The white-white injection and platelet-raising injection can be given at the same time. 1. The white-bleaching injection, i.e. recombinant human granulocyte stimulating factor injection, promotes the immature neutrophils in the human bone marrow to mature, differentiate, proliferate and converge into the peripheral blood as soon as possible, which is mostly used for cancer chemotherapy patients to avoid the myelosuppressant side effects caused by the chemotherapy drugs. 2. Platelet-boosting injections mainly include recombinant human thrombopoietin and interleukin-11. recombinant thrombopoietin, applicable to primary immune thrombocytopenia after radiotherapy or chemotherapy, especially for primary immune thrombocytopenia which is ineffective in glucocorticoid treatment, has the effect of rapidly raising platelets. All of the above drugs can cause fever, rash, diarrhea and other adverse reactions, and contraindications include severe hepatic and renal failure, and patients with allergy to drugs. Therefore, the concomitant use of white-bleeding and platelet-raising injections can be used after chemotherapy to prevent complications such as myelosuppression, but blood changes should be closely monitored and standardized under the guidance of a doctor.
