Summary

Conivaptan causes aquaresis, and rapid fluid loss may lead to hypovolemia and hypotension. With benazepril, hypotension and renal function decline are more likely.

What this interaction means in plain words

Benazepril and Conivaptan 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: Low

Why it happens

Vasopressin V1a/V2 antagonism causing free-water loss and volume depletion adds to ACE inhibitor hypotensive effects.

What to do

Monitor blood pressure, volume status, serum sodium and renal function during conivaptan therapy. Consider holding benazepril if hypotension or volume depletion develops.
