Can you take ibuprofen while on lisinopril?
No, it's generally not recommended to take ibuprofen (an NSAID like Advil or Motrin) with lisinopril (an ACE inhibitor for high blood pressure). Combining them can reduce lisinopril's blood pressure-lowering effect and raise risks of kidney damage, especially in people with dehydration, kidney issues, or heart failure.[1][2]
Why does this combination cause problems?
Ibuprofen blocks prostaglandins that help keep kidney blood vessels open. Lisinopril also affects kidney blood flow by relaxing vessels. Together, they can drop kidney function sharply, leading to acute kidney injury. Studies show this risk jumps 30-80% with regular NSAID use in ACE inhibitor patients.[1][3]
What are safer alternatives to ibuprofen?
For pain or inflammation, try acetaminophen (Tylenol) up to 3,000-4,000 mg daily—it's easier on kidneys and doesn't interfere with lisinopril.[2] Other options include topical NSAIDs (like diclofenac gel) or non-drug approaches like heat/ice. Short-term, low-dose ibuprofen (under 400 mg) might be okay occasionally, but only under doctor guidance.[1]
When is the risk highest?
Avoid the combo if you have chronic kidney disease, diabetes, age over 65, low blood volume, or take diuretics. Even one dose can trigger issues in vulnerable people; monitor for swelling, less urine, or fatigue.[3][4]
What should you do if you've already taken both?
Check with your doctor or pharmacist right away. They may order kidney function tests (creatinine, GFR). Stop ibuprofen and stay hydrated.[2]
How long to wait between doses?
Space them at least 24-48 hours if possible, but don't rely on timing—consult a professional first.[1]
