Nephrotoxicity, nausea and vomiting (30-100%), myelosuppression, electrolyte anomalies, peripheral neuropathy, ototoxicity and anaphylaxis, haemolytic anaemia (rare), optic neuritis (rare), reversible posterior leucoencephalopathy syndrome (rare), seizures (rare), ECG changes (rare) and heart failure (rare).
The scarring of the small blood vessels, called capillary sclerosis, is the initial lesion of analgesic nephropathy. [7] Found in the renal pelvis, ureter, and capillaries supplying the nephrons, capillary sclerosis is thought to lead to renal papillary necrosis and, in turn, chronic interstitial nephritis.
Allopurinol is used to reduce urate formation in conditions where urate deposition has already occurred or is predictable. The specific diseases and conditions where it is used include gouty arthritis, skin tophi, kidney stones, idiopathic gout; uric acid lithiasis; acute uric acid nephropathy; neoplastic disease and myeloproliferative disease with high cell turnover rates, in which high urate ...

[10] It was approved for medical use in the United States and in the European Union in 2015, [11] [12] [13] [7] and in Australia in 2016.
