@donasmrs-- Ibuprofen can cause liver issues in those who take high doses regularly or who drink alcohol or have diabetes. Of course it will also effect those who already have liver disease. These factors increase the risk that the liver will be affected.
But occasional use of ibuprofen by a completely healthy person who doesn't drink too much alcohol or use other medication is not going to do anything to the liver.
Ibuprofen is actually much safer for the liver than say, acetaminophen. Doctors also prefer their patients with chronic pain to use ibuprofen vs acetaminophen.
