Description
Tacrolimus belongs to a group of medicines
Libitol known as immunosuppressive agents. It is used to lower the body's natural immunity in patients who receive organ (for example, kidney, liver, pancreas, lung, and heart) transplants.
When a patient receives an organ transplant, the body's white blood cells will try to get rid of (reject) the transplanted organ. Tacrolimus works by preventing the white blood cells from getting rid of the transplanted organ.
Tacrolimus may also be used for other indications, as determined by your doctor.
Tacrolimus is a very strong medicine. It can cause side effects that can be very serious, such as kidney problems. It may also reduce the body's ability to fight infections. You and your doctor should talk about the good this medicine will do as well as the risks of using it.
Tacrolimus is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although not specifically included in the product labeling, tacrolimus is used in certain patients with the following medical conditions:
- Bone marrow transplantation
- Uveitis, severe, refractory (an eye condition)
For patients receiving bone marrow transplantation, tacrolimus may work by preventing the cells from the transplanted bone marrow from attacking the cells of the patient. The dose of tacrolimus for patients receiving bone marrow transplantation is based on body weight. The usual dose is 0.12 to 0.3 mg per kg (0.05 to 0.14 mg per pound) of body weight a day for patients taking tacrolimus by mouth, and 0.04 to 0.1 mg per kg (0.018 to 0.045 mg per pound) of body weight a day for patients receiving tacrolimus by injection.
The dose of tacrolimus for patients with severe, refractory uveitis is based on body weight. For severe, refractory uveitis, the usual dose is 0.1 to 0.15 mg per kg (0.045 to 0.068 mg per pound) of body weight a day.
