How it works

Dexamethasone is a synthetic corticosteroid, which means it mimics the effects of hormones naturally produced by your adrenal glands. It works mainly by reducing inflammation and suppressing the immune system’s activity.

In blood cancers like Burkitt lymphoma, dexamethasone is often used as part of chemotherapy regimens. It helps decrease inflammation and swelling caused by cancer or its treatment, and can also reduce allergic reactions to other chemotherapy drugs. By suppressing the immune response, dexamethasone can help control symptoms such as pain, nausea, and swelling, and may also help destroy cancer cells in certain types of blood cancers.

Dexamethasone’s anti-inflammatory and immunosuppressive effects are also useful in managing side effects of cancer and its treatment, such as brain swelling (cerebral edema) or severe allergic reactions.

Who should take it

Dexamethasone is used in the palliative management of leukemias and lymphomas, including Burkitt lymphoma. It is also used to control severe inflammation, allergic reactions, and certain autoimmune conditions. In blood cancers, dexamethasone can be part of combination chemotherapy regimens to help reduce tumor burden and manage symptoms.

Patients may also receive dexamethasone to help prevent or treat side effects from other cancer treatments, such as swelling in the brain (cerebral edema), severe allergic reactions, or nausea and vomiting. The decision to use dexamethasone is individualized based on the patient’s specific diagnosis and treatment plan.

Who should not take it

Dexamethasone should not be taken by people who have:

• Systemic fungal infections
• Known hypersensitivity to dexamethasone or any of its components

Caution is also needed in patients with active or latent infections (such as tuberculosis, hepatitis B, or amebiasis), those with a history of certain eye infections (herpes simplex), or those with certain heart, kidney, or liver problems. Live vaccines should not be given while on immunosuppressive doses of dexamethasone. Always inform your doctor about your full medical history before starting dexamethasone.

Commonly used with

In the treatment of blood cancers like Burkitt lymphoma, dexamethasone is often used in combination with other chemotherapy drugs, such as vincristine, cyclophosphamide, doxorubicin, methotrexate, and cytarabine.

It may also be used with medications to prevent nausea (antiemetics), antibiotics to prevent or treat infections, and drugs to manage side effects such as pain or swelling.

Commonly tested with

Dexamethasone is commonly tested in combination with other chemotherapy agents in clinical trials for blood cancers, including Burkitt lymphoma. It is also tested with supportive care medications, such as antiemetics, antibiotics, and other corticosteroids, to evaluate the best ways to manage cancer and its side effects.

In research and clinical practice, dexamethasone may be compared or combined with other corticosteroids (like prednisone or methylprednisolone) to determine the most effective regimen for specific blood cancers.
