Pregnancy-Lactation
Pregnancy
There are no studies with use in pregnant women to inform drug-associated risks; administration of deferasirox to rats during pregnancy resulted in decreased offspring viability and an increase in renal anomalies in male offspring at doses that were about or less than recommended human dose on a mg/ m² basis; no fetal effects were noted in pregnant rabbits at doses equivalent to human recommended dose on a mg/ m² basis; drug should be used during pregnancy only if potential benefit justifies potential risk to fetus
Contraception
Counsel patients to use non-hormonal method(s) of contraception since drug can render hormonal contraceptives ineffective
Lactation
No data are available regarding presence of drug or its metabolites in human milk, effects on breastfed infant, or on milk production; drug and its metabolites is excreted in rat milk; because many drugs are excreted in human milk and because of potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue breastfeeding or to discontinue drug, taking into account importance of drug to mother
