DOSAGE AND ADMINISTRATION: Administer 1 teaspoon (5 mL) for each 10 lb of body weight. 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 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 T. canis reinfestation.

RECOMMENDED STORAGE: STORE BELOW 30°C (86°F).

INDICATIONS AND USAGE: LIQUI-VICT 2X suspension is a highly palatable formulation intended as a single treatment 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.

PRECAUTIONS: THIS PRODUCT IS A SUSPENSION AND AS SUCH WILL SEPARATE. TO ENSURE UNIFORM RESUSPENSION AND TO ACHIEVE
PROPER DOSAGE, IT IS EXTREMELY IMPORTANT THAT THE PRODUCT BE SHAKEN THOROUGHLY BEFORE EVERY USE.

KEEP OUT OF REACH OF CHILDREN

DOSAGE AND ADMINISTRATION: Administer 1 teaspoon (5 mL) for each 10 lb of bodyweight. 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 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 T. canis reinfestation.

SAFETY AND EFFICACY STUDIES: Critical (worm count) studies in dogs demonstrated that pyrantel pamoate at the recommended dosage is highly efficacious against T. leonina (99%), T. canis (85%), A. caninum (97%), and U. stenocephala (94%).

One of the most outstanding and significant features of pyrantel pamoate is its wide margin of therapeutic safety in dogs. The acute oral LD(50) of pyrantel pamoate administered in gelatin capsules to female and male dogs is greater than 314 mg base per lb of body weight, which indicates a therapeutic index in excess of 138 times

the recommended dosage. In subacute and chronic studies, no significant morphological abnormalities could be attributed to pyrantel pamoate when administered to dogs at daily dose rates up to 94 mg base per pound of body weight (40x) for periods of 19, 30, and 90 days. Clinical studies conducted in a wide variety of geographic locations using more than 40 different breeds of dogs showed no drug-induced toxic effects. Included in these studies were nursing pups, weaned pups, adults, pregnant bitches, and males at stud.

Additional data has demonstrated the safe use of pyrantel pamoate in dogs having heartworm infestations and/or receiving medication for heartworms, dogs exposed to organophosphate flea collars or flea/tick-dip treatments, and dogs undergoing concurrent treatment or medication at the time of worming such as immunization and antibacterial treatment.

RECOMMENDED STORAGE: STORE BELOW 86° F (30° C). Keep LIQUI-VICT 2X in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.

HOW SUPPLIED: LIQUI-VICT 2X is supplied in 2 fl. oz. (60 mL), 8 fl. oz. (236 mL), and 16 fl. oz. (474 mL) bottles.
