From the Guidelines

No, fenbendazole and ivermectin are not recommended for treating Candida infections. These medications are antiparasitic drugs primarily used to treat worm infestations and certain parasitic conditions, not fungal infections like candidiasis. For Candida infections, antifungal medications such as fluconazole (typically 150-200mg daily for 7-14 days for uncomplicated infections), nystatin (oral suspension or topical forms), or clotrimazole (topical application) are the appropriate treatments, as recommended by the Infectious Diseases Society of America 1. The reason these antiparasitics don't work against Candida is that they target specific biological pathways in parasites that don't exist in fungi. Candida, being a fungal organism, has a different cell structure and metabolic processes than parasites. Using inappropriate medications like fenbendazole or ivermectin for fungal infections would be ineffective and potentially delay proper treatment, allowing the infection to worsen. If you suspect a Candida infection, consult a healthcare provider for proper diagnosis and treatment with appropriate antifungal medications.

Some key points to consider:

  • The treatment of Candida infections depends on the severity and location of the infection, as well as the patient's overall health status 1.
  • Fluconazole is a commonly used antifungal medication for treating Candida infections, particularly for uncomplicated cases 1.
  • Other antifungal medications, such as echinocandins and amphotericin B, may be used for more severe or complicated cases 1.
  • It's essential to consult a healthcare provider for proper diagnosis and treatment of Candida infections, as inappropriate treatment can lead to delayed recovery or worsening of the infection 1.

In summary, fenbendazole and ivermectin are not suitable treatments for Candida infections, and antifungal medications like fluconazole, nystatin, or clotrimazole should be used instead, under the guidance of a healthcare provider 1.

From the Research

Treatment of Candida Infections

  • There is no direct evidence to suggest that fenbendazole or ivermectin can be used to treat candida infections 2.
  • The provided studies focus on the efficacy of fenbendazole and ivermectin against various parasites, such as Trichuris spp. 3, helminths in horses 4, Capillaria plica 5, and Nematodirus battus infections in lambs 6.
  • None of the studies mention the treatment of candida infections using fenbendazole or ivermectin.
  • Itraconazole, on the other hand, has been shown to be effective against Candida species, including non-albicans Candida 2.

Efficacy of Fenbendazole and Ivermectin

  • Fenbendazole and ivermectin have been shown to be effective against certain parasites, such as Trichuris spp. 3 and helminths in horses 4.
  • However, their efficacy against candida infections is unknown based on the provided studies.
  • Further research would be needed to determine the potential effectiveness of fenbendazole and ivermectin against candida infections 3, 4, 5, 6.
