( 6.1 ) In pediatric patients younger than 4 months of age, the following additional common adverse reactions were reported at an incidence rate of ≥15%: hypokalemia, acidosis, sepsis, anemia, and oxygen saturation decreased. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Baxter Healthcare Corporation at 1-866-888-2472 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of micafungin for injection cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. The overall safety of micafungin for injection was assessed in 520 healthy volunteers and 3417 adult and pediatric patients who received single or multiple doses of micafungin for injection across 50 clinical trials, including the invasive candidiasis, esophageal candidiasis and prophylaxis trials. The doses of micafungin for injection administered included doses above and below the recommended doses [ see Dosage and Administration (2.1 , 2.2 , 2.3 )] and ranged from 0.75 mg/kg to 15 mg/kg in pediatric patients and 12.5 mg to 150 mg/day or greater in adults. Clinical Trials Experience in Adults In clinical trials with micafungin for injection, 2497/2748 (91%) adult patients experienced at least one adverse reaction. Candidemia and Other Candida Infections In a randomized, double-blind trial for the treatment of candidemia and other Candida infections, adverse reactions occurred in 183/200 (92%) and 171/193 (89%) patients in the micafungin for injection 100 mg/day, and caspofungin (70 mg loading dose followed by 50 mg/day dose) treatment groups, respectively. Selected adverse reactions occurring in 5% or more of the patients and more frequently in the micafungin for injection treatment group, are shown in Table 3 . Table 3.

7 DRUG INTERACTIONS Monitor for sirolimus, itraconazole or nifedipine toxicity, and dosage of sirolimus, itraconazole or nifedipine should be reduced, if necessary. ( 7 ) 7.1 Effect of Other Drugs on Micafungin in Sodium Chloride Injection CYP3A4, CYP2C9 and CYP2C19 Inhibitors Co-administration of Micafungin in Sodium Chloride Injection with cyclosporine, itraconazole, voriconazole and fluconazole did not alter the pharmacokinetics of micafungin. CYP2C19 and CYP3A4 Inducer Co-administration of Micafungin in Sodium Chloride Injection with rifampin and ritonavir did not alter the pharmacokinetics of micafungin. Co-administration of Micafungin in Sodium Chloride Injection with Other Drugs Co-administration of Micafungin in Sodium Chloride Injection with mycophenolate mofetil (MMF), amphotericin B, tacrolimus, prednisolone, sirolimus and nifedipine did not alter the pharmacokinetics of micafungin. 7.2 Effect of Micafungin in Sodium Chloride Injection on Other Drugs CYP3A4 Substrates There was no effect of single or multiple doses of micafungin for injection on cyclosporine, tacrolimus, prednisolone, voriconazole and fluconazole pharmacokinetics. Sirolimus AUC was increased by 21% with no effect on C max in the presence of steady-state micafungin for injection compared with sirolimus alone. Nifedipine AUC and C max were increased by 18% and 42%, respectively, in the presence of steady-state micafungin for injection compared with nifedipine alone. Itraconazole AUC and C max were increased by 22% and 11%, respectively. Patients receiving sirolimus, nifedipine, and itraconazole in combination with micafungin for injection should be monitored for sirolimus, nifedipine, and itraconazole toxicity and the sirolimus, nifedipine, and itraconazole dosage should be reduced if necessary. UDP-Glycosyltransferase Substrate Co-administration of mycophenolate mofetil (MMF) with micafungin for injection did not alter the pharmacokinetics of MMF.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on findings from animal studies, Micafungin for Injection may cause fetal harm when administered to a pregnant woman (see Data) . There is insufficient human data on the use of micafungin for injection in pregnant women to inform a drug-associated risk of adverse developmental outcomes. In animal reproduction studies, intravenous administration of micafungin sodium to pregnant rabbits during organogenesis at doses four times the maximum recommended human dose resulted in visceral abnormalities and increased abortion (see Data) . Advise pregnant women of the risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data In an embryo-fetal toxicity study in pregnant rabbits, intravenous administration of micafungin sodium during organogenesis (days 6 to 18 of gestation) resulted in fetal visceral abnormalities and abortion at 32 mg/kg, a dose equivalent to four times the recommended human dose based on body surface area comparisons. Visceral abnormalities included abnormal lobation of the lung, levocardia, retrocaval ureter, anomalous right subclavian artery, and dilatation of the ureter.
Overdosage
10 OVERDOSAGE Micafungin is highly protein bound and, therefore, is not dialyzable. No cases of micafungin for injection overdosage have been reported. Repeated daily doses up to 8 mg/kg (maximum total dose of 896 mg) in adult patients, up to 6 mg/kg in pediatric patients 4 months of age and older, and up to 15 mg/kg in pediatric patients younger than 4 months of age have been administered in clinical trials with no reported dose-limiting toxicity [ see Adverse Reactions (6.1) and Use in Specific Populations (8.4) ].
