Reserpine is used as a long-acting sedative for horses and is frequently prescribed to horses with existing injuries that require a slow recovery plan. A low dose sedative can aid in keeping the horse calm during stall rest to prevent re-injury or additional damage.
Reserpine should only be used when prescribed by a veterinarian with specific dosing instructions for the individual horse and situation. While this medication is useful for horses recovering from an injury, there are potential side effects that should be carefully monitored. Horses could have an allergic reaction to this product resulting in facial swelling, hives, itching, shock, seizures, pale gums, and cold limbs. Other side effects include colic, GI upset, diarrhea, and lower limb swelling. If any of these signs are present, owners should discontinue use and contact their veterinarian.
