En senere undersøgelse sammenlignede en behandling, der vekslede mellem Ferriprox og deferoxamin (fem dages Ferriprox plus to dages deferoxamin hver uge) med en kontinuerlig behandling med deferoxamin alene hos 60 patienter over en periode på 12 måneder.
A later study compared treatment alternating Ferriprox and deferoxamine (five days ’ Ferriprox plus two days ’ deferoxamine each week) with continuous treatment with deferoxamine on its own, in 60 patients over 12 months.
