What are the common side effects of pomalidomide and how to deal with them?

Pomalidomide (Pomalidomide), as an oral immunomodulatory drug, is an important option for the treatment of multiple myeloma, especially for patients who are resistant to lenalidomide and bortezomib. It is a thalidomide analogue with multiple mechanisms of action, such as enhancing the activity of T cells and natural killer cells, inhibiting the release of pro-inflammatory factors, and interfering with the tumor cell microenvironment. However, despite its clear efficacy, a variety of side effects may occur during the use of pomalidomide, which will have a certain impact on patients' quality of life. Therefore, reasonable identification and management of these adverse reactions is a key part of the treatment process.

In clinical practice, the most common side effects include myelosuppression, especially neutropenia and thrombocytopenia. Such side effects may make patients more susceptible to complications such as infection and bleeding. Treatment methods include adjusting the dose based on blood routine results, suspending medication if necessary, and supplementing with growth factors such as G-CSF or blood transfusion support. Secondly, fatigue is also a common discomfort symptom in patients taking pomalidomide, which can be improved by properly arranging rest, performing moderate exercise, and adjusting the medication time. Gastrointestinal reactions such as nausea, vomiting, diarrhea, etc. are also relatively common problems, which can usually be alleviated by using antiemetics, adjusting diet, or clinical symptomatic and supportive treatment.

Another side effect that cannot be ignored is the increased risk of venous thromboembolism, including deep vein thrombosis and even pulmonary embolism, especially when used in combination with glucocorticoids such as dexamethasone. Therefore, doctors often consider prophylaxis with drugs such as low-molecular-weight heparin or aspirin based on the patient's individual risk assessment. In addition, due to the teratogenicity of pomalidomide, patients must strictly avoid contraception during use, including the spouses of male patients, who also need to take effective contraceptive measures and continue to use contraception during the medication and for a certain period of time after stopping the medication.
