The treatment taken for low platelets caused by taking targeted drugs includes rest, stopping the drug, platelet transfusion, prevention of bleeding, cytokines and thrombopoietin. 1. Absolute rest. 2. Discontinuation or reduction of medication: targeted drugs such as Vinaclat can cause bone marrow suppression, resulting in a decrease in platelet count and function. 3. Platelet transfusion: Rapidly elevate the platelet count to prevent bleeding from occurring. If the patient has third-degree thrombocytopenia and has a bleeding tendency, a single platelet transfusion should be given. If the patient has 4th degree thrombocytopenia, it should be used regardless of bleeding tendency. 4. Prevention of bleeding: e.g., aminocaproic acid sodium chloride, aminocaproic acid, etc. 5. Cytokines (IL-11) and thrombopoietin (TPO): cytokines and thrombopoietin can significantly shorten the duration of thrombocytopenia, and may be considered if platelets are less than (40~60)×10⁹/L and are likely to continue to decline. Platelets should be transfused in addition to IL-11 and TPO when platelets are less than (20 to 40) × 10⁹/L and there is a tendency to bleed. Taking targeted drugs caused by low platelets, it is recommended to go to the hospital in time to improve the examination, under the guidance of physicians to give targeted treatment or treatment.
