Elitek reduces high uric acid levels caused by certain cancer therapies. If you have G6PD deficiency or are of African or Mediterranean descent, you may need a dose adjustment or special tests.
Elitek is a prescription medication used to reduce high uric acid levels in adults and children with leukemia, lymphoma, and solid tumor malignancies who are receiving chemotherapy medications.
When cancer cells are destroyed by chemotherapy, certain substances are released. As the body breaks these substances down, uric acid levels increase and may be harmful. Elitek is in a class of medications called urate oxidase enzymes. It works by breaking down uric acid so that the body can eliminate it.
This medication comes in an injectable form to be given directly into a vein (IV) once daily for up to 5 days.
Common side effects include nausea, vomiting, anxiety, and stomach pain.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
Elitek and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if Elitek crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using this medication.
