Seven major side effects of sunitinib: common adverse reactions and preventive measures

As a targeted therapy drug, Sunitinib has achieved remarkable results in the treatment of advanced renal cell carcinoma (RCC), gastrointestinal stromal tumors (GIST) and other tumors, but it is also accompanied by certain side effects. Understanding the common adverse reactions and preventive measures of sunitinib is crucial for patients and medical staff to manage the treatment process and improve treatment effects.

First, fatigue is one of the most common side effects of sunitinib treatment. Patients may feel exhausted and in a poor mental state. Fatigue usually develops within a few weeks of starting treatment and may continue until treatment ends. In order to relieve fatigue, patients should maintain appropriate rest, avoid overexertion, arrange daily activities reasonably, and reduce discomfort by adjusting drug dosage if necessary.

Secondly, hypertension is also a common adverse reaction of sunitinib. This drug may increase blood pressure by affecting vascular endothelial growth factor (VEGF). Patients should monitor their blood pressure regularly, maintain a healthy diet, reduce salt intake, and use antihypertensive drugs for intervention according to doctor's recommendations. If hypertension is severe, sunitinib may need to be withheld until blood pressure returns to normal.

Third, gastrointestinal discomfort, such as nausea, vomiting, and diarrhea, are also common side effects of sunitinib. To reduce these symptoms, patients can take medications after meals rather than on an empty stomach. In addition, patients can reduce nausea by taking anti-nausea drugs. If diarrhea symptoms persist, they need to consult a doctor in time to adjust the drugs or use symptomatic drugs.

Fourth, hand-foot syndrome is a common skin reaction to sunitinib. Patients may experience redness, swelling, pain, or peeling on their hands and feet. To prevent or relieve this symptom, patients can use moisturizer, keep the skin on their hands and feet dry, and avoid excessive friction. If necessary, your doctor can adjust the medication dose based on the severity of your symptoms.

Fifth, oral ulcers also occur in some patients, manifesting as painful ulcers in the mouth. To prevent oral ulcers, patients can use oral care products such as mouthwash to keep their mouths clean and avoid spicy and irritating foods.

Sixth, liver function impairment is a serious side effect of sunitinib. Abnormal liver function may lead to symptoms such as jaundice and loss of appetite, so liver function needs to be checked regularly during treatment. Once abnormal liver function is detected, medication may need to be suspended and appropriate intervention performed.

Finally, leukopenia is a risk factor during sunitinib treatment and may lead to decreased immune system function and increased risk of infection. Patients should have regular blood tests and seek medical attention promptly when signs of infection appear.

In short, although sunitinib is an effective targeted drug, it is also associated with many side effects. Patients should maintain close communication with their doctors during treatment, conduct regular examinations, adjust treatment plans in a timely manner, and take corresponding preventive and symptomatic measures to improve the safety and effectiveness of treatment.
