Lutalyse

Description

Lutalyse Sterile Solution is a natural estrus-synchronization product approved for use in horses. Lutalyse contains a well characterized prostaglandin that occurs naturally in nearly all mammalian tissue.

Usage

Lutalyse is used to control estrus time in estrous-cycling mares. Mares treated with Lutalyse during diestrus will return to estrus within 2 to 4 days in most cases. This serves as an aid to scheduling stallions.

In difficult-to-breed mares, treatment with Lutalyse usually results in regression of the corpus lutem followed by estrus and/or ovulation.

Dosage and Administration

Side Effects

Side effects may include transient decreased body temperature and sweating. Less often increased respiratory and heart rates, ataxia, abdominal pain and lying down may occur. These side effects are generally seen within 15 minutes of administration and resolve within an hour.

Precautions

Aseptic techniques should be followed in administration to reduce the possibility of post-injection bacterial infections.

Do not administer Lutalyse in pregnant animals unless cessation of pregnancy is desired.

Do not use intravenous administration.

Women of childbearing age and persons with respiratory problems should exercise extreme caution when handling Lutalyse.

Lutalyse is ineffective when administered prior to the fifth day after ovulation.

Despite treatment, mares that terminate pregnancy after 36 days may not return to the presence of functional endometrial cups.

Mares that have either acute or subacute disorders of the vascular system, gastrointestinal tract, respiratory system or reproductive tract should not be treated with Lutalyse.

Not for use in horses intended for human consumption.

Lutalyse is FDA approved for use in horses and federal law restricts this drug to use by or on the order of a licensed veterinarian.

Check with the appropriate individual regulatory board regarding use in competition horses.
