What are the side effects of pomalidomide capsules?

Pomalidomide (Pomalidomide) is an immunomodulatory drug. Its mechanism of action is derived from its profound impact on the immune microenvironment, including regulating T cells, inhibiting inflammatory signals in the tumor microenvironment, and interfering with angiogenesis. Therefore, while exerting anti-tumor effects, it will also cause certain side effects. Understanding these side effects can help patients better cope with the treatment process, improve drug tolerance, and achieve stability in the treatment cycle.

The most common adverse reactions of pomalidomide are mainly concentrated in the blood system, gastrointestinal tract, skin and nervous system. As an immunomodulator, it may cause some degree of cytopenias, such as a decrease in white blood cells, red blood cells, or platelets. When blood changes occur, patients may feel tired, susceptible to infection, or develop skin bruising, so regular blood tests are important. Doctors usually adjust the dose or take supportive care based on changes in blood levels.

In addition, gastrointestinal reactions are also problems that many patients are prone to encounter, including nausea, constipation, loss of appetite, etc. Some people will have digestive tract discomfort affecting their quality of life. Maintaining a reasonable diet, adequate fluids, and moderate activity can significantly help alleviate these reactions. For patients prone to constipation, doctors may recommend the use of mild laxatives in moderation.

Skin reactions, such as rash, itching, or localized erythema, are also a noteworthy side effect of pomalidomide. Most skin reactions are mild and related to immune regulatory mechanisms, but if extensive rash or severe discomfort occurs, medical treatment should be sought promptly. Some patients may also experience mild peripheral nerve symptoms, such as numbness or mild tingling, which usually improve gradually with dose adjustment.
