ABOUT PROGRAF TREATMENT
Prograf is a prescription medicine that contains tacrolimus. It is an immunosuppressant used to prevent organ rejection after liver transplantation. Prograf belongs to a class of medications called calcineurin inhibitors, and it is commonly used as a cornerstone of long-term maintenance immunosuppressive therapy.
Prograf is an immediate-release form of tacrolimus, available as capsules and oral suspension. Extended-release forms of tacrolimus are covered on the Advagraf and Envarsus XR pages.
Prograf is used as part of an individualized post-transplant regimen. It comes with regular monitoring by your transplant team, including blood tests such as Liver Function Tests (LFTs).
WHO PROGRAF MAY BE PRESCRIBED FOR
Your healthcare provider may prescribe Prograf if you have received a liver transplant and need long-term prevention of organ rejection. It may also be used when you need maintenance immunosuppressive therapy, when your provider is establishing an individualized post-transplant regimen, or when you need an immediate-release tacrolimus formulation.
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. Your team chooses the medication, dose, and schedule that fit your transplant status and response, and may change your regimen over time.
ELIGIBILITY OVERVIEW
Prograf may be considered for adults with the following situations or treatment goals:
Your transplant healthcare team sets up your regimen and adjusts it over time, including:
HOW PROGRAF PROTECTS YOUR NEW LIVER
After a transplant, your immune system can recognize the new liver as foreign and attack it. This is called rejection. Prograf lowers that risk by blocking an enzyme called calcineurin inside immune cells.
When calcineurin is blocked, T-lymphocytes (a type of immune cell involved in organ rejection) become less active. This suppresses the immune response against the transplanted liver and helps it keep working over the long term. It reduces the risk of both acute and chronic rejection.
Prograf is not used on its own. Your transplant team pairs it with regular blood tests, follow-up visits, and healthy daily habits to protect your liver.
TRANSPLANT BENEFITS
Prograf inhibits calcineurin activity in immune cells. This reduces the activation of T-lymphocytes, the immune cells involved in organ rejection. With less T-lymphocyte activity, your immune system is less likely to attack the new liver.
By suppressing immune responses against the transplanted liver, Prograf reduces the risk of both acute and chronic rejection. Preventing rejection is the main purpose of long-term maintenance immunosuppressive therapy, and Prograf is a cornerstone of that therapy.
Prograf helps maintain long-term graft function. The graft is the transplanted liver. Because Prograf is generally taken as long-term or lifelong maintenance therapy, it keeps protecting your liver well beyond the early period after transplant.
Doses are often higher right after transplant and gradually reduced to the lowest effective maintenance dose. Your team adjusts the dose based on your tacrolimus blood levels, transplant status, and clinical response, so treatment can change as your needs change.
Prograf helps prevent your immune system from rejecting your transplanted liver. It should only be started and monitored under the guidance of your transplant healthcare team.
TREATMENT PROCESS
Prograf is available as immediate-release capsules and an oral suspension. Take it exactly as prescribed by your healthcare provider.
Typical starting doses are 1-4 mg twice daily. Your healthcare provider adjusts the dose regularly based on your tacrolimus blood levels, transplant status, and clinical response. Doses are often higher right after transplant and gradually reduced to the lowest effective maintenance dose.
Take Prograf by mouth every 12 hours, at the same times each day. Take it consistently either with or without food, as your healthcare provider instructs, to keep your drug levels stable.
Prograf is generally taken as long-term or lifelong maintenance therapy after liver transplantation. Do not stop or change it unless your healthcare provider changes your immunosuppressive regimen.
Store Prograf at room temperature, away from moisture and heat.
Regular monitoring of tacrolimus trough levels, kidney function, liver function, blood pressure, and blood glucose is required. Attend all scheduled laboratory tests and transplant follow-up visits, and report any side effects or unusual symptoms to your healthcare provider.
BENEFITS AND SAFETY
Prograf (tacrolimus) helps protect your transplanted liver by lowering the risk of rejection. It is a widely used, established transplant medication, and its dose can be adjusted to fit your needs. The extent of benefit varies from person to person, depending on your transplant status and how your body responds. Prograf works best as part of a broader care plan that includes regular blood tests, follow-up visits, and healthy daily habits.
As with any medication, Prograf may cause side effects. Your transplant team will monitor your blood levels, kidney function, blood pressure, and blood sugar throughout treatment and adjust your care plan as needed to balance benefits and risks.
BENEFITS
Prograf is a widely used, standard transplant medication. As the immediate-release form of tacrolimus, it is one of several tacrolimus options your transplant team can choose from, along with the extended-release forms Advagraf and Envarsus XR. Your team selects the option that fits your individualized regimen.
Prograf comes as immediate-release capsules and as an oral suspension. Your healthcare provider will tell you which form to use and how to take it. If you have questions about the form you receive, ask your transplant team before making any change.
Regular tacrolimus trough level checks give your team a clear way to follow how you are doing. Your team also checks your kidney function, liver function, blood pressure, and blood glucose. Together, these results help your team balance the benefits and risks of Prograf and adjust your care plan as needed.
Prograf follows a simple twice-daily pattern, with one dose about every 12 hours. Because the schedule stays the same from day to day, it is easy to tie to set times in your morning and evening. Keeping those times, and keeping to the same routine with or without food as your healthcare provider instructs, helps keep your drug levels stable. If the schedule is hard to keep, tell your transplant team.
Your transplant healthcare team will discuss the potential benefits and risks before treatment and monitor you with regular blood tests, including kidney function, blood pressure, and blood glucose. Report any side effects or unusual symptoms to your healthcare provider.
SUPPORTING YOUR RESULTS
Daily habits are an important part of life after transplant alongside Prograf. Taking your medication on schedule, avoiding grapefruit, and protecting yourself from infection and sun exposure all help protect your new liver.
These habits can support how your body responds to treatment and help keep your transplanted liver healthy over time.
