TMOZOLMIDE 250

Temozolomide 250 mg is an oral anticancer medicine used in the treatment of certain types of brain tumors. It belongs to a group of medicines called alkylating agents and works by damaging the DNA of cancer cells, which interferes with their ability to grow and multiply.

Temozolomide is particularly associated with the treatment of glioblastoma and anaplastic astrocytoma. Depending on the patient's diagnosis and treatment plan, it may be used alongside radiotherapy or as subsequent treatment under the supervision of a qualified oncologist. Current prescribing information identifies temozolomide as indicated for adults with newly diagnosed glioblastoma in combination with radiotherapy followed by maintenance treatment and for adults with anaplastic astrocytoma in specified settings. 

If you are searching for temozolomide 250 mg uses, benefits, side effects, dosage, price, precautions, or how to buy temozolomide 250 mg online, this guide provides practical information to help you understand the medicine and make informed purchasing decisions with your doctor's prescription.

What Is Temozolomide 250 mg?

Temozolomide 250 mg contains 250 mg of temozolomide and is supplied as an oral capsule by various manufacturers.

Temozolomide is classified as an alkylating drug. After administration, it undergoes chemical conversion to an active compound that can damage DNA. Cancer cells that cannot adequately repair this DNA damage may stop dividing or die.

The medicine is not designed to treat ordinary headaches, general weakness, benign brain conditions, or other common illnesses. Its use is specifically determined by the patient's cancer diagnosis and oncologist's treatment protocol.

Current U.S. prescribing information, revised in 2026, lists newly diagnosed glioblastoma and specified forms of anaplastic astrocytoma among its indications. 

Temozolomide 250 mg Uses

The primary use of temozolomide 250 mg is the treatment of certain malignant brain tumors.

Depending on the diagnosis and treatment protocol, temozolomide may be used for:

• Newly diagnosed glioblastoma, together with radiotherapy followed by maintenance treatment.
• Anaplastic astrocytoma, including specified newly diagnosed and refractory cases in adults.
• Other clinical situations when specifically determined appropriate by a specialist.

The exact indication can depend on tumor type, stage, previous treatment, molecular characteristics, and the patient's overall health.

Therefore, a patient should not interpret the availability of a 250 mg capsule as meaning that 250 mg is automatically the correct dose.

How Does Temozolomide 250 mg Work?

Temozolomide is an alkylating agent that produces DNA damage in tumor cells.

Cancer cells depend on continuous DNA replication to grow and divide. Temozolomide creates chemical changes in DNA that can interfere with this process. When the resulting DNA damage cannot be adequately repaired, the affected cancer cells may lose their ability to continue proliferating.

This mechanism helps explain why temozolomide can be useful against certain brain tumors. However, chemotherapy can also affect healthy cells, particularly rapidly dividing cells, which contributes to some of its adverse effects.

Key Benefits of Temozolomide 250 mg

1. Used against specific brain tumors

The most important benefit of temozolomide is its established role in the treatment of certain malignant brain tumors, particularly glioblastoma and anaplastic astrocytoma in appropriate adult patients. 

2. Oral capsule formulation

Temozolomide is available as an oral capsule, allowing patients to take treatment according to their prescribed chemotherapy schedule.

3. Can be incorporated into multimodal treatment

For newly diagnosed glioblastoma, temozolomide may be administered concurrently with radiotherapy and subsequently as maintenance treatment according to the prescribed protocol. 

4. Available in multiple strengths

Temozolomide is manufactured in different capsule strengths. The availability of a 250 mg strength allows oncologists to construct individualized treatment regimens, often using combinations of capsule strengths where necessary.

Temozolomide 250 mg Dosage

The dosage of temozolomide 250 mg cannot be determined simply from the capsule strength.

An oncologist may calculate the dose according to factors such as

• Type and stage of cancer
• Treatment phase
• Body-surface area
• Previous chemotherapy or radiotherapy
• Blood cell counts
• Liver and kidney function
• Other medicines
• Individual tolerance and treatment response

For example, prescribing information specifies different schedules for newly diagnosed glioblastoma and anaplastic astrocytoma. During treatment, blood counts are monitored, and doses may be withheld or modified depending on laboratory results. 

Do not use the 250 mg capsule as a standalone dosing instruction. Your oncologist may prescribe a different total daily dose or a combination of capsule strengths.

How to Take Temozolomide 250 mg

Follow the exact instructions provided by your oncology team.

Current Indian product information for several temozolomide 250 mg products states that they should generally be taken on an empty stomach and at the same time each day, according to the prescribed schedule. 

Swallow the capsule as directed. Do not open, chew, or crush it unless your healthcare professional specifically instructs you to do so.

If you vomit after taking the medicine or miss a scheduled dose, contact your oncology team for instructions rather than automatically taking another capsule.

Temozolomide 250 mg Side Effects

Because temozolomide is a chemotherapy medicine, it can cause side effects. The type and severity vary between patients.

Commonly reported or listed effects include:

• Nausea
• Vomiting
• Constipation
• Headache
• Fatigue or weakness
• Reduced appetite
• Hair loss in some patients
• Reduced blood cell counts
• Increased susceptibility to infections

Current Indian product information for temozolomide 250 mg products specifically identifies nausea, vomiting, constipation, headache, and fatigue among common side effects and notes that the medicine can reduce blood cell counts. 

Important Serious Side Effects and Warnings

One of the most important concerns with temozolomide is myelosuppression, meaning suppression of bone-marrow activity and reduced production of blood cells.

Low white blood cell counts can increase infection risk, while low platelet counts can increase the risk of bleeding. This is why complete blood counts are an important part of treatment monitoring.

The current prescribing information also contains warnings concerning hepatotoxicity, Pneumocystis pneumonia, secondary malignancies, and embryo-fetal toxicity. 

Contact your medical team urgently if you experience symptoms such as:

• Fever or signs of infection
• Unusual or persistent bleeding
• Severe weakness
• Shortness of breath
• Severe or persistent vomiting
• Yellowing of the skin or eyes
• Other sudden or serious symptoms

Do not wait for the next scheduled appointment if a potentially serious reaction occurs.

Temozolomide 250 mg and Blood Tests

Regular blood testing is a critical component of temozolomide treatment.

Current prescribing information recommends monitoring blood counts before and during treatment and provides specific thresholds for treatment initiation and dose modification. For concomitant radiotherapy, CBC monitoring is recommended before treatment and weekly; during 28-day maintenance cycles, monitoring is performed at specified points and more frequently when counts are low. 

This monitoring helps the oncologist determine whether treatment can continue safely or whether a dose adjustment or treatment interruption is necessary.

Pregnancy and Breastfeeding Precautions

Temozolomide can cause fetal harm. Current prescribing information advises against breastfeeding during treatment and includes specific precautions concerning pregnancy and reproductive potential. 

Patients who are pregnant, planning pregnancy, or who could become pregnant should discuss this with their oncologist before treatment.

Men and women receiving chemotherapy should also discuss fertility preservation and contraception with their healthcare team where relevant.

Temozolomide 250 mg Price in India

The temozolomide 250 mg price can vary substantially between brands, manufacturers, pack sizes, sellers, and discounts.

Recent Indian listings illustrate this variation. For example, listings updated in late August and early September 2026 show different prices for Temzol 250, Temodal 250 mg, Temorel 250, and other temozolomide 250 mg products. Some products are substantially less expensive than others, so price comparisons should always account for the same strength and pack size.

A lower price does not automatically mean a product is better, and a higher-priced brand is not necessarily more effective. For chemotherapy medicines, authenticity, correct formulation, prescription compliance, and appropriate medical supervision are more important than price alone.

Why a Prescription Matters When Buying Temozolomide 250 mg

Temozolomide is not an appropriate medicine for self-treatment.

The correct treatment schedule may involve specific chemotherapy cycles, radiotherapy, anti-nausea medicines, infection prevention, and regular laboratory monitoring. The oncologist may also change the dose according to blood counts and treatment tolerance.

For this reason, purchasing temozolomide 250 mg online should be viewed as a prescription fulfillment process rather than an ordinary OTC purchase.
