There is no fastest way to recover platelets, and the cause of the disease needs to be clarified and treated. Commonly used methods include: platelet transfusion, taking platelet-raising drugs, and taking drugs that inhibit the production of platelet antibodies. 1. Platelet transfusion: this is a fast way to raise platelets, i.e., qualified platelets are imported into the patient’s body. However, there are strict indications and a reasonable platelet transfusion program should be formulated under the guidance of doctors. 2. Taking platelet-raising drugs: such as thrombopoietin, aminopterin, eltrombopagide, etc., which can increase the number of platelets in peripheral blood. 3. Drugs that inhibit the production of platelet antibodies: such as prednisone acetate and other glucocorticoids, which have an inhibitory effect on platelet antibodies and can prevent platelets from binding with antibodies. It is worth noting that all the above dispositions or medications need to be carried out after the doctor has identified the cause, to avoid blind use of drugs.
