Abitrexate (PF) Inj

In Depth

Lumps (tumors/abnormal growths) may very infrequently appear during methotrexate use. The drug must be stopped and treatment may be needed. Consult your doctor immediately if new lumps/growths occur.

When used to treat tumors, methotrexate sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). Tell your doctor immediately if you experience symptoms such as irregular heartbeat or muscle weakness.

Although rare, this medication when used with radiation treatment may increase the risk of tissue and bone damage. Discuss the risks and benefits of your treatment plan with your doctor.
