For which conditions is this drug approved? Vistogard is approved for the emergency treatment of adults and children who have received an overdose of one of the following chemotherapy medicines: fluorouracil or Xeloda® (capecitabine). Vistogard can be used in patients with or without symptoms of an overdose or in those with early signs of the following severe or life-threatening side effects: complications that affect the heart; early signs of severe or life threatening neurologic (central nervous system) problems; or certain unusually severe side effects the occur within four days (96 hours) after receiving treatment with fluorouracil or Xeloda.

What is the mechanism of action? Overdoses of fluorouracil or Xeloda can occur when the patient receives either drug at a higher dose or rate than intended. In addition, some people have genetic variations that put them at risk of overdose; and in some, their body doesn’t clear the drug effectively, or they are especially sensitive to the drug. Vistogard works by reducing the ability of excess fluorouracil or Xeloda to harm or kill healthy cells.

How is Vistogard typically given (administered)? Vistogard comes in granules and is taken orally (by mouth). The granules come in 10-gram packets that you mix with a small amount of soft food—such as 3 to 4 ounces of applesauce, pudding, or yogurt in a small container. The full treatment of Vistogard is 20 doses.

What are the side effects (occur in 10% to 29% of patients) of treatment with Vistogard?
