Dose & frequency: NSAIDS (Ibuprofen, Naproxen, Ketoprofen) can damage the kidneys if they are taken in too high of a dosage, too frequently or in a setting where the patient is dehydrated. You should drink plenty of fluids and avoid becoming dehydrated when you use these medicines. Ibuprofen (400mg every 6-8hrs), Naproxen (220mg every 8-12hrs) See https://www.getreliefresponsibly.com/use-pain-medicine-safely.

NSAID : The risk factors from NSAIDs (ibuprofen, naproxen and others) related kidney injury are determined by factors such as age, amount of dose, and time of NSAIDs, underlying health, or disease. How does this apply to your dose..this is best answered by doing a lab test to see how your kidney function is.
