What is albendazole?
Albendazole is an anti-parasitic prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of two parasitic infections: neurocysticercosis and hydatid disease.
Albendazole can also be used “off-label” to treat opportunistic infections of HIV infection.
- “Off-label” use refers to use of an FDA-approved medicine in a manner different from that described on the medicine label. Good medical practice and the best interests of a patient sometimes require that a medicine be used “off-label.”
- An opportunistic infection is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as those infected with HIV—than in people with healthy immune systems.
What HIV-related opportunistic infections is albendazole used for?
The Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents, prepared by the Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH), and the HIV Medicine Association of the Infectious Diseases Society of America (IDSA-HIVMA), includes recommendations on the “off-label” HIV-related use of albendazole to treat microsporidiosis, an infection caused by any one of many parasites belonging to the group called microsporidia.
