Synanthic (oxfendazole) dewormer, for use in beef cattle and female dairy cattle prior to breeding age, is a low-dose internal parasiticide that controls a broad range of economically important parasites. The product is available in two formulations: a prescription 22.5 percent suspension that can be administered orally using a standard drenching gun or intraruminally with the Synanthic Rumen Injector, and a liquid 9.06 percent suspension administered orally using a standard drenching gun. There are no contraindications specified on the FDA-approved labeling. Cattle must not be slaughtered until seven days after treatment. Because a withdrawal time in milk has not been established, Synanthic should not be used in female dairy cattle of breeding age.
