ABOUT ENVARSUS XR TREATMENT
Envarsus XR is a prescription medicine that contains tacrolimus, a type of medication called an immunosuppressant. It is an extended-release tablet used to prevent organ rejection after liver transplantation.
Its delivery system provides prolonged drug release and stable tacrolimus exposure with once-daily dosing. Other tacrolimus products include Prograf and Advagraf.
Envarsus XR is generally used as long-term or lifelong maintenance therapy after a liver transplant. Your transplant team will monitor your blood levels, kidney function, and liver function as part of your care.
WHO ENVARSUS XR MAY BE SUITABLE FOR
Envarsus XR is prescribed to people who have received a liver transplant and need long-term immunosuppressive therapy to prevent rejection. Your healthcare provider may choose it if a once-daily tacrolimus tablet would suit you, if they are working to optimize your tacrolimus exposure and tolerability, or if you are converting from another tacrolimus product.
Because every patient's health profile is different, there is no one-size-fits-all answer. Treatment decisions are individualized and should be made by your transplant healthcare team after a full assessment of your transplant status and treatment goals.
PRESCRIBING OVERVIEW
Your healthcare provider may consider Envarsus XR if any of the following apply:
Your transplant team checks several measures regularly to guide your treatment, including:
HOW ENVARSUS XR CAN HELP YOUR TRANSPLANTED LIVER
After a liver transplant, your immune system can mistake the new liver for a threat and attack it. This is called rejection. Envarsus XR lowers that risk.
Tacrolimus blocks an enzyme in immune cells called calcineurin. This reduces the activation of T-lymphocytes, the immune cells responsible for rejection.
Envarsus XR also releases tacrolimus gradually over 24 hours. This helps keep your drug exposure stable and supports long-term survival of the transplanted liver (the graft). Doses are commonly adjusted over time to maintain effective immunosuppression while minimizing side effects.
TRANSPLANT BENEFITS
Envarsus XR is used to prevent organ rejection after a liver transplant. By lowering the immune attack on your new liver, it helps protect the graft so it can keep doing its work. Your transplant team chooses and adjusts the medicine with this goal in mind.
The tablet releases tacrolimus gradually over 24 hours. This prolonged release helps maintain stable immunosuppressive drug exposure throughout the day. As part of regular monitoring, your team measures tacrolimus trough levels, which are blood levels of the medicine.
Envarsus XR supports transplant function and long-term graft survival. It is generally used as long-term or lifelong maintenance therapy after liver transplantation, unless your healthcare provider changes your treatment. Do not stop taking it without talking to your transplant team.
If you are converting from another tacrolimus product, Envarsus XR is one option your provider may consider. People who switch from immediate-release tacrolimus may need a lower total daily dose. Your provider may also choose it when working to optimize your tacrolimus exposure and tolerability.
Envarsus XR helps prevent rejection by calming the immune cells that can attack a transplanted liver. It should only be started, adjusted, and monitored by your transplant healthcare team.
TREATMENT PROCESS
Envarsus XR is supplied as an extended-release oral tablet. Take it exactly as prescribed by your healthcare provider.
Typical starting doses are 2-8 mg once daily. Your transplant team adjusts the dose regularly based on your tacrolimus blood levels, transplant status, and clinical response. If you are converting from immediate-release tacrolimus, you may need a lower total daily dose.
Take Envarsus XR once daily on an empty stomach, preferably at the same time each day. Swallow the tablet whole. Do not crush, split, or chew it.
