Summary

Vitamin C may increase the pool of chelatable iron, and in iron overload it has been associated with greater iron toxicity, particularly cardiac effects, with deferoxamine. Data with deferasirox are limited, and modest vitamin C doses have not been associated with problems.

What this interaction means in plain words

Ascorbic acid and Deferasirox have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Evidence level: Low

Why it happens

Ascorbic acid may mobilize iron and increase redox-active iron, but the effect with deferasirox is not well established.

What to do

Avoid high-dose vitamin C supplementation in iron-overloaded patients. Keep doses modest and monitor ferritin and cardiac status in those with heart involvement.
