Amphotericin B Injection Shortage

Last Updated: May 28, 2019
Status: Resolved

Reason for the Shortage
    • X-Gen had amphotericin B on shortage due to manufacturing delays. They are the sole suppliers of amphotericin B lyophilized powder for injection.[1]
    • Lipid-based amphotericin is not affected by this shortage.
Available Products
    • Amphotericin B lyophilized powder for injection, X-Gen, 50 mg, vial, 1 count, NDC 39822-1055-05

Estimated Resupply Dates

    • X-Gen has amphotericin B 50 mg vials available.[1]

Alternative Agents & Management

    • Hospitals should consider reserving supply of conventional amphotericin B for patients who require intrathecal or ophthalmic treatment due to the small amount of data available with liposomal amphotericin B.
    • Intrathecal liposomal amphotericin B has been used to treat cryptococcal central nervous system infections. One study used AmBisome 5 mg/mL 2 mL mixed with 3 mL of 5% dextrose for treatment of cryptococcal meningitis in HIV-infected patients.[2]
