Micafungin 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.

Micafungin recalls
From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.
How long micafungin keeps
No micafungin label we read sets a separate limit for after opening, but they do specify how it must be stored — and the stability behind any date assumes those conditions.
Does micafungin expire? The in-use limits and storage rules from its labelsWhat people report to the FDA about micafungin
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,507 reports naming micafungin, and the FDA flagged 99% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- pyrexia197 reports
- febrile neutropenia169 reports
- pneumonia119 reports
- sepsis108 reports
- diarrhoea101 reports
- platelet count decreased88 reports
- white blood cell count decreased77 reports
- acute graft versus host disease in skin67 reports
Read these as a signal, not a rate. A report does not mean micafungin caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

What kind of drug is micafungin?
The FDA classifies micafungin as an echinocandin antifungal. If you are checking whether it is safe to combine with something else, the class is what matters — two drugs from the same class usually should not be stacked.
Can you take micafungin with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run micafungin against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
