NSAIDs (Non-Steroidal Anti-Inflammatory Drugs):
-
Examples: Ibuprofen (Advil, Motrin), Naproxen (Aleve)
-
How they work: Reduce inflammation, pain, and fever by blocking certain enzymes (COX-1 and COX-2).
-
Kidney risk: Prolonged use can reduce blood flow to the kidneys, causing acute kidney injury or chronic kidney disease, especially in people with pre-existing kidney problems, high blood pressure, or diabetes.
-
-
Acetaminophen (Paracetamol, Tylenol):
-
How it works: Reduces pain and fever but does not reduce inflammation.
-
Kidney risk: While generally safer than NSAIDs for the kidneys when taken occasionally, long-term or high-dose use may still contribute to kidney damage. Combined use with alcohol or other medications increases the risk.
-
Who Is at Higher Risk?
Certain groups are more vulnerable to kidney damage from painkillers:
-
People with existing kidney disease
-
Those with high blood pressure or diabetes
-
Elderly individuals whose kidney function naturally declines with age
-
People who take multiple medications that affect the kidneys
-
Individuals who use painkillers frequently for chronic pain
