1. What Bortezomib Dr. Reddys is and what it is used for

This medicine contains the active substance bortezomib, a "proteasome inhibitor". Proteasomes play an important role in controlling cell function and growth. Bortezomib can destroy cancer cells by interfering with their function.

Bortezomib is used to treat multiple myeloma (a type of bone marrow cancer) in patients over 18 years of age:

• alone or with the medicines doxorubicin liposomal pegylated or dexamethasone, for patients whose disease is getting worse (in progression) after receiving at least one previous treatment and for those patients whose stem cell transplant did not work or is not suitable.
• in combination with the medicines melphalan and prednisone, for patients whose disease has not been previously treated and who are not suitable for high-dose chemotherapy before a stem cell transplant.
• in combination with the medicines dexamethasone or dexamethasone and thalidomide, in patients whose disease has not been previously treated and who receive high-dose chemotherapy before a stem cell transplant (induction treatment).

Bortezomib is used to treat mantle cell lymphoma (a type of cancer that affects the lymph nodes) in patients 18 years of age or older in combination with the medicines rituximab, cyclophosphamide, doxorubicin, and prednisone, in patients whose disease has not been previously treated and for those patients who are not considered suitable for a stem cell transplant.

2. What you need to know before you use Bortezomib Dr. Reddys

Do not use Bortezomib Dr. Reddys

• if you are allergic to bortezomib, boron, or any of the other ingredients of this medicine (listed in section 6)
• if you have certain severe lung or heart problems.

Warnings and precautions

Tell your doctor if you have:

• low red or white blood cell count
• bleeding problems and/or low platelet count in the blood
• diarrhea, constipation, nausea, or vomiting
• a history of fainting, dizziness, or lightheadedness
• kidney problems
• moderate to severe liver problems
• numbness, tingling, or pain in the hands or feet (neuropathy) in the past
• heart problems or high blood pressure

• seizures
• shingles (localized, including around the eyes, or widespread)
• symptoms of tumor lysis syndrome, such as muscle cramps, muscle weakness, confusion, vision loss, or difficulty breathing
• memory loss, changes in thinking, difficulty walking, or vision loss. These may be signs of a serious brain infection, and your doctor may advise further tests and follow-up.

You will need to have regular blood tests before and during treatment with bortezomib to check your blood cell count regularly.

You must tell your doctor if you have mantle cell lymphoma and are given rituximab together with bortezomib:

Before starting treatment with bortezomib, you should read the package leaflets of all the medicines you need to take in combination with bortezomib to find information related to these medicines.

When using thalidomide, special attention should be paid to pregnancy testing and preventive measures (see Pregnancy and Breastfeeding in this section).

Children and adolescents

Bortezomib should not be used in children and adolescents because it is not known how it will affect them.

4. Possible Adverse Effects

Like all medicines, this medicine can cause adverse effects, although not all people suffer from them. Some of these effects can be serious.

If you are administered bortezomib for multiple myeloma or mantle cell lymphoma, report immediately to your doctor if you observe any of the following symptoms:

• Confusion, loss or alteration of vision, blindness, convulsions, headaches
• Difficulty breathing, swelling of the feet or alterations in heart rhythm, high blood pressure, fatigue, fainting

The dissolution of the lyophilized powder is complete in less than 2 minutes.

The concentration of the resulting solution will be 1 milligram/milliliter. The solution should be colorless and transparent, with a final pH of 4 to 7. It is not necessary to check the pH of the solution.

1.2 Before administration, visually inspect the solution to rule out the presence of particles and color changes. If any color change or particle is observed, the solution should be discarded. Check that the correct dose is being used for administration by intravenous route(1 mg/ml).
