Praziquantel 600 mg is an oral antiparasitic tablet used to treat schistosomiasis and liver fluke infections; dosing is weight-based and typically given in divided doses on a single day with food. Use requires caution in moderate–severe liver impairment, with avoidance alongside strong CYP3A inducers like rifampicin, and it is contraindicated in ocular cysticercosis.
