Important Safety Information for Micafungin for Injection, 50mg and 100mg:
CONTRAINDICATIONS
Micafungin for injection is contraindicated in persons with known hypersensitivity to micafungin, any component of micafungin for injection, or other echinocandins.
WARNINGS & PRECAUTIONS
- Hypersensitivity 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.
- Hematological 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.
- Hepatic 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.
- 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 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.
- Infusion 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. 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.

There was no effect of single or multiple doses of micafungin for injection on cyclosporine, tacrolimus, prednisolone, voriconazole and fluconazole pharmacokinetics.
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.
USE IN SPECIFIC POPULATIONS
Pregnancy
Based on findings from animal studies, micafungin for injection may cause fetal harm when administered to a pregnant woman. 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. Advise pregnant women of the risk to the fetus.
Lactation
There are no data on the presence of micafungin in human milk, the effects on the breast-fed infant or the effects on milk production. Micafungin was present in the milk of lactating rats following intravenous administration. When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for micafungin for injection, and any potential adverse effects on the breast-fed child from micafungin for injection, or from the underlying maternal condition.
Pediatric Use
Pediatric Patients 4 Months of Age and Older
The safety and effectiveness of micafungin for injection for the treatment of esophageal candidiasis, candidemia, acute disseminated candidiasis, Candida peritonitis and abscesses, esophageal candidiasis, and for prophylaxis of Candida infections in patients undergoing HSCT have been established in pediatric patients 4 months of age and older.
Pediatric Patients Younger than 4 Months of Age
The safety and effectiveness of micafungin for injection have not been established for the treatment of candidemia with meningoencephalitis and/or ocular dissemination in pediatric patients younger than 4 months of age.
The safety and effectiveness of micafungin for injection in pediatric patients younger than 4 months of age have not been established for the:
- Treatment of esophageal candidiasis
- Prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation
Geriatric Use
A total of 418 subjects in clinical studies of micafungin for injection were 65 years of age and older, and 124 subjects were 75 years of age and older. No overall differences in safety and effectiveness were observed between these subjects and younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
The exposure and disposition of a 50 mg micafungin for injection dose administered as a single 1-hour infusion to 10 healthy subjects aged 66 to 78 years were not significantly different from those in 10 healthy subjects aged 20 to 24 years. No dose adjustment is necessary for the elderly.

Use in Patients with Hepatic Impairment
Dose adjustment of micafungin for injection is not required in patients with mild, moderate, or severe hepatic impairment.
Race and Gender
No dose adjustment of micafungin for injection is required based on gender or race. No notable differences among white, black, and Hispanic subjects were seen.
DOSAGE AND ADMINISTRATION
Dosage for Adults
The recommended dosage for adult patients based on indications are shown in Table 1 in the package insert.
Dosage for Pediatric Patients 4 Months and Older
The recommended dosage for pediatric patients 4 months of age and older based on indication and weight are shown in Table 2 in the package insert.
Directions for Reconstitution, Dilution, and Preparation
Do not mix or co-infuse micafungin for injection with other medications. 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:
- 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, 25°C (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 in the package insert] 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/mL for the 50 mg vial or 20 mg/mL for the 100 mg vial).
- 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/mL to 4 mg/ mL. To decrease the risk of infusion reactions, concentrations above 1.5 mg/mL should be administered via central catheter.
- Appropriately label the infusion bag or syringe. For concentrations above 1.5 mg/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, 25°C (77°F).
Micafungin for injection is preservative-free. Discard partially used vials.
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. 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/mL should be administered via central catheter.
DRUG ABUSE AND DEPENDENCE
There has been no evidence of either psychological or physical dependence or withdrawal or rebound effects with micafungin for injection.
OVERDOSAGE
