Product introduction

Darzalex 400mg Injection is given as an IV infusion into veins under the supervision of a doctor. Your doctor will decide what dose is necessary and how often you need to take it. This will depend on what you are being treated for and may change from time to time. You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to.

Infusion reaction such as swollen face, lips, mouth, tongue or throat, difficulty swallowing or breathing are very common side effects. This medicine may reduce the number of blood cells (decrease white blood cells) in your blood, thereby, increasing the susceptibility to infections. Regular blood tests are required to check your blood cells while taking this medicine.

Many other medicines can affect, or be affected by, this medicine so let your healthcare team know all medications you are using. This medicine is not recommended during pregnancy or while breastfeeding. Use of effective contraception by both males and females during treatment is important to avoid pregnancy.

There is a Patient Support Program/Patient Assistance Program available in India for this medicine, being managed by Tata 1mg. Please contact your prescribing doctor to know more about the same. You may also call on (1800-102-1618) for more details.

Frequently asked questions

What is Darzalex 400mg Injection used for?

Darzalex 400mg Injection is prescribed for adults with multiple myeloma (a type of cancer of plasma cells) and may be given alone or with other medicines, depending on the treatment plan and prior therapies.

What are the most important infusion-related warnings of Darzalex 400mg Injection?

Can Darzalex 400mg Injection affect blood transfusions or blood tests?

Yes, Darzalex 400mg Injection can cause a positive indirect Coombs test and interfere with matching blood for transfusions for up to six months after the last dose, so a blood type and screen is done before starting this medicine, and blood banks must be informed about current or recent treatment.

Does Darzalex 400mg Injection lower blood counts?

Darzalex 400mg Injection can reduce white blood cells (raising infection risk) and platelets (raising bleeding risk), so regular blood tests are done, and dosing may be delayed until counts recover when needed.

Can hepatitis B reactivate with Darzalex 400mg Injection?

Yes, hepatitis B can reactivate with Darzalex 400mg Injection, rarely causing severe illness. Doctors check hepatitis B status before, during, and after treatment and monitor for symptoms such as worsening tiredness or yellowing of eyes/skin.

Does Darzalex 400mg Injection change how doctors measure myeloma response?

Yes, Darzalex 400mg Injection can appear on serum protein tests (SPEP/IFE) and look like the myeloma protein, potentially masking a complete response. Specialized assays may be used to distinguish the medicine from the disease protein when needed.

Are there special cautions for breathing or eye symptoms during receiving Darzalex 400mg Injection?

People with chronic lung disease may need extra inhaled medicines in addition to receiving Darzalex 400mg Injection. Additionally, any new eye pain, blurred vision, or acute vision changes during receiving Darzalex 400mg Injection should trigger an immediate pause and urgent eye evaluation before restarting.

What should be done before starting Darzalex 400mg Injection treatment to improve safety?

Before starting Darzalex 400mg Injection, your doctor will check your blood type and hepatitis B status, plan medicines to prevent infusion reactions, and arrange regular blood count monitoring. You should also inform your doctor about any past infections, lung problems, and all medicines or supplements you’re taking.
