Wear impermeable latex or nitrile gloves, protective glasses and a laboratory coat when applying ZORBIUM. Following application to the cat, allow a minimum drying time of 30 minutes before direct contact with the application site.

Do not apply ZORBIUM if the application site at the dorsal cervical area has diseased or injured skin, or to anatomic areas other than the dorsal cervical area because absorption characteristics may be different. Body temperature should be monitored postoperatively. Most common adverse reactions during anesthesia were hypothermia, hypotension and hypertension, and after anesthetic recovery were hypothermia, hyperthermia and sedation. The safe use of ZORBIUM has not been evaluated in debilitated cats; those with renal, hepatic, cardiac or respiratory disease; pregnant, lactating or breeding cats; in cats younger than four months old; or in cats <2.6 lbs. or >16.5 lbs.
