Clinically, if a patient has a lower than normal number of white blood cells in the peripheral blood, it is called leukopenia. Patients with leukopenia often need to raise their white blood cell count. There are two types of medications that are used clinically to raise the white blood cell count: the first is oral medications. The first category is oral medications, which include diethylstilbestrol tablets, vitamin B4, shark’s liver alcohol, licoquinone, diethylstilbestrol capsules, etc. These oral leukocyte-raising medications usually require a combination of two or three types for better results. The second category is injections. This is a cytokine that can bind to the receptors of granulocytes, promote the proliferation and division of granulocytes, and release them into the peripheral blood, and also increase the phagocytosis of neutrophils, which is often used clinically in malignant tumor patients with severely reduced white blood cell count after chemotherapy.
