After the 1st chemotherapy for leukemia, the platelet count is normalized, no further treatment for platelet count is needed, but it is suggested that consolidation chemotherapy is needed. 1. If the platelet count is low as a result of chemotherapy for leukemia, it is necessary to use thrombopoietin, interleukin 11 or eltrombopagnes to raise the platelet count under the guidance of the doctor. After the above treatments, the platelet count can be normalized. 2. As the principle of leukemia treatment is that consolidation chemotherapy is needed after complete remission of the disease by induction chemotherapy, after the platelet count returns to normal, consolidation and intensive treatment is also needed. Specific drugs include cytarabine and zorubicin. For patients with abnormal blood counts after chemotherapy, it is recommended to consult the hematology department of regular hospitals and receive treatment under the guidance of physicians.
