Micafungin for injection has been shown to precipitate when mixed directly with a number of other commonly used medications. Please read this entire section carefully before beginning reconstitution. Reconstitution Reconstitute micafungin for injection vials by aseptically adding 5 mL of one of the following compatible solutions: 0.9% Sodium Chloride Injection, USP (without a bacteriostatic agent) 5% Dextrose Injection, USP To minimize excessive foaming, gently dissolve the micafungin for injection powder by swirling the vial. Do not vigorously shake the vial . Visually inspect the vial for particulate matter. Micafungin for injection 50 mg vial : after reconstitution each mL contains 10 mg of micafungin. Micafungin for injection 100 mg vial : after reconstitution each mL contains 20 mg of micafungin. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if there is any evidence of precipitation or foreign matter. Aseptic technique must be strictly observed in all handling since no preservative or bacteriostatic agent is present in micafungin for injection or in the materials specified for reconstitution and dilution. The reconstituted product should be protected from light and may be stored in the original vial for up to 24 hours at room temperature, 20° to 25°C (68° to 77°F). Dilution and Preparation The diluted solution should be protected from light. It is not necessary to cover the infusion drip chamber or the tubing. Adult Patients Add the appropriate volume of reconstituted micafungin for injection into 100 mL of 0.9% Sodium Chloride Injection, USP or 100 mL of 5% Dextrose Injection, USP. Appropriately label the bag. Pediatric Patients Calculate the total micafungin for injection dose in milligrams (mg) by multiplying the recommended pediatric dose (mg/kg) for a given indication [see Table 2 ] and the weight of the patient in kilograms (kg). To calculate the volume (mL) of drug needed, divide the calculated dose (mg) from step 1 by the final concentration of the selected reconstituted vial(s) (either 10 mg per mL for the 50 mg vial or 20 mg per mL for the 100 mg vial), see example below: Using 50 mg vials Divide the calculated mg dose (from step 1) by 10 mg per mL to determine the volume (mL) needed. OR Using 100 mg vials Divide the calculated mg dose (from step 1) by 20 mg per mL to determine the volume (mL) needed. Withdraw the calculated volume (mL) of drug needed from the selected concentration and size of reconstituted micafungin for injection vial(s) used in Step 2 (ensure the selected concentration and vial size used to calculate the dose is also used to prepare the infusion). Add the withdrawn volume of drug (step 3) to a 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP intravenous infusion bag or syringe. Ensure that the final concentration of the solution is between 0.5 mg per mL to 4 mg per mL. To decrease the risk of infusion reactions, concentrations above 1.5 mg per mL should be administered via central catheter [see Warnings and Precautions ( 5.5 )] . Appropriately label the infusion bag or syringe. For concentrations above 1.5 mg per mL, if required, label to specifically warn to administer the solution via central catheter. The diluted infusion bag should be protected from light and may be stored for up to 24 hours at room temperature, 20° to 25°C (68° to 77°F). Micafungin for injection is preservative-free. Discard partially used vials. 2.5 Infusion Volume and Duration Administer micafungin for injection by intravenous infusion only. Infuse over one hour. More rapid infusions may result in more frequent histamine-mediated reactions [see Warnings and Precautions ( 5.5 )] . Flush an existing intravenous line with 0.9% Sodium Chloride Injection, USP, prior to infusion of micafungin for injection. Pediatric Patients Micafungin for injection should be infused over one hour. To decrease the risk of infusion reactions, concentrations above 1.5 mg per mL should be administered via central catheter [see Warnings and Precautions ( 5.5 )] .

4 CONTRAINDICATIONS Micafungin is contraindicated in persons with known hypersensitivity to micafungin, any component of micafungin, or other echinocandins. Micafungin is contraindicated in persons with known hypersensitivity to micafungin sodium, any component of micafungin, or other echinocandins. ( 4 )

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Anaphylaxis and anaphylactoid reactions (including shock) have been observed. Discontinue micafungin 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 ) 5.1 Hypersensitivity Reactions Isolated cases of serious hypersensitivity (anaphylaxis and anaphylactoid) reactions (including shock) have been reported in patients receiving micafungin. If these reactions occur, micafungin infusion should be discontinued and appropriate treatment administered. 5.2 Hematological Effects Acute intravascular hemolysis and hemoglobinuria was seen in a healthy volunteer during infusion of micafungin (200 mg) and oral prednisolone (20 mg). Cases of significant hemolysis and hemolytic anemia have also been reported in patients treated with micafungin. Patients who develop clinical or laboratory evidence of hemolysis or hemolytic anemia during micafungin therapy should be monitored closely for evidence of worsening of these conditions and evaluated for the risk/benefit of continuing micafungin therapy. 5.3 Hepatic Effects Laboratory abnormalities in liver function tests have been seen in healthy volunteers and patients treated with micafungin. In some patients with serious underlying conditions who were receiving micafungin 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 therapy should be monitored for evidence of worsening hepatic function and evaluated for the risk/benefit of continuing micafungin therapy. 5.4 Renal 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. In fluconazole-controlled trials, the incidence of drug-related renal adverse reactions was 0.4% for micafungin-treated patients and 0.5% for fluconazole-treated patients. Patients who develop abnormal renal function tests during micafungin therapy should be monitored for evidence of worsening renal function. 5.5 Infusion and Injection Site Reactions Possible histamine-mediated symptoms have been reported with micafungin, including rash, pruritus, facial swelling, and vasodilatation. Slow the infusion rate if infusion reaction occurs [see Dosage and Administration ( 2.5 )]. Injection site reactions, including phlebitis and thrombophlebitis have been reported, at micafungin doses of 50 to 150 mg/day. These reactions tended to occur more often in patients receiving micafungin via peripheral intravenous administration [see Dosage and Administration ( 2.5 ) and Adverse Reactions ( 6.1 )].

7 DRUG INTERACTIONS Monitor for sirolimus, itraconazole or nifedipine toxicity, and dosage of sirolimus, itraconazole or nifedipine should be reduced, if necessary.

Of the 479 pediatric patients, 264 (55%) were male, 319 (67%) were white, with the following age distribution: 116 (24%) to <2 years, 108 (23%) 2 to 5 years, 140 (29%) 6 to 11 years, and 115 (24%) 12 to 16 years of age. The mean treatment duration was 24.8 days. A total of 246 patients received at least one dose of micafungin ranging from 2 to 10 mg/kg. Overall, 439/479 (92%) patients experienced at least one adverse reaction. Adverse reactions occurring in ≥15% or more of micafungin-treated pediatric patients are: vomiting (31%), diarrhea (22%), pyrexia (22%), nausea (19%), abdominal pain (16%), and thrombocytopenia (15%). Two randomized, double-blind active-controlled trials included pediatric patients. In the invasive candidiasis/candidemia trial, the efficacy and safety of micafungin (2 mg/kg/day for patients weighing 40 kg or less and 100 mg/day for patients weighing greater than 40 kg) was compared to amphotericin B liposome (3 mg/kg/day) in 112 pediatric patients. Treatment-emergent adverse reactions occurred in 51/56 (91%) of patients in the micafungin group and 52/56 (93%) of patients in the amphotericin B liposome group. Treatment-emergent adverse reactions resulting in drug discontinuation were reported in 2 (4%) micafungin-treated pediatric patients and in 9 (16%) amphotericin B liposome-treated pediatric patients. The prophylaxis study in patients undergoing HSCT investigated the efficacy of micafungin (1 mg/kg/day for patients weighing 50 kg or less and 50 mg/day for patients weighing greater than 50 kg) as compared to fluconazole (8 mg/kg/day for patients weighing 50 kg or less and 400 mg/day for patients weighing greater than 50 kg). All 91 pediatric patients experienced at least one treatment-emergent adverse reaction. Three (7%) pediatric patients discontinued micafungin due to adverse reaction, while one (2%) patient discontinued fluconazole. Selected adverse reactions, occurring in 15% or more of the patients and more frequently in a micafungin group, for the two comparative trials are shown in Table 6 . Table 6.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and lymphatic system disorders: disseminated intravascular coagulation Hepatobiliary disorders: hepatic disorder Renal and urinary disorders: renal impairment Skin and subcutaneous tissue disorders: Stevens-Johnson syndrome, toxic epidermal necrolysis Vascular disorders: shock

8.1 Pregnancy Risk Summary Based on findings from animal studies, micafungin may cause fetal harm when administered to a pregnant woman (see Data ) . There is insufficient human data on the use of micafungin 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.
