Renal Dose

CrCl 40-60 mL/min: Reduce starting dose by 50%
Serum Cr >2 xULN or CrCl <40 mL/min: Do not use
Contraindication
Hypersensitivity.
Mode of Action
Deferasirox is an orally active chelator that is selective for iron (as Fe3+ ion). It is a tridentate ligand that binds iron with high affinity in a 2:1 ratio. It is used in the management of chronic iron overload.
Precaution
Monitor renal function and CBC before starting treatment and regularly during treatment; may need to reduce dose or stop treatment if serum creatinine levels are persistently elevated. May increase LFTs. Perform audiological and ophthamological tests before starting treatment and yrly thereafter. Pregnancy.
