Why is this medication prescribed?
Tacrolimus Injection is prescribed for its immunosuppressive properties and is primarily used in the following medical situations:
- Organ Transplantation: Tacrolimus is commonly prescribed to transplant recipients to prevent the rejection of transplanted organs, such as the kidney, liver, heart, or lung. It works by suppressing the immune system, which helps prevent the body from attacking and rejecting the newly transplanted organ.
- Graft-versus-Host Disease (GVHD): Tacrolimus may also be used in the treatment of graft-versus-host disease, a condition that can occur after a stem cell or bone marrow transplant. GVHD happens when the transplanted cells attack the recipient’s tissues, and tacrolimus helps suppress this immune response.
How should this medicine be used?
The dosage and administration of Tacrolimus Injection are specific to each patient and depend on factors such as the type of organ transplant, the patient’s medical condition, and individual response to the medication. It is crucial to follow the healthcare provider’s instructions carefully. Here are general guidelines for the use of Tacrolimus Injection:
