Ceragyn Uterine Infuse is a liquid formulation supplied in a 2 oz bottle for intrauterine use in mares as part of a breeding management program. The formula is built around a proprietary broad-spectrum compound known as Purifect Technology, combined with polysorbate, hydroxyethylcellulose, a saline base, and lactic acid. It is designed as a non-antibiotic option, so repeated administration is not associated with the yeast overgrowth that can accompany some conventional rinses. The full contents of the bottle are drawn into a sterile syringe and delivered into the uterus using a sterile catheter or pipette, following strict aseptic technique. The solution is used within veterinary breeding protocols, including before insemination and again after ovulation until the cervix closes. It is manufactured in the United States and can be stored at room temperature, with refrigeration recommended but not required.
