The information that you mention is within the normal variation of laboratory testing. The serum creatinine can vary from day to day and just be normal laboratory variation. I suggest that you continue to follow your doctors advice and get re-tested in three months off of ibuprofen. You should drink water if you are thirsty but I would not force water intake. Your kidneys should be able to correct themselves while you are off of ibuprofen. You should avoid all other non-steroidal anti-inflammatory drugs (NSAID’s) such as Motrin, Advil, Aleve and Naproxen.
