Injection, asparaginase (erwinaze), 1,000 iu
HCPCS code
Name of the Procedure:
Injection of Asparaginase (Erwinaze), 1,000 IU
Common Names: Erwinaze Injection, Asparaginase Injection
Summary
Asparaginase (Erwinaze) is a medication used in chemotherapy that is administered by injection. It works by breaking down asparagine, an amino acid that certain cancer cells need to grow. By depleting asparagine, the medication can help slow down or stop the growth of these cancer cells.
Purpose
This injection is primarily used to treat acute lymphoblastic leukemia (ALL), a type of cancer affecting white blood cells. The goal is to reduce the cancer cells in the body, manage symptoms, and ultimately achieve remission.
Indications
- Acute lymphoblastic leukemia (ALL)
- Relapse or resistance to initial chemotherapy in ALL
- As part of a combination chemotherapy regimen
Preparation
- No specific fasting required
- Inform your healthcare provider about all medications and supplements you are taking
- Complete blood count (CBC) and liver function tests may be required beforehand
Procedure Description
- The procedure begins with the patient seated or lying down comfortably.
- A healthcare professional cleans the injection site with an antiseptic.
- The Erwinaze is injected either intravenously (IV) or intramuscularly (IM) using a sterile syringe.
Monitoring for any immediate reactions is conducted post-injection.
Tools/Equipment:
- Sterile syringe
- Antiseptic solution
- Erwinaze medication vial
Anesthesia/Sedation:
- Generally, no anesthesia or sedation is required unless there is high anxiety or pain involved.
Duration
The actual injection takes only a few minutes. Including preparation and monitoring, the total procedure time is usually about 20-30 minutes.
Setting

- Pancreatitis
- Liver toxicity
Management: Immediate medical attention for severe reactions; supportive care for mild symptoms.
Benefits
- Reduces the number of cancer cells
- Helps in achieving remission in ALL
- Can be a pivotal part of a multi-drug chemotherapy regimen
Realization: Benefits are often seen after a few treatment cycles, depending on individual response.
Recovery
- Monitoring for allergic reactions or side effects post-injection
- Follow-up blood tests to monitor treatment efficacy and side effects
- Generally, patients can return to normal activities shortly after unless otherwise advised
Alternatives
- Other forms of asparaginase (e.g., Pegaspargase)
- Other chemotherapy drugs like Methotrexate, Cyclophosphamide
- Radiation therapy
- Bone marrow or stem cell transplant
Pros/Cons:
- Alternatives vary in side effect profiles and effectiveness; suitability depends on individual patient condition and response.
Patient Experience
- Mild discomfort or pain at the injection site
- Possible mild side effects such as nausea or fatigue
- Anxiety which can be managed with reassurance and, if necessary, mild sedation or anti-anxiety medication
- Support and monitoring from the healthcare team to ensure comfort and safety throughout the procedure.
