• Ascorbic acid injection is indicated for the short term (up to 1 week) treatment of scurvy
• In pediatric patients age 5 months and older for whom oral administration is not possible, insufficient or contraindicated
• The safety profile of ascorbic acid
• In pediatric patients is similar to adults; however, pediatric patients less than 2 years of age may be at higher risk of oxalate nephropathy following ascorbic acid administration due to age-related decreased glomerular filtration [see Warnings and Precautions ]. …

Glomerular filtration rate is known to decrease with age and as such may increase risk for oxalate nephropathy following ascorbic acid administration in elderly population [see Warnings and Precautions (5.1) ] .

• Inform patients that treatment with ascorbic acid injection may increase their risk of oxalate nephropathy [see Warnings and Precautions ]. • Inform patients that treatment with ascorbic acid injection may impact laboratory results, including blood and urine glucose tests, up to 24 hours after infusion [see Warnings and Precautions ]. • Inform patients with glucose-6-phosphate dehydrogenase deficiency that treatment with ascorbic acid injection may increase their risk of hemolysis [see Warnings and Precautions ]

• Antibiotics: Ascorbic acid may decrease the activities of erythromycin, kanamycin, streptomycin, doxycycline, and lincomycin. Bleomycin is inactivated in vitro by ascorbic acid ( 7.1 ). • Amphetamine and Other Drugs Affected by Urine Acidification: Ascorbic acid may cause acidification of the urine and result in decreased amphetamine serum levels and affect excretion and plasma concentrations of other drugs sensitive to urine pH ( 7.2 ). • Warfarin: Continue standard monitoring ( 7.3 ). 7.1 Antibiotics Ascorbic acid may decrease activities of erythromycin, kanamycin, streptomycin, doxycycline, and lincomycin. Bleomycin is inactivated in vitro by ascorbic acid. …

• 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 ). …

The following adverse reactions are discussed in greater detail in other sections of the labeling: • Oxalate nephropathy and Nephrolithiasis [see Warnings and Precautions (5.1) ]. • Hemolysis in patients with glucose-6-phosphate dehydrogenase deficiency [see Warnings and Precautions (5.2) ]. The following adverse reactions associated with the use of ascorbic acid were identified in the literature. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure: Administration site reactions: pain and swelling. …
