Advagraf 1mg Capsule, which contains the active ingredient tacrolimus, is used to prevent organ rejection in adults who have undergone a kidney or liver transplant. It works by suppressing the immune system, preventing it from attacking the newly transplanted organ. Advagraf can also be used to treat ongoing organ rejection when other immunosuppressants haven’t been effective. It’s important to take the medication as directed by a doctor and inform them about any pre-existing conditions or other medications.
