What should I do if there is no effect after taking Cabozantinib for more than ten days?

Taking cabozantinib for more than ten days has no effect. First of all, it needs to be clear that the effect of drug treatment varies from person to person, and the response time of different diseases to the drug will also be different.

Considering that cabozantinib usually requires continued use to show its effects, more than ten days may not be enough to judge whether the drug is truly effective. Therefore, it is recommended to continue observation for a period of time under the guidance of a doctor.

If after a period of observation, no obvious effect is still seen, then you need to work with your doctor to evaluate whether drug resistance has developed. Drug resistance may occur due to weakened response of tumor cells to drugs or genetic mutations.

Confirm whether the patient is taking medication in strict accordance with the doctor's instructions, including medication time, dosage, etc. Any deviation may affect the effectiveness of the drug.

If there are no problems with the medication method and dosage, but the effect is still not good, the doctor may consider adjusting the drug dosage or changing the medication method to find the best therapeutic effect.

If cabozantinib alone is not effective, your doctor may consider combining it with other drugs or treatments to enhance its effectiveness. After confirming that cabozantinib is ineffective for the patient, doctors may consider switching to other targeted drugs or treatment options. For example, according to some clinical data, capmatinib (280) may be an effective alternative for patients who are resistant to EGFR targeted drugs and have positive MET amplification.

While adjusting the treatment plan, it is also necessary to pay close attention to whether the patient has drug side effects, such as diarrhea, fatigue, loss of appetite, etc., and deal with them in a timely manner to alleviate the patient's discomfort. During treatment, it is also important to focus on the patient's quality of life. Doctors can advise patients on appropriate exercise and dietary adjustments to improve physical fitness and enhance immunity.
