Directions for Use: Use in well-ventilated areas or outdoors. Close container tightly when not in use. Cattle should not be treated when hair or hide is wet since reduced efficacy may be experienced. Do not use when rain is expected to wet cattle within six hours after treatment. This product is for application to skin surface only. Do not give orally or parenterally. Dosage: The dose rate is 1 ml for each 22 lb of body weight. The formulation should be applied along the topline in a narrow strip extending from the withers to the tailhead. Each 5 ml will treat 110 lb body weight. When body weight is between marking, use the next higher 5 ml increment. Ivermectin Pour-On (generic) for Cattle controls horn flies Haematobia irritans for up to 28 days after dosing. For best results, Ivermectin Pour-On (generic) for Cattle should be part of a parasite control program for both internal and external parasites based on the epidemiology of these parasites. Consult your veterinarian or an entomologist for the most effective timing of applications. Ivermectin Pour-On (generic) for Cattle effectively controls all stages of cattle grubs. However, proper timing of treatment is important. For the most effective results, cattle should be treated as soon as possible after the end of the heel fly (warble fly) season. While this is not peculiar to ivermectin, destruction of Hypoderma larvae (cattle grubs) at the period when these grubs are in vital areas may cause undesirable host-parasite reactions. Killing Hypoderma lineatum when it is in the esophageal tissues may cause bloat; killing H. bovis when it is in the vertebral canal may cause staggering or paralysis. Cattle should be treated either before or after these stages of grub development. Cattle treated with Ivermectin Pour-On (generic) for Cattle at the end of the fly season may be re-treated with Ivermectin Pour-On (generic) for Cattle during the winter without danger of grub-related reactions. For further information and advice on a planned parasite control program, consult your veterinarian. Residue information Cattle must not be treated within 48 days of slaughter for human consumption. Because a withdrawal time in milk has not been established, do not use in female dairy cattle of breeding age. A withdrawal period has not been established for this product in pre-ruminating calves. Do not use in calves to be processed for veal. Environmental Safety Studies indicate that when ivermectin comes in contact with the soil, it readily and tightly binds to the soil and becomes inactive over time. Free ivermectin may adversely affect fish or certain aquatic organisms. Do not permit cattle to enter lakes, streams or ponds for at least six hours after treatment. Do not contaminate water by direct application or by the improper disposal of drug containers. Dispose of containers in an approved landfill or by incineration.
