What is Temozolomide (Temodar) used for?

How Temozolomide (Temodar) works

Temozolomide (Temodar) is a type of traditional chemotherapy. It’s known as an alkylating agent.

Once temozolomide (Temodar) gets inside a cancer cell, it attaches to the cell’s DNA. This damages the DNA, which usually causes the cancer cell to die. As a result, the cancer cell can’t make copies of itself so the cancer can’t grow.

Pharmacist tips for Temozolomide (Temodar)

pharmacist

  • You might need to take an antibiotic like Bactrim (sulfamethoxazole / trimethoprim) during treatment. This helps prevent you from getting a lung infection. You’re more likely to need it if you're taking temozolomide (Temodar) with radiation or if your white blood cell count is low.

    • Temozolomide (Temodar) can cause nausea and vomiting. Your oncologist might give you antiemetics like ondansetron (Zofran) or prochlorperazine to help. They might tell you to take them before each temozolomide (Temodar) dose. You can also take them between doses if you feel nauseous. If this side effect bothers you too much, talk to your care team.

      • Temozolomide (Temodar) can put you at risk of getting sick. So, take your temperature often, like once a day. Call your care team right away if it’s 100.4ºF or higher — this means you have a fever. It can sometimes be the only sign that you’re sick, so it’s important to let your oncologist know as soon as possible.

        Tips for temozolomide (Temodar) capsules:

        • Take temozolomide (Temodar) at the same time each day so it works the best it can for you. It also helps you remember to take your medication by making it a part of your daily routine.

          • You can take temozolomide (Temodar) with or without food. But it’s a good idea to take it on an empty stomach or at bedtime. This helps reduce nausea and vomiting.

            • Swallow temozolomide (Temodar) capsules whole with water. Don’t crush, open, or chew them because the powder inside can be irritating and harmful.

              • If a temozolomide (Temodar) capsule gets damaged, avoid getting the powder on your skin, in your eyes, or in your nose. Wash the area with water right away if this happens though.

                • Ask your oncologist if you’re not sure about your temozolomide (Temodar) dose. This includes which capsule strength to take and how many to take. Temozolomide (Temodar) capsules come in different strengths, and you might need to take more than one at a time. Your dose might change during treatment depending on how you tolerate the medication.

                  • Ask your oncology team about the best way to handle and throw away temozolomide (Temodar) safely. Anticancer medications can be harmful to people who handle or come in contact with them. Keep the medication in a safe place away from children and pets.

                    Tips for temozolomide (Temodar) IV infusion:

                    • Plan ahead for some time at the medical center or infusion center for your temozolomide (Temodar) IV infusion. The infusion itself lasts about an hour and a half. But you might need some extra time to do paperwork or get situated. Bring something to do, like a book to read or an electronic device, to help pass the time.

                      • You might have a reaction where you get your temozolomide (Temodar) IV infusion. You might feel pain, irritation, itchiness, and warmth around the area. There also could be swelling, redness, and bruising. Tell your nurse or oncology team if this happens and it bothers you. They can help manage these injection site reactions.

                        Frequently asked questions about Temozolomide (Temodar)

                        What cancer is temozolomide (Temodar) used for?
                        Temozolomide (Temodar) is FDA approved to treat two types of brain cancer: glioblastoma and anaplastic astrocytoma. But it’s also sometimes used off-label to treat other types of cancer. This includes certain types of neuroendocrine tumors and sarcoma. Talk to your oncologist to see if temozolomide (Temodar) is right for your cancer.
                        Is temozolomide (Temodar) chemotherapy?
                        Yes, temozolomide (Temodar) is a type of traditional or standard chemotherapy. It works by killing fast-growing cells, including cancer cells, by damaging their DNA. It stops cancer cells from spreading. But the medication can also affect healthy fast-growing cells, like the ones in your stomach and hair. That’s why nausea and hair loss are common side effects of temozolomide (Temodar).
                        Do I need to take an antibiotic while I’m taking temozolomide (Temodar)?
                        It depends on your risk of getting a specific lung infection called Pneumocystis pneumonia (PCP). Some people taking temozolomide (Temodar) have a higher risk. This includes people getting radiation at the same time and those with a low lymphocyte count (a type of white blood cell). If you’re at high risk, your oncologist might recommend an antibiotic to help prevent PCP. The most common one is Bactrim (sulfamethoxazole / trimethoprim). But there are other options if you’re allergic to sulfa drugs. Ask your oncologist if you need to take an antibiotic while taking temozolomide (Temodar). Follow their instructions if you do.
                        Does temozolomide (Temodar) cause hair loss?
                        Some people taking temozolomide (Temodar) can have hair loss. Typically, your hair will grow back after you stop taking the medication. Let your care team know if you notice hair loss or shedding during treatment. They can talk to you about ways to manage this side effect, such as using a soft brush or a cooling cap.
                        How long does temozolomide (Temodar) stay in your system?
                        A single dose of temozolomide (Temodar) stays in your body for about 9 hours. This is based on the medication’s half-life, which is how long it takes the body to break it down. Ask your oncologist if you have more questions about how long temozolomide (Temodar) stays in your system.
                        Is it safe to take temozolomide (Temodar) while pregnant?
                        If you or your partner becomes pregnant while you’re taking temozolomide (Temodar), tell your oncologist right away. We don’t know how temozolomide (Temodar) affects people who are pregnant because there aren’t any studies done about this. But animal studies show that it might harm an unborn baby. Your oncologist can talk to you about the safest treatment options for you.
                        Can you breastfeed while taking temozolomide (Temodar)?
                        You shouldn’t breastfeed while taking temozolomide (Temodar) and for 1 week after your last dose of the medication. We don’t know if temozolomide (Temodar) passes into human milk. But because of the way the medication works, it might be harmful to your baby if it does. Talk to your oncologist or a lactation specialist about your options.

                        What are the risks and warnings for Temozolomide (Temodar)?

                        Temozolomide (Temodar) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                        risk-warning

                        Low blood cell count

                        • Risk factors: Older adults | Female

                          Taking temozolomide (Temodar) can cause your blood cell counts to drop. This can put you at higher risk for infections, anemia, and easy bleeding. Sometimes, it can be very serious.

                          Your oncologist will check your blood cell counts before each cycle and occasionally during treatment. If your blood cell count gets too low, your oncologist might lower your dose or pause your treatment until it goes back up.

                          During treatment, watch for signs of infection like fever, chills, or cough. Also look out for signs of anemia, such as feeling tired or having pale skin. And tell your care team if you bleed or bruise more easily than usual.

                          risk-warning

                          Serious liver problems

                          • Risk factors: History of liver problems

                            Although uncommon, serious liver problems can happen in some people taking temozolomide (Temodar). Sometimes, it can be life-threatening.

                            Your oncologist will regularly check your liver health with lab tests. So, be sure to go to all the lab appointments your oncologist recommends. Tell your care team if you have belly pain, a swollen belly, yellow skin, or yellow eyes during treatment. These could be signs of liver damage.

                            risk-warning

                            Pneumonia

                            • Risk factors: Also taking corticosteroids | Taking temozolomide (Temodar) together with radiation | Taking temozolomide (Temodar) for a long time

                              Some people taking temozolomide (Temodar) have gotten a lung infection called Pneumocystis pneumonia (PCP). Your risk is higher if you’re also taking a corticosteroid like dexamethasone. It’s also higher if you’re getting radiation at the same time. Your oncologist might prescribe an antibiotic to help prevent this infection. A common one used is Bactrim (sulfamethoxazole / trimethoprim).

                              Tell your care team if you have a fever, cough, trouble breathing, chest pain, chills, or feel very tired while taking temozolomide (Temodar). These can be symptoms of PCP.

                              risk-warning

                              Risk of new cancers

                              People taking temozolomide (Temodar) have a higher risk of developing new cancers later. This has included cancers including acute myeloid leukemia (AML). Your oncologist will monitor for this side effect with lab tests, even after you’ve stopped taking temozolomide (Temodar). Talk to your oncologist if you’re worried about this risk.

                              risk-warning

                              Harm to an unborn baby

                              • Risk factors: Pregnancy

                                Animal studies show that temozolomide (Temodar) might harm an unborn baby or cause pregnancy loss (miscarriage). If you can get pregnant, use reliable birth control while taking this medication and for 6 months after your last dose.

                                If you’re having sex with someone who can get pregnant, also use birth control like condoms during treatment and for 3 months after stopping. Because temozolomide (Temodar) might affect sperm, don’t donate semen during this time.

                                Tell your oncologist right away if you or your partner becomes pregnant while you’re taking temozolomide (Temodar).

                                dosage

                                Most people take temozolomide (Temodar) as a capsule that’s swallowed whole. There’s also an infusion that’s given through the vein (IV) over 90 minutes at a medical center.

                                The dose is the same whether you take the capsule or get the IV. Your oncologist will calculate your dose based on your body surface area (BSA). This takes into account your height and weight.

                                • Anaplastic astrocytoma

                                  • Cycle 1: The recommended dose is 150 mg/m2 once a day on days 1 to 5 of the first 28-day cycle of treatment.

Your oncologist will decide on your dose based on your lab results and if you have any serious side effects from the medication. The dose can be even lower if you have severe side effects.
