Taking bicalutamide for 6 years is usually not discontinued. Clinically bical bicalutamide belongs to non-steroidal anti-androgen drugs, but has no other endocrine effects, and is able to bind to the androgen receptor without activating the expression of its genes, thus inhibiting the stimulation of androgens and leading to the shrinkage of prostate tumors. It is mainly used to treat locally advanced prostate cancer without distant metastases. Usually the drug needs to be taken regularly for a long period of time in accordance with the doctor’s instructions. Suddenly stopping the drug after taking it for 6 years may lead to recurrence or even aggravation of the disease, which is not conducive to the health of the body. If necessary, you can follow the doctor’s advice to gradually reduce the dosage, or replace other drugs of the same type for treatment. In the process of taking the drug, it should be noted that it may cause dizziness, drowsiness, dyspnea, sweating and other uncomfortable symptoms, so it is not recommended to operate machinery or drive a vehicle after taking the drug, and it is forbidden for people who are allergic to the components of the drug. If it is necessary to stop taking bicalutamide due to medical conditions, it is recommended to consult a doctor in time, and after a comprehensive assessment of the condition of the doctor to decide how to stop taking the drug and the precautions to be taken.
