Re: Interstitial Nephritis -- I began taking Prilosec in late 2011 for Acid Reflux. 5 months later I was in the hospital with kidney failure - my creatine was 2.98 at admission. I thought I just had some kind of virus, but I wasn't getting better that's when my PCP ordered blood tests and sent me to the emergency room. ER doc said my GFR was 16. Many tests and finally a biopsy confirmed interstitial nephritis. Kidney Doc said - no more Prilosec and I had a horrible withdrawal -- but my body finally adjusted. My kidney function is tested twice a year - Once thru my PCP and once thru the Kidney doc @ Vanderbilt. Creatine just tested again and it's now down to 1.04 - the lowest since 2011. A lot of other things go wrong when your kidney's fail. Vit D deficiency, Anemia - mine was fixed by iron infusions, Parathryoid counts too high requiring I take Calcitriol. Also no longer take any NSAIDS per doc instruction. Anemia was tough on me. Took several months to feel normal again after the iron infusions.
I now take Zantac for Acid Reflux and sometimes do not even need it. Sometimes I wonder about these OTC drugs... My husband and I both used to take a lot of Aleve, Advil. .. now we just take tylenol. We used to have all sorts of aches and pains, but no more. Strange..
