E-SE® Injection is recommended for the control of the following clinical signs when associated with myositis (selenium-Tocopherol Deficiency) syndrome: rapid respiration, profuse sweating, muscle spasms and stiffness and elevated SGOT.
Intravenous administration if elected should be by slow injection. Selenium is toxic if administered in excess. Anaphylactoid reactions, some of which have been fatal, have been reported in horses. Medications which have been reported to cause major adverse reactions in horses should be avoided when E-SE is administered. Not to be used in horses intended for food. For complete product information please see package insert.
Slow intravenous injection (see product label for warnings) or deep intramuscular injections, in divided doses, in two or more sites.
1 mL per 100 pounds of body weight. May be repeated at 5-10 day intervals.
CAUTION Intravenous administration, if elected, should be by slow injection. Emulsions injected intramuscularly into the horse may produce transitory local muscle soreness and can be prevented to some degree by injecting deeply (2 to 2 1/2 inches), in divided doses, in two or more sites. Do not continue therapy in horses demonstrating such sensitivity. selenium is toxic if administered in excess. A fixed dose schedule is therefore important (read package insert for each selenium-tocopherol product carefully before using).
WARNINGS Anaphylactoid reactions, some of which have been fatal, have been reported in horses administered E-SE Injection. Signs include excitement, sweating, trembling, ataxia, respiratory distress, and cardiac dysfunction. These reactions have been reported as association both with intravenous and intramuscular injections. It is presently unknown whether the mode of application affects the frequency of such reactions. However, reactions associated with intramuscular injections have been reported to manifest more slowly and hence may give more time to institute treatment for anaphylaxis, such as epinephrine and/or corticosteroid injection. Medications which have been reported to cause major adverse reactions in horses should be avoided when E-SE is administered, unless the condition of the animal requires such use. Not to be used in horses intended for food.
PRECAUTIONS selenium-Tocopherol Deficiency (STD) syndrome produces a variety and complexity of symptoms often interfering with a proper diagnosis. Even in selenium deficient areas there are other disease conditions which produce similar clinical signs. It is imperative that all these conditions be carefully considered prior to treatment of STD syndrome. Serum selenium levels, elevated SGOT, and creatine levels may serve as aids in arriving at a diagnosis of STD, when associated with other indices.
