<s>[INST] Yes my dad is 74 with past kidney problems and they just did 2 procedures on him with dye . it is 4 days after any procedure and his creat level is still 2.6 . he has a kidney infection also. he has been drinking water and cranberry juice and they have been using antibiotics on him. question is there any thing else that can be done to bring the level down? [/INST] Thank you for using Chat Doctor Your question does not indicate what his pre-existing kidney function was, and I am making the presumption that the dye used was an Dominated radio contrast such as used for a heart catheterization or CAT scan and not a nuclear isotope or MRI contrast. There are a few things which can be done prior to the procedure to augment some potential kidney toxicity however once this has occurred, there is not much that can be done other than the following: -Avoid potentially kidney toxic medications including over-the-counter medications such as ibuprofen or naproxen-Avoid changes in volume status such as with diuretics-Avoid overaggressive Chat Doctor.  If this is your situation then at this point he would have to wait and see where things stand about a month from now.  If contrast exposure included a catheter or guide wire, there is the added risk of atheroembolic renal insult (small debris from the wall of the blood vessel dislodged by the wire injuring the kidney).  Renal function recovery may or may not ensue. Again re-evaluation is required in about a months time Take care and be well </s>
