Acute thrombocytopenia can be treated with anti-infective, hormonal, and immunosuppressive drugs depending on the cause. There are many causes of acute thrombocytopenia, including infection and drugs, immune factors and hematologic diseases. 1. If it is caused by infection and medication, the infection should be controlled, and the medication includes levofloxacin, etc. If it is caused by medication, it is usually treated after stopping the medication. Drug-induced decrease can usually be recovered after stopping the medication. 2. If thrombocytopenia is caused by immune factors, it is necessary to treat the immune system diseases and give appropriate medication. For example, systemic lupus erythematosus should be treated with glucocorticoids such as prednisone. 3. If it is caused by idiopathic thrombocytopenia, hormones, eltrombopag, recombinant human thrombopoietin injection, rituximab and other drugs are given to control the disease. Therefore, for patients with acute thrombocytopenia, they should go to a general hospital for a detailed examination to clarify the specific cause of the disease and then give targeted treatment. The above drugs should be used under the guidance of a doctor.
