• Oxalate nephropathy and Nephrolithiasis : Ascorbic acid has been associated with development of acute or chronic oxalate nephropathy following prolonged use of high doses of ascorbic acid infusion. Patients with renal disease including renal impairment, history of oxalate kidney stones, geriatric patients, and pediatric patients less than 2 years old may be at increased risk ( 5.1 ). • Hemolysis : Patients with glucose-6-phosphate dehydrogenase deficiency are at risk of severe hemolysis; a reduced dose is recommended ( 5.2 ). • Laboratory Test Interference: Ascorbic acid may interfere with laboratory tests based on oxidation-reduction reactions, including blood and urine glucose testing ( 5.3 ). 5.1 Oxalate Nephropathy and Nephrolithiasis Acute and chronic oxalate nephropathy have been reported with prolonged administration of high doses of ascorbic acid. Acidification of the urine by ascorbic acid may cause precipitation of cysteine, urate or oxalate stones. Patients with renal disease including renal impairment, history of oxalate kidney stones, and geriatric patients may be at increased risk for oxalate nephropathy while receiving treatment with ascorbic acid. Pediatric patients less than 2 years of age may be at increased risk for oxalate nephropathy during treatment with ascorbic acid because their kidneys are immature [see Use in Specific Populations (8.4, 8.5, 8.6) ] . Monitor renal function in patients at increased risk receiving ascorbic Acid Injection. …

8.1 Pregnancy Risk Summary There are no available data on use of ascorbic acid injection in pregnant women to inform a drug-associated risk of adverse developmental outcomes; however, use of ascorbic acid (vitamin C) has been used during pregnancy for several decades and no adverse developmental outcomes are reported in the published literature [see Data]. There are dose adjustments for ascorbic acid (vitamin C) use during pregnancy [see Clinical Considerations]. Animal reproduction studies have not been conducted with ascorbic acid injection. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk …
