Hepatic impairment. Lactation. Monitoring Parameters Evaluate patients for manifestations of underlying cardiopulmonary disease prior to and during therapy. Measure full blood counts wkly for the 1st 2 mth and then mthly thereafter.
Lactation: not known if excreted in breast milk; do not nurse
Pregnancy-Lactation
Pregnancy
Based on limited human data, dasatinib can cause fetal harm when administered to a pregnant woman; adverse pharmacologic effects (eg, hydrops fetalis, fetal leukopenia, and fetal thrombocytopenia) have been reported with maternal exposure to dasatinib
Animal reproduction studies in rats have demonstrated extensive mortality during organogenesis, the fetal period, and in neonates; skeletal malformations were observed in a limited number of surviving rat and rabbit conceptuses; these findings occurred at dasatinib plasma concentrations below those in humans receiving therapeutic doses of dasatinib
Advise a pregnant woman of the potential risk to a fetus
Transplacental transfer of dasatinib has been reported
Advise females of reproductive potential to avoid pregnancy, which may include the use of effective contraceptive methods, during treatment with dasatinib and for 30 days after the final dose
Based on animal data, dasatinib may result in damage to female and male reproductive tissues
Lactation
No data are available regarding the presence of dasatinib in human milk, the effects of the drug on the breastfed child, or the effects of the drug on milk production
However, dasatinib is present in the milk of lactating rats
Interactions
Concomitant use w/ drugs that have narrow therapeutic index (e.g. alfentanil, cisapride, ciclosporin, fentanyl, pimozide, quinidine, simvastatin, sirolimus, tacrolimus, ergot alkaloids) as it may increase the serum levels of these drugs. Increased risk of bleeding and thrombocytopenia w/ antiplatelet drugs, anticoagulants, and NSAIDs.
Potentially Fatal: May reduce plasma levels w/ antacids, administer antacid 2 hr apart from the admin of dasatinib. May increase plasma levels w/ CYP3A4 inhibitors (e.g. atazanavir, clarithromycin, erythromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin or voriconazole). May reduce plasma levels w/ CYP3A4 inducers (e.g. carbamazepine, dexamethasone, phenytoin, phenobarbital or rifampicin).
