Hyperoxaluria appears to be dose-related.[Ref]
Migraine headache has been reported with a daily dose of 6 grams.
The manufacturer reports temporary dizziness and faintness may be associated with too rapid of a rate during intravenous administration.[Ref]
Conditional scurvy is reported to occur following excessive doses of ascorbic acid (the active ingredient contained in Cemill 500) over a prolonged period of time. The mechanism of action for this condition is thought to be that large doses of ascorbic acid condition the patient over time for rapid clearance of ascorbic acid resulting in scurvy. The plasma levels of ascorbic acid appear to remain within normal limits. The actual existence of conditional scurvy remains controversial.[Ref]
Other side effects have included flank pain in less than 1% of patients. Conditional scurvy has also been reported.[Ref]
Nausea, diarrhea, and abdominal cramps appears to be associated with doses exceeding 2 g per day, although there have been some reports with as little as 1 g per day.
Esophagitis appears to be associated with prolonged or increased contact of ascorbic acid tablets with the esophageal mucosa.[Ref]
Hematologic side effects have included hemolysis.[Ref]
The majority of hemolysis reports have been associated with patients who have concurrent glucose-6-phosphate dehydrogenase deficiency.[Ref]
Local side effects have included transient mild soreness at the site of injection.[Ref]
