Nelarabine (Atriance) is an intravenous medication used to treat relapsed or refractory T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL). Due to its specific indications and potential severe neurotoxicity (such as coma, seizures, etc.), its purchase and use must strictly follow medical guidance.

How to Purchase Nelarabine (Atriance)

Overseas Purchase

Patients may choose to consult and purchase nelarabine at hospital pharmacies or licensed drugstores in countries or regions where the drug has been launched.

Since drug prices may be affected by factors such as regional differences and exchange rate fluctuations, patients need to make a budget and plan in advance before purchasing.

Purchase Through Medical Service Institutions

Patients can consult domestic overseas medical service institutions that cooperate with international pharmacies or pharmaceutical companies.

These institutions usually provide legal import channels and can offer professional consultation and guidance.

Precautions for Purchasing Nelarabine (Atriance)

Strictly Follow Doctor’s Instructions

The adult dose is 1500mg/m² (intravenous infusion on Days 1, 3, and 5), and the pediatric dose is 650mg/m² (continuous infusion for 5 days). The dose must be calculated based on body weight and body surface area.

The medication must be administered on an empty stomach (fasting for 1 hour before infusion or 2 hours after infusion) to avoid affecting its efficacy.

Monitor for Neurotoxicity

Nelarabine may cause severe neurological adverse reactions (such as peripheral neuropathy, drowsiness, seizures).

If symptoms such as numbness in hands and feet, difficulty walking, or confusion occur, discontinue the medication immediately and seek medical attention.

Contraindications and Drug Interactions

Concomitant use with adenosine deaminase inhibitors (e.g., pentostatin) should be avoided, as this may reduce the efficacy of nelarabine.

The drug is contraindicated in pregnant women, and patients of childbearing age must use effective contraceptive measures.

Cold Chain and Storage Requirements

Nelarabine should be stored at 20°C–25°C, and its transportation must comply with cold chain standards.

When purchasing, check whether the packaging is intact and whether there is a temperature recording label.
