  • Reducine Absorbent for Horses


Reducine is a counterirritant for use as an aid in the temporary relief of minor stiffness or soreness caused by overexertion.


As a blistering agent

The principal use of Reducine is as a counterirritant. A counterirritant is a substance which creates inflammation in one location with the goal of lessening the inflammation in another location. In the case of the horse, the Reducine is applied to the skin of a sore limb, causing it to be irritated. The skin irritation reduces the sense of pain or discomfort from the underlying strained muscles.

The use of counterirritants for this purpose has largely been replaced by topical and/or systemic medications, such as phenylbutazone.

As a hoof treatment

Reducine is composed of pine tar, resublimated iodine, and potassium iodide. The black, tarry substance provides both anti-bacterial and sealant properties. Reducine may help in the treatment of mild thrush and help to maintain hoof moisture in dry conditions when applied to the frog and sole of the hoof.

As a hoof growth stimulant

Research has shown that hoof growth may be enhanced when Reducine or another similar counterirritant is applied to the coronary band of the hoof. It is thought that Reducine increases blood flow to the coronary, causing an increase in growth rate.

  • Extra-label use of drugs in treating animals is allowable only by licensed veterinarians within the context of a valid veterinarian-client-patient relationship, and does not include drug use in treating animals by the layman (except under the supervision of a licensed veterinarian).
  • The duration of administration depends on the condition being treated, response to the medication and the development of any adverse effects. Be certain to complete the prescription unless specifically directed by your veterinarian. Even if your equine appears to feel better, the entire treatment plan should be completed to prevent relapse.

Side effects

This medication will irritate the skin if over-applied. Use only a thin coat, just enough to moisten the skin. Discontinue use if the area becomes overly sensitive or blistering occurs.


Not for human use. Do not use on cats. Do not apply to mucous membranes. Not for animals intended for consumption. Seek veterinarian advice prior to use. Do not use with oil or lard as is customary after blistering. Use rubber gloves for application, or apply with a stiff brush.
