Treatment and precautions when taking Eltrombopag (Revlan) is ineffective

Eltrombopag is an oral thrombopoietin receptor agonist used to treat chronic immune thrombocytopenia (ITP), aplastic anemia and certain liver disease-related thrombocytopenia. When a patient takes eltrombopag at the standard dose but does not experience an expected increase in platelets, medication compliance, medication administration methods and potential influencing factors should first be assessed. The absorption of eltrombopag is affected by food and minerals such as calcium, iron, and magnesium. If taken with high-calcium or iron foods, the efficacy of the drug may be reduced. Therefore, patients must strictly follow the doctor's instructions on an empty stomach or take it with water to ensure drug absorption.

If the medication is still ineffective after ruling out medication method and compliance problems, the doctor will usually evaluate the possibility of dosage adjustment. Clinically, the starting dose of eltrombopag is 25–50 mg/ days, which can be gradually adjusted according to platelet response, but any dose adjustment must be made under the guidance of a doctor. Increasing the dose without your doctor's permission may cause excessive elevation of platelets and increase the risk of blood clots. Regular blood routine monitoring is required when adjusting the dose to ensure that platelet levels are within a safe range and to avoid drug side effects.

When dealing with invalid situations, possible secondary factors need to be investigated. In some patients, the efficacy of eltrombopag may be reduced due to underlying disease activity, infection, drug interactions, or changes in autoimmune status. For example, platelet production may be affected in patients who are taking immunosuppressants or have abnormal liver function. At this time, doctors should work together to adjust the comprehensive treatment plan, such as optimizing immunotherapy, correcting nutritional and liver function abnormalities, to improve platelet response.

Finally, patients need to pay special attention to safety and frequency of monitoring during the period when eltrombopag is ineffective. It is very important to regularly test platelets, liver function and other hematological indicators, and pay attention to the occurrence of symptoms of bleeding, ecchymosis or thrombosis. In the event of any abnormality, seek medical attention immediately. Through dose optimization, lifestyle adjustment and combined treatment under the guidance of doctors, most patients can still achieve platelet improvement and achieve safe and effective treatment.
