How long does it take to stop taking erlotinib?

Erlotinib (Erlotinib) use and withdrawal times vary depending on the patient's specific condition. Typically, erlotinib is a long-term treatment that needs to be continued for a period of time to control tumor growth and spread. After patients start taking erlotinib, doctors will conduct regular monitoring and evaluation based on tumor response and changes in condition. Stopping the use of erlotinib needs to be based on your doctor's advice and judgment of your condition. If the tumor is effectively controlled and the patient's condition is stable, doctors may consider reducing the dose or suspending the drug to avoid side effects and improve quality of life. However, discontinuation of the drug may lead to tumor reactivation, so the decision to discontinue the drug needs to be very cautious and must be made under the guidance of a physician.
