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 Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents, prepared by the U.S. Department of Health and Human Services (HHS) and the Centers for Disease Control and Prevention (CDC), 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.


What should I tell my health care provider before taking albendazole?


Before taking albendazole, tell your health care provider:

  • If you are allergic to albendazole or any other medicines.
  • About any medical conditions you have or have had, for example, diabetes or liver problems.
  • About anything that could affect your ability to take medicines, such as difficulty swallowing or remembering to take pills.
  • If you are pregnant or plan to become pregnant. Albendazole may cause harm to an unborn baby. Women should not begin treatment with albendazole until after a negative pregnancy test. Women should not become pregnant while on albendazole or within 1 month of completing treatment.
  • If you are breastfeeding or plan to breastfeed. Do not breastfeed if you are infected with HIV.
  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Ask your health care provider if there are interactions between albendazole and the other medicines you take.

Ask your health care provider about possible side effects from albendazole. Your health care provider will tell you what to do if you have side effects.
