Documented Uses

• Veterinary Drug -> ANTHELMINTHIC_AGENT -> JECFA Functional Classes
• This drug is indicated for the treatment of fascioliasis in patients aged 6 years old and above.
• Triclabendazole is an oral anthelmintic used in the treatment of chronic fascioliasis also known as liver flukes. Triclabendazole therapy is generally well tolerated but can be accompanied by abdominal pain, nausea and mild liver test abnormalities, which are probably due to the expulsion of dead or dying flukes rather than hepatic injury due to the therapy.
