DIRECTIONS: Administer orally. In beef and dairy cattle, the recommended dose of 2.3 mg/lb (5 mg/ kg) is achieved when 2.3 mL of the drug are given for each 100 lb of body weight. In beef cattle only, the recommended dose of 4.6 mg/lb (10 mg/kg) for treatment and control of Type II Ostertagiasis (4th stage inhibited larvae) or tapeworms is achieved when 4.6 mL of the drug is given for each 100 lb of body weight. EXAMPLES:

Cattle Weight	Dose (2.3 mg/lb)	Dose 4.6 mg/lb
100 lb	2.3 mL	4.6 mL
200 lb	4.6 mL	9.2 mL
300 lb	6.9 mL	13.8 mL

1500 lb	34.5 mL	69.0 mL

Do not underdose. Ensure each animal receives a complete dose based on a current body weight. Underdosing may result in ineffective treatment, and encourage the development of parasite resistance.

WARNINGS: NOT FOR USE IN HUMANS. KEEP OUT OF REACH OF CHILDREN. The Safety Data Sheet (SDS) contains more detailed occupational safety information. For customer service, adverse effects reporting, and/or a copy of the SDS, call 1-800-211-3573. For additional information about adverse drug experience reporting for animal drugs, contact FDA at 1-888-FDAVETS, or http://www.fda.gov/reportanimalae.

OTHER WARNINGS: Parasite resistance may develop to any dewormer, and has been reported for most classes of dewormers. Treatment with a dewormer used in conjunction with parasite management practices appropriate to the geographic area and the animal(s) to be treated may slow the development of parasite resistance. Fecal examinations or other diagnostic tests and parasite management history should be used to determine if the product is appropriate for the herd, prior to the use of any dewormer. Following the use of any dewormer, effectiveness of treatment should be monitored (for example, with the use of a fecal egg count reduction test or another appropriate method). A decrease in a drug's effectiveness over time as calculated by fecal egg count reduction tests may indicate the development of resistance to the dewormer administered. Your parasite management plan should be adjusted accordingly based on regular monitoring.

Store at or below 25°C (77°F). Protect from freezing. Shake well before use.
