Liquid Wormer for Puppies & Dogs


(pyrantel pamoate)

Active Ingredient

2.27mg of pyrantel base as pyrantel pamoate per mL.

Liquid Wormer Indications

For the removal of large roundworms (Toxocara canis and Toxascaris leonina) and hookworms (Ancylostoma caninum and Uncinaria stenocephala) in dogs and puppies. The presence of these parasites should be confirmed by laboratory fecal exam. Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism.

Pyrantel Pamoate Liquid Wormer may also be used to prevent reinfestation of Toxocara canis in puppies and adult dogs and in lactating bitches after whelping.

Directions For Use

Administer 1 full teaspoon (5 mL) for each 5 lb of body weight. To assure proper dosage, weigh animal prior to treatment. It is not necessary to withhold food prior to or after treatment. Dogs usually find this dewormer very palatable and will lick the dose from the bowl willingly. If there is reluctance to accept the dose, mix in a small quantity of dog food to encourage consumption. It is recommended that dogs maintained under conditions of constant exposure to worm infestation should have a follow-up fecal exam within 2-4 weeks after first treatment. If your dog looks or acts sick, consult your veterinarian before treatment. For maximum control and prevention of reinfestation, it is recommended that puppies be treated at 2, 3, 4, 6, 8 and 10 weeks of age. Lactating bitches should be treated 2-3 weeks after whelping. Adult dogs kept in heavily contaminated quarters may be treated at monthly intervals to prevent Toxocara canis reinfestation.
