Warnings and precautions
Hypersensitivity Reactions: Anaphylaxis and anaphylactoid reactions (including shock) have been observed. Discontinue micafungin for injection and administer appropriate treatment. (5.1) Hematological Effects: Isolated cases of acute intravascular hemolysis, hemolytic anemia and hemoglobinuria have been reported. Monitor rate of hemolysis. Discontinue if severe. (5.2) Hepatic Effects: Abnormalities in liver tests; isolated cases of hepatic impairment, hepatitis, and hepatic failure have been observed.
Monitor hepatic function. Discontinue if severe dysfunction occurs. (5.3) Renal Effects: Elevations in BUN and creatinine; isolated cases of renal impairment or acute renal failure have been reported. Monitor renal function. (5.4) Infusion and Injection Site Reactions can occur including rash, pruritus, facial swelling, and vasodilatation. Monitor infusion closely, slow infusion rate if necessary. (2.5, 5.5)
5.1Hypersensitivity Reactions
Isolated cases of serious hypersensitivity (anaphylaxis and anaphylactoid) reactions (including shock) have been reported in patients receiving micafungin for injection. If these reactions occur, micafungin for injection infusion should be discontinued and appropriate treatment administered.
5.2Hematological Effects
Acute intravascular hemolysis and hemoglobinuria was seen in a healthy volunteer during infusion of micafungin for injection (200 mg) and oral prednisolone (20 mg). Cases of significant hemolysis and hemolytic anemia have also been reported in patients treated with micafungin for injection. Patients who develop clinical or laboratory evidence of hemolysis or hemolytic anemia during micafungin for injection therapy should be monitored closely for evidence of worsening of these conditions and evaluated for the risk/benefit of continuing micafungin for injection therapy.
5.3Hepatic Effects
Laboratory abnormalities in liver function tests have been seen in healthy volunteers and patients treated with micafungin for injection. In some patients with serious underlying conditions who were receiving micafungin for injection along with multiple concomitant medications, clinical hepatic abnormalities have occurred, and isolated cases of significant hepatic impairment, hepatitis, and hepatic failure have been reported.
Patients who develop abnormal liver function tests during micafungin for injection therapy should be monitored for evidence of worsening hepatic function and evaluated for the risk/benefit of continuing micafungin for injection therapy.
5.4Renal Effects Elevations in BUN
and creatinine, and isolated cases of significant renal impairment or acute renal failure have been reported in patients who received micafungin for injection. In fluconazole-controlled trials, the incidence of drug-related renal adverse reactions was 0.4% for micafungin for injection-treated patients and 0.5% for fluconazole-treated patients. Patients who develop abnormal renal function tests during micafungin for injection therapy should be monitored for evidence of worsening renal function.
5.5Infusion and Injection Site Reactions
Possible histamine-mediated symptoms have been reported with micafungin for injection, including rash, pruritus, facial swelling, and vasodilatation. Slow the infusion rate if infusion reaction occurs [see Dosage and Administration (2.3)] . Injection site reactions, including phlebitis and thrombophlebitis have been reported, at micafungin for injection doses of 50 to 150 mg/day. These reactions tended to occur more often in patients receiving micafungin for injection via peripheral intravenous administration [see Dosage and Administration (2.3) and Adverse Reactions (6.1)] .
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 for Injection CYP3A4, CYP2C9 and CYP2C19 Inhibitors Co-administration of micafungin for injection with cyclosporine, itraconazole, voriconazole and fluconazole did not alter the pharmacokinetics of micafungin for injection. CYP2C19 and CYP3A4 Inducer Co-administration of micafungin for injection with rifampin and ritonavir did not alter the pharmacokinetics of micafungin for injection.
Co-administration of Micafungin for Injection with Other Drugs Co-administration of micafungin for injection with mycophenolate mofetil (MMF), amphotericin B, tacrolimus, prednisolone, sirolimus and nifedipine did not alter the pharmacokinetics of micafungin for injection.
7.2Effect of Micafungin for Injection on Other Drug 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.

6.1Clinical 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)] 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.

Prophylaxis of Candida Infections in Hematopoietic Stem Cell Transplant Recipients A double-blind trial was conducted in a total of 882 patients scheduled to undergo an autologous or allogeneic hematopoietic stem cell transplant. The median duration of treatment was 18 days (range 1 to 51 days) in both treatment arms. All adult patients who received micafungin for injection (382) or fluconazole (409) experienced at least one adverse reaction during the study.
Treatment-emergent adverse reactions resulting in micafungin for injection discontinuation were reported in 15 (4%) adult patients; while those resulting in fluconazole discontinuation were reported in 32 (8%).
