Rx Factrel (gonadorelin) Injection for Cattle, 50 mcg/mL

Rx FACTREL®

FACTREL® is a prescription gonadorelin injection used in cattle for the treatment of ovarian follicular cysts and, in combination with LUTALYSE® (dinoprost tromethamine injection), synchronization of estrous cycles in lactating dairy cows for fixed-time artificial insemination (FTAI). For ovarian follicular cyst treatment, FACTREL is indicated for lactating dairy cows, beef cows, and replacement dairy and beef heifers. Treatment helps reduce the number of days to first estrus. When used with LUTALYSE, FACTREL is part of a treatment program designed to coordinate estrous cycles and facilitate scheduled breeding.

• Ovarian cyst treatment: Indicated for treatment of ovarian follicular cysts in dairy and beef cows and replacement heifers.
• Breeding synchronization: Used with LUTALYSE to synchronize estrous cycles in lactating dairy cows for fixed-time artificial insemination.
• Active ingredient: Gonadorelin, a hormone used in reproductive management.
• Concentration: 50 mcg gonadorelin per mL, as gonadorelin hydrochloride.

Dosage & Administration:

Administer by intramuscular (IM) injection. Follow the appropriate treatment protocol for the intended use. Ovarian follicular cyst treatment:

• Administer 2 mL as a single intramuscular injection.
