Gleevec is called imatinib mesylate, and you can take antibiotics while taking imatinib mesylate, and it is more necessary to use antibiotics for anti-infection treatment if an infection occurs during the medication. Imatinib mesylate is a kind of antineoplastic drug, which can be used to treat patients with chronic granulocytic leukemia (CML) in the acute stage, accelerated stage, or chronic stage after the failure of alpha-interferon therapy, and also used to treat patients with malignant gastrointestinal mesenchymal stromal tumors (GIST) that can not be surgically resected or metastatic, and you can fight antibiotics during the medication. As the immunity of patients with chronic granulocytic leukemia will be reduced, and taking imatinib mesylate will also lead to the adverse reaction of neutropenia, which will then lead to the patient’s immunity, all these conditions will make the patient infected, so it is more necessary to use antibiotics for anti-infection treatment. If you are taking Imatinib Mesylate and have the need to take antibiotics, please consult your physician and do so under his or her guidance, do not take the medication on your own.
