Summary

Non-acetylsalicylate salicylates at anti-inflammatory doses may blunt the antihypertensive effect of fosinopril. In volume-depleted, elderly or renally impaired patients they may also worsen renal function.

What this interaction means in plain words

Fosinopril and Salicylates can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Moderate

Why it happens

Inhibition of prostaglandin synthesis reduces vasodilation and renal sodium excretion, opposing ACE inhibitor effects.

What to do

Monitor blood pressure, creatinine and potassium with regular anti-inflammatory salicylate use. Prefer paracetamol where appropriate.
