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 is also used to treat certain types of Microsporidiosis. Microsporidiosis is an opportunistic infection (OI) of HIV. An OI is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as people with HIV—than in people with healthy immune systems. To learn more about OIs, read the Clinical Info What is an Opportunistic Infection? fact sheet.

The Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents include recommendations on the HIV-related uses of albendazole.

Using a medicine as indicated on the medicine label is called on-label use; using the medicine in a different way is called off-label use. Off-label use, for example, can include using a drug for a different disease or medical condition. Good medical practice and the best interests of a patient sometimes require that a medicine be used off-label.

The guidelines include recommendations on the off-label uses of albendazole to treat the following types of Microsporidiosis:

  • Intestinal and disseminated infection caused by certain types of microsporidia
  • Ocular infection

The above list may not include all of the HIV-related uses of albendazole recommended in the guidelines. Some recommended uses, such as uses in certain rare circumstances, may have been omitted.
