Clinical
Micafungin is used to treat certain fungal infections that have caused esophagitis ( infection of the throat), spread to the bloodstream, have caused abscesses (collection of pus in body tissue) or caused peritonitis (infection of the lining of the stomach) in adults and children. It is also used to prevent fungal infections in adults and children who have undergone a hematopoietic stem cell transplant (HSCT; procedure in which certain blood cells are removed from the body and then returned to the body). Micafungin is in a class of medications called echinocandins. It works by stopping the bui...

Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

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 , 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. Selected During IV Treatment + 3 days.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, Micafungin in Sodium Chloride Injection may cause fetal harm. Advise pregnant women of the risk to the fetus. ( 8.1 )
8.1Pregnancy 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.
8.2Lactation Risk Summary 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 in Sodium Chloride Injection, and any potential adverse effects on the breast-fed child from Micafungin in Sodium Chloride Injection, or from the underlying maternal condition.
8.4Pediatric Use Micafungin in Sodium Chloride Injection is indicated in pediatric patients for whom appropriate dosing with this formulation can be achieved. Because of the limitations of the available strengths and administration requirements (i.e., administration of fractional doses is not recommended) of Micafungin in Sodium Chloride Injection, and to avoid unintentional overdose, this product is not recommended for use if a dose of Micafungin in Sodium Chloride Injection that does not equal 50 mg, 100 mg, or 150 mg is required, and an alternative formulation of micafungin should be considered [ see Dosage and Administration (2.3 , 2.4 )].
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. Use of micafungin for these indications and in this age group is supported by evidence from adequate and well-controlled studies in adult and pediatric patients with additional pharmacokinetic and safety data in pediatric patients 4 months of age and older [ see Indications and Usage (1) , Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14) ] .

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.
🧒 Pediatric Use ▾
8.4Pediatric Use Micafungin in Sodium Chloride Injection is indicated in pediatric patients for whom appropriate dosing with this formulation can be achieved. Because of the limitations of the available strengths and administration requirements (i.e., administration of fractional doses is not recommended) of Micafungin in Sodium Chloride Injection, and to avoid unintentional overdose, this product is not recommended for use if a dose of Micafungin in Sodium Chloride Injection that does not equal 50 mg, 100 mg, or 150 mg is required, and an alternative formulation of micafungin should be considered [ see Dosage and Administration (2.3 , 2.4 )].
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. Use of micafungin for these indications and in this age group is supported by evidence from adequate and well-controlled studies in adult and pediatric patients with additional pharmacokinetic and safety data in pediatric patients 4 months of age and older [ see Indications and Usage (1) , Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14) ] .
Pediatric Patients Younger than 4 Months of Age Treatment of Candidemia, Acute Disseminated Candidiasis, Candida Peritonitis and Abscesses Without Meningoencephalitis and/or Ocular Dissemination in Pediatric Patients Younger Than 4 Months of Age The safety and effectiveness of micafungin for injection for the treatment of candidemia, acute disseminated candidiasis, Candida peritonitis and abscesses without meningoencephalitis and/or ocular dissemination at a dosage of 4 mg/kg once daily have been established in pediatric patients younger than 4 months of age.
This use and dosage of micafungin for injection are supported by evidence from adequate and well-controlled studies in adult and pediatric patients 4 months of age and older with additional pharmacokinetic and safety data in pediatric patients younger than 4 months of age [ see Adverse Reactions (6.1) and Clinical Pharmacology (12.3) ] . Treatment of Candidemia, Acute Disseminated Candidiasis, Candida Peritonitis and Abscesses With Meningoencephalitis and/or Ocular Dissemination in 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.
In a rabbit model of hematogenous Candida meningoencephalitis (HCME) with Candida albicans (minimum inhibitory concentration of 0.125 mcg/mL), a decrease in mean fungal burden in central nervous system (CNS) compartments assessed as the average of combined fungal burden in the cerebrum, cerebellum, and spinal cord relative to untreated controls, was observed with increasing micafungin dosages administered once daily for 7 days. Data from the rabbit model suggest that a micafungin dose regimen of 4 mg/kg once daily is inadequate to treat meningoencephalitis and that a dose regimen of approximately 10 to 25 mg/kg once daily may be necessary to lower fungal burden in the CNS in pediatric patients younger than 4 months of age [ see Microbiology (12.4) ] .
In this rabbit model, micafungin concentrations could not be reliably detected in cerebrospinal fluid (CSF). Due to limitations of the study design, the clinical significance of a decreased CNS fungal burden in the rabbit HCME model is uncertain. A randomized controlled trial evaluated a micafungin for injection dose regimen of 10 mg/kg once daily in pediatric patients younger than 4 months of age with suspected or proven Candida meningoencephalitis.

🧓 Geriatric Use ▾
8.5Geriatric 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. Each 50 mg/50 mL Galaxy container of Micafungin in Sodium Chloride Injection contains 200 mg of sodium, each 100 mg/100 mL Galaxy container of Micafungin in Sodium Chloride Injection contains 400 mg of sodium, and each 150 mg/150 mL Galaxy container of Micafungin in Sodium Chloride Injection contains 600 mg of sodium.
The geriatric population may respond with a blunted natriuresis to salt loading. This may be clinically important with regard to such diseases as congestive heart failure and other conditions requiring restricted sodium intake [ see Warnings and Precautions (5.6 )] .
🆘 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) ].

14 CLINICAL STUDIES
14.1Treatment of Candidemia and Other Candida Infections in Adult and Pediatric Patients 4 Months of Age and Older Two dose levels of micafungin for injection were evaluated in a randomized, double-blind study to determine the efficacy and safety versus caspofungin in patients with invasive candidiasis and candidemia. Patients were randomized to receive once daily intravenous infusions (IV) of micafungin for injection, either 100 mg/day or 150 mg/day or caspofungin (70 mg loading dose followed by 50 mg maintenance dose).
Patients in both study arms were permitted to switch to oral fluconazole after at least 10 days of intravenous therapy, provided they were non-neutropenic, had improvement or resolution of clinical signs and symptoms, had a Candida isolate which was susceptible to fluconazole, and had documentation of 2 negative cultures drawn at least 24 hours apart. Patients were stratified by APACHE II score (20 or less or greater than 20) and by geographic region. Patients with Candida endocarditis were excluded from this analysis.
Outcome was assessed by overall treatment success based on clinical (complete resolution or improvement in attributable signs and symptoms and radiographic abnormalities of the Candida infection and no additional antifungal therapy) and mycological (eradication or presumed eradication) response at the end of IV therapy. Deaths that occurred during IV study drug therapy were treated as failures. In this study, 111/578 (19.2%) of the patients had baseline APACHE II scores of greater than 20, and 50/578 (8.7%) were neutropenic at baseline (absolute neutrophil count less than 500 cells/mm 3 ).

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Hepatic carcinomas and adenomas were observed in a 6-month intravenous toxicology study with an 18-month recovery period of micafungin sodium in rats designed to assess the reversibility of hepatocellular lesions. Rats administered micafungin sodium for 3 months at 32 mg/kg/day (corresponding to 8 times the highest recommended human dose [150 mg/day], based on AUC comparisons), exhibited colored patches/zones, multinucleated hepatocytes and altered hepatocellular foci after 1 or 3-month recovery periods, and adenomas were observed after a 21-month recovery period.
Rats administered micafungin sodium at the same dose for 6 months exhibited adenomas after a 12-month recovery period; after an 18-month recovery period, an increased incidence of adenomas was observed and, additionally, carcinomas were detected. A lower dose of micafungin sodium (equivalent to 5 times the human AUC) in the 6-month rat study resulted in a lower incidence of adenomas and carcinomas following 18 months recovery. The duration of micafungin dosing in these rat studies (3 or 6 months) exceeds the usual duration of Micafungin in Sodium Chloride Injection dosing in patients, which is typically less than 1 month for treatment of esophageal candidiasis, but dosing may exceed 1 month for Candida prophylaxis.
Although the increase in carcinomas in the 6-month rat study did not reach statistical significance, the persistence of altered hepatocellular foci subsequent to micafungin for injection dosing, and the presence of adenomas and carcinomas in the recovery periods suggest a causal relationship between micafungin sodium, altered hepatocellular foci, and hepatic neoplasms. Whole-life carcinogenicity studies of micafungin for injection in animals have not been conducted, and it is not known whether the hepatic neoplasms observed in treated rats also occur in other species, or if there is a dose threshold for this effect.
Micafungin sodium was not mutagenic or clastogenic when evaluated in a standard battery of in vitro and in vivo tests (i.e., bacterial reversion - S. typhimurium, E. coli ; chromosomal aberration; intravenous mouse micronucleus). Male rats treated intravenously with micafungin sodium for 9 weeks showed vacuolation of the epididymal ductal epithelial cells at or above 10 mg/kg (about 0.6 times the recommended clinical dose for esophageal candidiasis, based on body surface area comparisons). Higher doses (about twice the recommended clinical dose, based on body surface area comparisons) resulted in higher epididymis weights and reduced numbers of sperm cells.
In a 39-week intravenous study in dogs, seminiferous tubular atrophy and decreased sperm in the epididymis were observed at 10 and 32 mg/kg, doses equal to about 2 and 7 times the recommended clinical dose, based on body surface area comparisons. There was no impairment of fertility in animal studies with micafungin sodium.
13.2Animal Toxicology and/or Pharmacology High doses of micafungin sodium (5 to 8 times the highest recommended human dose, based on AUC comparisons) have been associated with irreversible changes to the liver when administered for 3 or 6 months, and these changes may be indicative of pre-malignant processes [ see Nonclinical Toxicology (13.1 )].
📄 Carcinogenesis, Mutagenesis, Impairment of Fertility ▾
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Hepatic carcinomas and adenomas were observed in a 6-month intravenous toxicology study with an 18-month recovery period of micafungin sodium in rats designed to assess the reversibility of hepatocellular lesions. Rats administered micafungin sodium for 3 months at 32 mg/kg/day (corresponding to 8 times the highest recommended human dose [150 mg/day], based on AUC comparisons), exhibited colored patches/zones, multinucleated hepatocytes and altered hepatocellular foci after 1 or 3-month recovery periods, and adenomas were observed after a 21-month recovery period.
Rats administered micafungin sodium at the same dose for 6 months exhibited adenomas after a 12-month recovery period; after an 18-month recovery period, an increased incidence of adenomas was observed and, additionally, carcinomas were detected. A lower dose of micafungin sodium (equivalent to 5 times the human AUC) in the 6-month rat study resulted in a lower incidence of adenomas and carcinomas following 18 months recovery. The duration of micafungin dosing in these rat studies (3 or 6 months) exceeds the usual duration of Micafungin in Sodium Chloride Injection dosing in patients, which is typically less than 1 month for treatment of esophageal candidiasis, but dosing may exceed 1 month for Candida prophylaxis.
Although the increase in carcinomas in the 6-month rat study did not reach statistical significance, the persistence of altered hepatocellular foci subsequent to micafungin for injection dosing, and the presence of adenomas and carcinomas in the recovery periods suggest a causal relationship between micafungin sodium, altered hepatocellular foci, and hepatic neoplasms. Whole-life carcinogenicity studies of micafungin for injection in animals have not been conducted, and it is not known whether the hepatic neoplasms observed in treated rats also occur in other species, or if there is a dose threshold for this effect.
Micafungin sodium was not mutagenic or clastogenic when evaluated in a standard battery of in vitro and in vivo tests (i.e., bacterial reversion - S. typhimurium, E. coli ; chromosomal aberration; intravenous mouse micronucleus). Male rats treated intravenously with micafungin sodium for 9 weeks showed vacuolation of the epididymal ductal epithelial cells at or above 10 mg/kg (about 0.6 times the recommended clinical dose for esophageal candidiasis, based on body surface area comparisons). Higher doses (about twice the recommended clinical dose, based on body surface area comparisons) resulted in higher epididymis weights and reduced numbers of sperm cells.
In a 39-week intravenous study in dogs, seminiferous tubular atrophy and decreased sperm in the epididymis were observed at 10 and 32 mg/kg, doses equal to about 2 and 7 times the recommended clinical dose, based on body surface area comparisons. There was no impairment of fertility in animal studies with micafungin sodium.
