed; monitor potassium, creatinine and blood pressure in patients with renal impairment or heart failure on long-term salsalate.
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?
