What are the side effects of afatinib combined with cabozantinib?

Both afatinib and cabozantinib may cause gastrointestinal upset. Common symptoms include diarrhea, nausea, and vomiting. Diarrhea usually occurs within the first few weeks of treatment, can be severe, and requires special attention. Patients should avoid foods or drinks that speed up bowel movements and may also take antidiarrheal treatment. At the same time, nausea and vomiting can also affect the patient's appetite and nutrient absorption, and pharmaceutical intervention may be needed to relieve symptoms.

Afatinib may cause skin problems such as rash, acne, dry skin, and itching. Cabozantinib may also cause skin reactions on the hands and feet, such as redness, pain, swelling, or blisters on the palms. Although these reactions are not usually life-threatening, they can seriously affect the patient's quality of life. Therefore, patients need to pay special attention to skin care, avoid scratching and excessive cleaning, and use moisturizers and anti-allergy medications when necessary.

In addition to the two major side effects mentioned above, afatinib and cabozantinib may cause a variety of other discomforts. For example, both can cause fatigue and feelings of weakness, affecting patients' daily activities. In addition, high blood pressure, oral ulcers, and abnormal liver function are also common side effects. When using these two drugs, patients should regularly monitor blood pressure and liver function to detect and deal with abnormalities in a timely manner.

Although less common, the combination of afatinib and cabozantinib can sometimes cause serious side effects, such as interstitial lung disease, liver failure, and severe bleeding. Therefore, patients should be cautious when using these two drugs and under the guidance of a doctor. If symptoms such as difficulty breathing, jaundice, or unexplained bleeding occur, seek medical attention immediately.
