Triclabendazole, manufactured by Novartis pharmaceuticals, is an antihelminthic drug that was approved by the FDA in February 2019 for the treatment of fascioliasis in humans. Fascioliasis is a parasitic infection often caused by the helminth,Fasciola hepatica, which is also known as the common liver fluke or the sheep liver fluke or by Fasciola gigantica, another helminth. These parasites can infect humans following ingestion of larvae in contaminated water or food. Triclabendazole was previously used in the treatment of fascioliasis in livestock, but is now approved for human use. This drug is currently the only FDA-approved drug for individuals with fascioliasis, which affects 2.4 million people worldwide.
