Coughing may be observed in some animals during and for several minutes following drenching.

Ivermectin (ivermectin) Sheep Drench has been formulated for use in sheep only. This product should not be used in other animal species as severe adverse reactions, including fatalities in dogs, may result.


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/flock, 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.

Keep this and all drugs out of reach of children.
Refrain from smoking and eating when handling. Avoid contact with eyes. Immediately wash hands and any spills on the skin with plenty of soap and water following use.
Restricted Drug (California) — Use Only as Directed.

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 and certain water-born organisms on which they feed. Do not permit water runoff from feedlots to enter lakes, streams, or ground water. Do not contaminate water by direct application or by the improper disposal of drug containers. Spills should be contained and soaked up with absorbent towels or into loose soil. Gloves should be worn to prevent skin exposure. All the collected materials (contaminated towels and soil), as well as all empty drug containers, should be placed in an impervious film (plastic) bag and disposed of by incineration or in an approved landfill.


Store at 68° — 77° F (20° — 25° C). Excursions between 59° — 86° F (15° — 30° C) are permitted.
