  • OTHER OPHTHALMOLOGICALS

What should I discuss with my healthcare provider before taking Sunkist Vitamin C (ascorbic acid)?

You should not use ascorbic acid if you have ever had an allergic reaction to a vitamin C supplement.

Ask a doctor or pharmacist about using ascorbic acid if you have:

  • kidney disease or a history of kidney stones;

  • hereditary iron overload disorder (hematochromatosis); or

  • if you smoke (smoking can make ascorbic acid less effective).

Your dose needs may be different during pregnancy or while you are breast-feeding a baby. Do not use ascorbic acid without your doctor's advice in either case.

How should I take Sunkist Vitamin C (ascorbic acid)?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

The recommended dietary allowance of vitamin C (ascorbic acid) increases with age. Follow your healthcare provider's instructions. You may also consult the Office of Dietary Supplements of the National Institutes of Health, or the U.S. Department of Agriculture (USDA) Nutrient Database (formerly "Recommended Daily Allowances") listings for more information.

Drink plenty of liquids while you are taking ascorbic acid.

The chewable tablet must be chewed before you swallow it.

Ascorbic acid gum may be chewed as long as desired and then thrown away.

Do not crush, chew, or break an extended-release tablet. Swallow it whole.

Measure liquid medicine with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Keep the orally disintegrating tablet in the package until you are ready to take it. Use dry hands to remove the tablet and place it in your mouth. Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. Swallow several times as the tablet dissolves.

Store ascorbic acid at room temperature away from moisture and heat.

Do not stop using ascorbic acid suddenly after long-term use at high doses, or you could have "conditional" vitamin C deficiency. Symptoms include bleeding gums, feeling very tired, and red or blue pinpoint spots around your hair follicles. Follow your doctor's instructions about tapering your dose. Conditional vitamin C deficiency can be difficult to correct without medical supervision.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

For Healthcare Professionals

Applies to ascorbic acid: compounding powder, injectable solution, oral capsule, oral gum, oral liquid, oral tablet, oral tablet chewable, oral tablet disintegrating, oral tablet extended release

Renal

Renal side effects have included oxalate and urate kidney stones.[Ref]

Hyperoxaluria appears to be dose-related.[Ref]

Nervous system

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]

Nervous system side effects have included dizziness, faintness, fatigue, and headache in less than 1% of patients. Migraine headache has also been reported.[Ref]

Other

Conditional scurvy is reported to occur following excessive doses of ascorbic acid (the active ingredient contained in Sunkist Vitamin C) 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]

Gastrointestinal

Gastrointestinal side effects have included nausea, diarrhea, abdominal cramps, and esophagitis.[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

The majority of hemolysis reports have been associated with patients who have concurrent glucose-6-phosphate dehydrogenase deficiency.[Ref]

Hematologic side effects have included hemolysis.[Ref]

Local

Local side effects have included transient mild soreness at the site of injection.[Ref]
