What is a good tacrolimus level for liver transplant patients?
Background: Tacrolimus is an important immunosuppressant administered to patients following liver transplantation (LT), with a recommended trough concentration of 8 to 11 ng/mL to prevent allograft rejection.
What is a good range for tacrolimus?
Most individuals display optimal response to tacrolimus with trough whole blood levels of 5.0 to 15.0 ng/mL. Preferred therapeutic ranges may vary by transplant type, protocol, and comedications.
What is a normal tacrolimus level for a kidney transplant patient?
Tacrolimus is also monitored by trough levels, and again, each patient will have their own target levels. As a guide (for patients who are >12 months post transplant), we aim for levels between 5 – 8 ng / ml.
What is considered high tacrolimus level?
Tacrolimus trough levels higher than 6 ng/mL might not be required after a year in stable kidney transplant recipients.
How often should tacrolimus levels be checked?
Blood samples for trough levels are taken between 08:00 hrs and 10:00 hrs, six days a week. Trough levels, liver and renal function tests are available for the evening ward round when the drug dosage is adjusted, according to need on a per patient basis, in order to achieve the appropriate blood tacrolimus levels.
What do tacrolimus levels tell you?
The tacrolimus test is used to measure the amount of drug in the blood to determine whether the concentration has reached a therapeutic level and is below the toxic level.
What happens if your tacrolimus is too high?
Using too much will increase the chance for side effects, while using too little may cause rejection of your transplanted organ. This medicine comes with a Medication Guide or a patient information insert and patient instructions.
What causes tacrolimus levels to be low?
*Conclusions: Low tacrolimus trough levels (<3.5 ng / ml), are related to changes of brands and greater variability of the trough levels. These trough levels are related to acute rejection and short-term creatinine duplication.
What causes tacrolimus levels to drop?
What are the symptoms of high tacrolimus levels?
Tacrolimus may cause your blood pressure to increase….Also call your doctor at once if you have:
- general ill feeling, pain or swelling near your transplanted organ;
- headaches, vision changes, pounding in your neck or ears;
- confusion, behavior changes;
- a seizure;
What are symptoms of low tacrolimus levels?
low levels of magnesium or phosphate; numbness or tingling in your hands and feet; sleep problems (insomnia); or. swelling in your hands, legs, ankles, or feet.
How long does tacrolimus stay in your system?
The terminal elimination half-life (t1/2beta) of tacrolimus is approximately 12 hours (with a range of 3.5 to 40.5 hours). Only limited information is available on the pharmacokinetics of tacrolimus in paediatric patients.
What should the tacrolimus level be after a kidney transplant?
Modeling was used to establish the correlation between the doses administered per kilogram of body weight, the tacrolimus level measured and the post-transplantation time. Of 155 tacrolimus measurements, only 48.4% were found within the therapeutic range (5-10 ng/mL); 7.1% below and 44.5% with elevated levels.
What should my Tac level be on sirolimus?
Since I was on tacrolimus only (as Mycophenolate causes TLC to go down in two occasion), sirolimus 1mg is started along with reduced tacrolimus (2mg BD, Tac level ~4.5). But the creatinine is still high (1.8).
What should whole blood trough concentration be for tacrolimus?
-Whole blood trough concentrations usually range from 5 to 20 ng/mL. Extra caution and closer monitoring are recommended when graft function changes or drug interactions are suspected. -Monitoring of cyclosporine blood concentrations should be continued post-conversion as tacrolimus may affect the clearance of cyclosporine.
What are the side effects of a high tacrolimus level?
Side effects such as tremors, headache, high blood pressure, nausea and vomiting, electrolyte disturbances, and tinnitus may be seen at any dosage but tend to be more severe with a higher tacrolimus level. It is best that you discuss the results with your attending physician for proper evaluation.
