1. What Envarsus is and what it is used for

Envarsus contains the active substance tacrolimus. It is an immunosuppressant. Following your kidney or liver transplant, your body’s immune system will try to reject the new organ.

Envarsus is used to control your body’s immune response, enabling your body to accept the transplanted organ.

You may also be given Envarsus for an ongoing rejection of your transplanted liver, kidney, heart or other organ when any previous treatment you were taking was unable to control this immune response after your transplantation.

Envarsus is used in adults.

2. What you need to know before you take Envarsus
Do not take Envarsus
  • if you are allergic to tacrolimus or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to sirolimus or to any macrolide-antibiotic (e.g., erythromycin, clarithromycin, josamycin).

Warnings and precautions

Envarsus contains the active substance tacrolimus presented in a prolonged release formulation. Envarsus is taken once daily and is not interchangeable with other existing medicines containing tacrolimus (immediate release or prolonged release) on an equal dose by dose basis.

Talk to your doctor or pharmacist before taking Envarsus:

  • if you have, or have had, liver problems.
  • if you have diarrhoea for more than one day.
  • if you are taking any medicines mentioned below under “Other medicines and Envarsus”.
  • if you have an alteration of the electrical activity of your heart called “QT prolongation”.
  • if you feel strong abdominal pain accompanied or not with other symptoms, such as chills, fever, nausea or vomiting
  • an infection, leading to problems with your kidney or neurological symptoms
  • headache, altered mental status, seizures and visual disturbances
  • weakness, change in skin or eye colour, easy bruising, infection, cough, anaemia
  • if you have or have had damage to the smallest blood vessels, known as thrombotic microangiopathy/ thrombotic thrombocytopenic purpura/haemolytic uraemic syndrome. Tell your doctor if you develop fever, bruising under the skin (which may appear as red dots), unexplained tiredness, confusion, yellowing of the skin or eyes, reduced urine output, vision loss and seizures (see section 4).
    When tacrolimus is taken together with sirolimus or everolimus, the risk of developing these symptoms may increase.

Please avoid taking any herbal remedies, e.g., St. John’s wort (Hypericum perforatum) or any other herbal products as this may affect the effectiveness and the dose of Envarsus that you need to receive. If in doubt, please consult your doctor prior to taking any herbal products or remedies.

Your doctor may need to adjust your dose of Envarsus or will decide to stop treatment with tacrolimus.

You should keep in regular contact with your doctor.

From time to time, your doctor may need to do blood, urine, heart, or eye tests, to set the right dose of Envarsus.

You should limit your exposure to the sun and UV (ultraviolet) light whilst taking Envarsus. This is because immunosuppressants could increase the risk of skin cancer. Wear appropriate protective clothing and use a sunscreen with a high sun protection factor.

Children and adolescents

The use of Envarsus is not recommended in children and adolescents under 18 years.

Other medicines and Envarsus

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including medicines obtained without a prescription and herbal preparations.

It is not recommended that Envarsus is taken with ciclosporin (another medicine used for the prevention of transplant organ rejection).

If you need to attend a doctor other than your transplant specialist, tell the doctor that you are taking tacrolimus. Your doctor may need to consult your transplant specialist if you should use another medicine that could increase or decrease your tacrolimus blood level.

Envarsus blood levels can be affected by other medicines you take, and blood levels of other medicines can be affected by taking Envarsus, which may require interruption, an increase or a decrease in Envarsus dose.

Some patients have experienced increases in tacrolimus blood levels while taking other medicines.

This could lead to serious side effects, such as kidney problems, nervous system problems, and heart rhythm disturbances (see section 4).

An effect on the Envarsus blood levels may occur very soon after starting the use of another medicine, therefore frequent continued monitoring of your Envarsus blood level may be needed within the first few days of starting another medicine and frequently while treatment with the other medicine continues. Some other medicines may cause tacrolimus blood levels to decrease, which could increase the risk of rejecting the transplanted organ. In particular, you should tell your doctor if you are taking or have recently taken medicines like:

  • antifungal medicines and antibiotics, particularly so-called macrolide antibiotics, used to treat infections (e.g., ketoconazole, fluconazole, itraconazole, posaconazole, voriconazole, clotrimazole, isavuconazole, miconazole, caspofungin, telithromycin, erythromycin, clarithromycin, josamycin, azithromycin, rifampicin, rifabutin, isoniazid and flucloxacillin)
  • letermovir, used to prevent illness caused by CMV (human cytomegalovirus)
  • HIV protease inhibitors (e.g., ritonavir, nelfinavir, saquinavir), the booster medicine cobicistat and combination tablets, or HIV non-nucleoside reverse transcriptase inhibitors (efavirenz, etravirine, nevirapine) used to treat HIV infection
  • HCV protease inhibitors (e.g., telaprevir, boceprevir, the combination ombitasvir/paritaprevir/ritonavir with or without dasabuvir, elbasvir/grazoprevir, and glecaprevir/pibrentasvir), used to treat hepatitis C
  • nilotinib and imatinib, idelalisib, ceritinib, crizotinib, apalutamide, enzalutamide or mitotane (used to treat certain cancers)
  • mycophenolic acid, used to suppress the immune system to prevent transplant rejection
  • medicines for stomach ulcer and acid reflux (e.g., omeprazole, lansoprazole or cimetidine)
  • antiemetics, used to treat nausea and vomiting (e.g., metoclopramide)
  • cisapride or the antacid magnesium-aluminium-hydroxide, used to treat heartburn
  • the contraceptive pill or other hormone treatments with ethinylestradiol, hormone treatments with danazol
  • medicines used to treat high blood pressure or heart problems (e.g., nifedipine, nicardipine, diltiazem and verapamil)
  • anti-arrhythmic substances (e.g., amiodarone) used to control arrhythmia (uneven beating of the heart)
  • medicines known as “statins”, used to treat elevated cholesterol and triglycerides
  • carbamazepine, phenytoin or phenobarbital, used to treat epilepsy
  • metamizole, used to treat pain and fever
  • the corticosteroids prednisolone and methylprednisolone, belonging to the class of corticosteroids and used to treat inflammations or suppress the immune system (e.g., in transplant rejection)
  • nefazodone, used to treat depression
  • herbal preparations containing St. John’s Wort (Hypericum perforatum) or extracts of Schisandra sphenanthera
  • cannabidiol (uses amongst others include treatment of seizures)

Tell your doctor if you are receiving treatment for hepatitis C. The drug treatment for hepatitis C may change your liver function and may affect blood levels of tacrolimus. Tacrolimus blood levels may fall or may increase depending on the medicines prescribed for hepatitis C. Your doctor may need to closely monitor tacrolimus blood levels and make adjustments to the dose after you start treatment for hepatitis C.

Tell your doctor if you are taking or need to take ibuprofen (used to treat fever, inflammation and pain), antibiotics (cotrimoxazole, vancomycin, or aminoglycoside antibiotics such as gentamicin), amphotericin B (used to treat fungal infections) or antivirals (used to treat viral infections, e.g. acyclovir, ganciclovir, cidofovir, foscarnet). These may worsen kidney or nervous system problems when taken together with Envarsus.

Tell your doctor if you are taking sirolimus or everolimus. When tacrolimus is taken together with sirolimus or everolimus, the risk of developing thrombotic microangiopathy, thrombotic thrombocytopenic purpura, and haemolytic uraemic syndrome may increase (see section 4).

While you take Envarsus your doctor also needs to know if you are taking potassium supplements or certain diuretics used for heart failure, hypertension and kidney disease (e.g., amiloride, triamterene, or spironolactone), or the antibiotics trimethoprim or cotrimoxazole that may increase levels of potassium in your blood, nonsteroidal anti-inflammatory substances (NSAIDs, e.g., ibuprofen) used for fever, inflammation and pain, anticoagulants (blood thinners), or oral medicines for diabetes.

If you need to have any vaccinations, please tell your doctor before.

Envarsus with food and drink

Avoid grapefruit (also as juice) while on treatment with Envarsus, since it can affect its levels in the blood.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Tacrolimus passes into breast milk. Therefore, you should not breast-feed whilst taking Envarsus.

Driving and using machines

Do not drive or use any tools or machines if you feel dizzy or sleepy, or have problems seeing clearly after taking Envarsus. These effects are more frequent if you also drink alcohol.

Envarsus contains lactose

Envarsus contains lactose (milk sugar).

  • Envarsus 0.75 mg tablets: 41.7 mg
  • Envarsus 1 mg tablets: 41.7 mg
  • Envarsus 4 mg tablets: 104 mg

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

3. How to take Envarsus

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

This medicine should only be prescribed for you by a doctor with experience in the treatment of transplant patients.

Important information

Make sure that you receive the same tacrolimus medicine every time you collect your prescription, unless your transplant specialist has agreed to change to a different tacrolimus medicine.

This medicine should be taken once a day. If the appearance of this medicine is not the same as usual, or if dose instructions have changed, speak to your doctor or pharmacist as soon as possible to make sure that you have the right medicine.

How much Envarsus do I have to take

The starting dose to prevent the rejection of your transplanted organ will be determined by your doctor calculated according to your body weight.

Initial daily doses just after transplantation will generally be in the range of:

0.11 - 0.17 mg per kg body weight per day depending on the transplanted organ. When treating rejection, the same doses may be used.

Your dose depends on your general condition and on which other immunosuppressive medicines you are taking. Following the initiation of your treatment with this medicine, frequent blood tests will be taken by your doctor to define the correct dose. Afterwards regular blood tests by your doctor will be required to define the correct dose and to adjust the dose from time to time.

Your doctor will usually reduce your Envarsus dose once your condition has stabilised.

How should I take the Envarsus tablets

Envarsus is taken orally once daily, generally on an empty stomach.

Take the tablets immediately following removal from the blister. The tablets should be swallowed whole with a glass of water. Do not swallow the desiccant contained in the foil wrapper.

How long should I take the Envarsus tablets

You will need to take Envarsus every day as long as you need immunosuppression to prevent rejection of your transplanted organ. You should keep in regular contact with your doctor.

If you take more Envarsus than you should

If you have accidentally taken too much Envarsus, contact your doctor or nearest hospital emergency department immediately.

If you forget to take Envarsus

Do not take a double dose to make up for a forgotten tablet. Take the tablet as soon as possible on the same day.

If you stop taking Envarsus

Stopping your treatment with Envarsus may increase the risk of rejection of your transplanted organ. Do not stop your treatment unless your doctor tells you to do so.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Tacrolimus reduces your body’s defence mechanism (immune system), which will not be as good at fighting infections. Therefore, you may be more prone to infections while you are taking Envarsus. Some infections could be serious or fatal and may include infections caused by bacteria, viruses, fungi, parasites, or other infections.

Tell your doctor immediately if you get signs of an infection including:

  • fever, cough, sore throat, feeling weak or generally unwell
  • memory loss, trouble thinking, difficulty walking or loss of vision - these may be due to a very rare, serious brain infection, which can be fatal (Progressive Multifocal Leukoencephalopathy (PML))
