Summary
Fenoprofen can blunt the antihypertensive effect of olmesartan and hydrochlorothiazide. The NSAID, ARB and diuretic combination can impair kidney function and raise potassium, especially in the elderly or when dehydrated.
What this interaction means in plain words
Fenoprofen and Hydrochlorothiazide-olmesartan can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Why it happens
NSAID inhibition of vasodilatory renal prostaglandins reduces renal perfusion and sodium excretion, compounding ARB effects.
What to do
Use paracetamol or another non-NSAID option where possible. If an NSAID is needed, use the lowest dose briefly and monitor blood pressure, creatinine and potassium.
