Platelets do not recover after chemotherapy for leukemia can generally be treated with medication, anti-leukemia therapy, platelet transfusion, dietary adjustments and other methods. 1. Drug treatment: if platelet recovery after chemotherapy is slow, platelet-raising drugs can be used under the guidance of doctors, such as platelet receptor agonists to promote platelet recovery, such as Eltrombopag olamine tablets. 2. Anti-leukemia treatment: If the effect of leukemia chemotherapy is not good, the normal hematopoietic function has not been restored, and normal platelets can not be produced, therefore, anti-leukemia treatment should be actively carried out, for example, adjusting the chemotherapy regimen or undergoing bone marrow transplantation. Drugs include decitabine, azacitidine and so on. 3. Platelet transfusion: Platelet transfusion can also help restore platelets. 4. Dietary adjustments: Diet should be high in protein, nutritionally balanced and easily absorbed. Although dietary adjustment diet can not directly elevate platelets, chemotherapy will lead to nausea, vomiting and other symptoms, which will easily cause insufficient nutritional intake, which will directly affect the ability to tolerate chemotherapy and the recovery of the disease. If the platelets do not recover after chemotherapy for leukemia, you should bring the lab results for follow-up in time and carry out standardized treatment under the doctor’s guidance.
