Product description :
Levamisole (marketed as the hydrochloride salt under the trade name Ergamisol) is an anthelminthic and immunomodulator belonging to a class of synthetic imidazothiazole derivatives. It was discovered at Janssen Pharmaceutica in 1966. Levamisole has been used in humans to treat parasitic worm infections, and has been studied in combination with other forms of chemotherapy for colon cancer, melanoma, and head and neck cancer. The drug was withdrawn from the U.S. and Canadian markets in 2000 and 2003 respectively, due to the risk of serious side effects and the availability of more effective replacement medications.

Currently, levamisole remains in veterinary use as a dewormer for livestock. The medication has also been increasingly used as an adulterant in cocaine sold in the U.S. and Canada, resulting in serious side effects.
