The drugs used to raise white blood cells after chemotherapy are divided into oral and subcutaneous injections. The oral ones are used for mild white blood cell reduction, and the commonly used drugs are Diyu Boost Tablets, Ricorun Tablets, Shark Liver Alcohol Tablets, Caffeic Acid Tablets, etc. Caffeic Acid Tablets can assist in raising white blood cells and platelets. There are short-acting granulocyte-stimulating factors injected subcutaneously, which are faster to raise and lower and last for a shorter period of time. Long-acting leukostimulating drugs include polyethylene glycolized recombinant human granulocyte stimulating factor, which is a long-acting leukostimulating drug that can be used to prevent leukocyte reduction in patients undergoing long-term chemotherapy and lasts for a longer period of time, and can continue to be effective for 1-14 days.
