Important safety information

PRASCEND is for use in horses only. Treatment with PRASCEND may cause loss of appetite. Most cases are mild. Weight loss, lack of energy and behavioral changes also may be observed. If severe, a temporary dose reduction may be necessary. PRASCEND has not been evaluated in breeding, pregnant or lactating horses and may interfere with reproductive hormones in these horses. Using PRASCEND at the same time as drugs known as dopamine antagonists should be avoided. These drugs may diminish the effectiveness of PRASCEND. If your horse is especially sensitive to pergolide mesylate or similar products, PRASCEND should not be used. Refer to the package insert for complete product information.
