The Effects of Tylan

Tylan is a brand name of the drug Tylosin. It is used as both an anti-inflammatory and as an antibiotic. Tylan is often used in livestock animals such as cattle, and to a lesser extent, in dogs. Tylan is not labeled by the FDA for use in small animals, but it may be used legally when prescribed by a veterinarian. It is available in oral powder, a chewable tablet and as an injectable liquid.

  1. Use in Large Animals

    • Tylan is a common addition to the diet of livestock. It helps prevent and treat bacterial infections, including respiratory tract and skin infections. Tylan also encourages growth in food livestock.

    Use in Small Animals

    • According to the Pet Place Drug Library, Tylan can treat small intestinal bacterial overgrowth in dogs. It can also treat inflammation of the colon (colitis) in cats. Tylan is also used to treat epiphora in some dogs. Epiphora occurs when a dog's tear ducts overproduce tears, and the constant flow stains the fur below the eye. For this use, the drug is marketed under the name Angel Eyes.

    Side Effects

    • Gastrointestinal problems are common with Tylan usage, especially after oral administration. Diarrhea is a prominent side effect. Skin itching is another side effect associated with Tylan. Tylan administered by intramuscular or subcutaneous injection can result in swelling and redness at the injection site. Tylan usage can result in elevated ALT and AST (liver enzymes) levels in blood tests.
