LUTALYSE® HighCon Injection (dinoprost tromethamine injection)

LUTALYSE® HighCon Injection (dinoprost tromethamine injection) is a high-concentration formula of LUTALYSE® Injection (dinoprost injection), the most veterinarian prescribed and producer used prostaglandin in the market.1 LUTALYSE HighCon allows for a 2-mL dose for convenience and flexibility in artificial insemination synchronization programs.

LUTALYSE HighCon is approved for use with Eazi-Breed CIDR® Cattle Inserts in heifers and cows to improve breeding efficiency and pregnancy success. It’s important to note that LUTALYSE HighCon is approved for use in cattle only, not equine or swine like LUTALYSE.  

At Zoetis, we understand the changing needs of today’s cattle producers and veterinarians. We are committed to developing solutions, including multiple Food and Drug Administration (FDA)- approved estrous synchronization options. Our focus is on you and increasing the reproductive efficiency of your herd. Improved breeding efficiency leads to a shorter calving season and a more uniform set of calves. 

Collapse All
  • LUTALYSE HighCon is:

    • Approved for a convenient 2-mL dose
    • The first-to-market prostaglandin with an FDA-approved subcutaneous claim in addition to intramuscular administration
      • Now producers and veterinarians have flexible options for route of administration consistent with strict Beef Quality Assurance (BQA) standards and Dairy Animal Care and Quality Assurance (DACQA).
    • Available in three bottle sizes, allowing choices that best fit management needs for handling and administration
      • 20-mL vial contains 10 doses
      • 100-mL vial contains 50 doses
      • 250-mL vial contains 125 doses
    • An entirely natural prostaglandin
    • Free from a requirement of meat or milk withdrawal
    • Useful therapeutically for controlled breeding

    A synchronized breeding program with LUTALYSE HighCon and FACTREL can:

    • Improve pregnancy rates
    • Reduce time necessary for heat detection
    • Make more efficient use of labor
    • Reduce cull rates


  • Effective in animals having a functional corpus luteum in the following applications:

    • For estrous synchronization, inject 2 mL LUTALYSE HighCon subcutaneously (subQ) or intramuscularly (IM) either once or twice at 10- to 12-day intervals.
    • For treatment of unobserved estrus, inject a 2-mL dose subQ or IM. If estrus has not been observed by 80 hours after injection, breed at 80 hours; if the cow returns to estrus, breed at the usual time relative to estrus.
    • For postpartum treatment of pyometra, inject a dose of 2 mL subQ or IM at signs of pyometra (presence of a corpus luteum on the ovary and uterine horns containing fluid but not a conceptus based on palpation).
    • LUTALYSE HighCon is approved for use in cattle only, not equine or swine like LUTALYSE.
