How long can you take ibuprofen until you really start damaging your liver and kidney?

hi ibuprofen in time will damage the liver and you could end up with gastritis the way i did which affects the lining of your stomach. that was the worst for me. i take it only when absolutely necessary. there are other alternatives that coat the stomach first and has less side effects. i would recommend boswellia and white willow for natural pain relievers. they are just like aspirin and ibuprofen. apply some natural pain reliever called tei fu lotion. this is used to treat pain topically.
