No matter what your patients are focused on, PROZINC is the ideal insulin choice that meets their individual needs. That’s because PROZINC puts diabetic cats fi rst with e cacy proven to improve clinical signs,1 a duration of action appropriate for felines,2,3 and expert veterinary support. Plus, PROZINC is the only veterinary insulin recommended by the AAHA for the initial treatment of diabetic cats.3 Make PROZINC your fi rst choice. Visit PROZINC.us. Important Safety Information: For use in cats only. Animals presenting with severe ketoacidosis, anorexia, lethargy, and/or vomiting should be stabilized with short-acting insulin and appropriate supportive therapy until their condition is stabilized. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential to attain and maintain adequate glycemic control and to prevent associated complications. Overdosage can result in profound hypoglycemia and death. Progestogen and glucocorticoid use should be avoided. PROZINC insulin is contraindicated in cats during episodes of hypoglycemia and in cats sensitive to protamine zinc recombinant human insulin or any other ingredients in the PROZINC product.
