What are the possible side effects of using lenvatinib/lenvatinib that you need to pay attention to?

Lenvatinib is a targeted drug that acts on a variety of angiogenesis and tumor signaling pathways, such as thyroid cancer. While improving tumor control rates, it also comes with a certain risk of side effects. Common side effects that patients experience while using this drug include hypertension, fatigue, loss of appetite, nausea, diarrhea, proteinuria, and hand-foot syndrome. Most of these reactions can be alleviated through dose adjustment or symptomatic treatment. However, if some reactions are not treated in time, they may have an impact on quality of life and treatment compliance.

Hypertension is one of the most important adverse reactions during lenvatinib treatment, and its mechanism may be related to vascular endothelial dysfunction caused by VEGF pathway inhibition. Patients need to monitor blood pressure regularly during the initial period of medication and throughout the treatment period. If a significant increase is found, antihypertensive treatment should be initiated promptly as directed by the doctor. Digestive tract discomfort, such as nausea, diarrhea, oral mucositis, etc., are also common problems reported by patients. If these symptoms affect food intake and nutritional intake, they may further weaken the body's resistance and require nutritional support and symptomatic treatment with drugs.

Hand-foot syndrome manifests as redness, swelling, peeling, or tingling on the skin of the hands and feet. In severe cases, it can interfere with daily activities. Patients are advised to use moisturizers and avoid wearing tight shoes or walking for long periods of time. In addition, lenvatinib may cause proteinuria or abnormal liver function indicators. Urinalysis and liver and kidney function monitoring should be performed regularly during medication. Rarely, thyroid dysfunction or adverse cardiac events may occur, so patients with a history of cardiovascular disease or thyroid disease should be particularly careful.

In short, the side effects of lenvatinib are predictable and manageable. The key lies in maintaining good communication between patients and doctors and establishing individualized monitoring and response plans. Once symptoms beyond the general reaction occur, you should seek medical treatment promptly and consider adjusting the dose or suspending treatment to ensure safety and continuity of treatment. Correctly understanding side effects and taking appropriate intervention are important steps in improving the success rate of treatment.
