Helpful Tips:

OSPHOS is administered at 1.8 mg/kg by intramuscular injection up to a maximum dose of 900 mg per horse (one vial). Divide the total volume evenly into three separate injection sites. Discard unused vial contents. OSPHOS is provided in a single use vial and does not contain a preservative. If there is no response to initial therapy, the horse should be re-evaluated. For horses that initially respond to OSPHOS but do not maintain their clinical improvement for 6 months, OSPHOS may be re-administered at 3 to 6 month intervals based on recurrence of clinical signs. For horses that respond to OSPHOS and maintain clinical improvement for 6 months, OSPHOS should be re-administered after clinical signs recur.
