Chlorhexidine solution and chlorhexidine solution scrub have many uses in the horse stable. Chlorhexidine solution is a topical antiseptic containing 2% chlorhexidine acetate in an aqueous or detergent base. Given its wide range of activity, low systemic absorption, low systemic toxicity and a longer residual effect than other similar products, it is prescribed by veterinarians for many situations involving bacterial infections.


Chlorhexidine solution is the antiseptic of choice for many veterinarians for disinfecting the navels of foals. Chlorhexidine solution is often used as an anti-bacterial cleansng agent in the treatment and prevention of acute and chronic otitis externa, which is an ear infection often accompanied with inflammation. It is used as an oral cleansing solution in cases of gum inflammation and periodontal disease. Chlorhexidine is also used in the treatment of skin conditions, such as hot spots or acute dermatitis.

Chlorhexidine solution scrub is used to clean the perineal area and vulva of mares prior to breeding and also in obstetrical procedures.
