There is no specific dosage reduction program for Tacrolimus Capsules, it needs to be based on the patient’s condition, and should not be blindly reduced or discontinued. Tacrolimus capsule is a potent immunosuppressant. It can prevent graft rejection after liver or kidney transplantation and treat graft rejection after liver or kidney transplantation that cannot be controlled by other immunosuppressive drugs. Therefore, dosage reduction should be based on the severity of the patient’s rejection after liver or kidney transplantation. If the dosage is reduced blindly, the drug may not be able to effectively inhibit the body’s rejection reaction, causing the body’s immune system to be attacked and damaged after transplantation. It is recommended that the drug should be used under the guidance of a doctor, and should not be reduced or discontinued on its own.
