What are the side effects of Zolbetuximab (Vyloy, Zolbetuximab) and how to deal with them?

Zolbetuximab (Vyloy, Zolbetuximab), as an innovative gastric cancer treatment drug, has demonstrated significant therapeutic effects by targeting the Claudin 18.2 protein on the surface of gastric cancer cells. However, like most targeted drugs, zotuximab may be associated with certain side effects during treatment. Understanding these side effects and how to manage them is critical for patients and their families.

The most common adverse effects of zotuximab treatment include nausea, vomiting, decreased appetite, neutropenia, and weight loss. These side effects affect the patient's quality of life to a certain extent, but with reasonable medical intervention, most symptoms can be effectively controlled. For nausea and vomiting, doctors often prescribe antiemetic drugs to help patients relieve symptoms. In addition, adjusting the drug infusion rate or temporarily interrupting treatment are also common strategies to reduce the occurrence of adverse reactions. For loss of appetite and weight, it is recommended that patients eat small and frequent meals and choose highly nutritious and easy-to-digest foods to maintain physical strength.

In addition to the common side effects mentioned above, patients may also experience other adverse reactions, such as allergic reactions, skin reactions (such as rash), hematological toxicity, etc. Anaphylaxis usually occurs within a short period of time after the first infusion, manifesting as fever, chills, rash and other symptoms, and can be life-threatening in severe cases. Therefore, before using zotuximab, doctors will ask the patient in detail about the patient's allergic history and take preventive measures, such as pre-administration of antihistamines and glucocorticoids. For skin reactions, patients with mild symptoms can be relieved with topical drugs or oral anti-allergic drugs, while patients with severe symptoms need to seek medical treatment in time.

In summary, zotuximab may be associated with certain side effects while treating gastric cancer. However, through reasonable medical intervention and the patient's active cooperation, most symptoms can be effectively controlled. Patients should pay close attention to their own conditions during medication and inform their doctors in time if they experience any discomfort. At present, the drug is only sold overseas, with a box costing about more than 10,000 yuan.
