Ibuprofen can reduce the blood pressure-lowering effect of lisinopril and may increase the risk of kidney damage. Regular use of ibuprofen with lisinopril can undermine blood pressure control and, in some cases, lead to acute kidney injury, especially in patients who are dehydrated.
How This Interaction Works (Mechanism)
NSAIDs like ibuprofen inhibit prostaglandin synthesis in the kidneys. Prostaglandins help maintain renal blood flow, especially when the renin-angiotensin system is already blocked by an ACE inhibitor like lisinopril. Without prostaglandin-mediated vasodilation, renal perfusion drops, reducing the kidney's ability to filter blood and regulate blood pressure. This creates a dual hit on kidney function.

Avoid regular or prolonged use of ibuprofen while taking lisinopril. Occasional short-term use (1 to 2 days) at the lowest effective dose is generally acceptable for most patients. Consider acetaminophen as an alternative for pain relief. Stay well hydrated. If you must use ibuprofen regularly, your doctor should monitor your blood pressure and kidney function closely.
