Information shared by kidney health resources notes that this effect is more noticeable in people who are older, dehydrated, or already managing conditions like high blood pressure.

But here’s what really happens behind the scenes: the kidneys work hard to filter everything you put into your body, and NSAIDs can interfere with that delicate balance over time.

  • Groups who may want to chat with their doctor first: Anyone with existing kidney concerns, heart conditions, or who takes blood pressure medication daily.
  • Everyday signs worth noticing: Unusual swelling in the ankles or changes in how often you need to use the bathroom.

The practical takeaway? Stick to the lowest effective dose for the shortest time possible, and always stay well hydrated.

Medication 2: Acetaminophen (Commonly Known as Tylenol)

Acetaminophen is often chosen because it’s gentler on the stomach than other pain relievers. You’ll find it in countless cold, flu, and headache products.  Health professionals remain mindful about total daily intake because going over recommended limits—even accidentally—can affect the liver and, in some cases, add stress to the kidneys.
