Sintesi
Vitamin C increases the amount of iron available for chelation by deferoxamine and can raise urinary iron excretion. In iron-overloaded patients, especially those with cardiac involvement, high-dose vitamin C has been linked to cardiac dysfunction, which can be serious.
Cosa significa questa interazione in parole semplici
Deferoxamine and Vitamin c can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Deferoxamine belongs to Miscellaneous; Vitamin c belongs to Gastrointestinal Tract.
Perché avviene
Ascorbic acid mobilizes tissue iron into a labile pool, which may increase iron-mediated myocardial toxicity while enhancing deferoxamine chelation.
Cosa fare
Avoid vitamin C in patients with cardiac dysfunction receiving deferoxamine. If it is used, start it only after a month of regular chelation, keep doses low, and monitor cardiac function.
Cosa chiedere al farmacista
