Tacni – Tacrolimus uses, dose and side effects


0.5, 1, and 5 mg capsule, hard
tacrolimus respectively

What Tacni is and what it is used for

Tacna belongs to a group of medicines called immunosuppressants. After your organ transplant (e.g. liver, kidney, heart), your body’s immune system tries to reject the new organ. Tacni is used to control your body’s immune system to accept the transplanted organ. Tacni is often used in combination with other drugs that also suppress the immune system.

You may also be given Tacni against an ongoing rejection reaction of your transplanted liver, kidney, heart, or another organ, or if other previous treatments you received failed to control the immune system after your transplant.

The tacrolimus contained in Tacni may also be approved to treat other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you take Tacni

Do not take Tacni

  • if you are allergic to tacrolimus or any other ingredient in this medicine. (listed in section 6).
  • if you are allergic (hypersensitive) to any antibiotic belonging to the macrolide antibiotic subgroup (eg erythromycin, clarithromycin, josamycin).

Warnings and precautions

Talk to your doctor or pharmacist before taking Tacni:

  • You will need to take Tacni every day for as long as you need immunosuppression to prevent rejection of the transplanted organ. You must keep in regular contact with your doctor.
  • While you are receiving Tacni, your doctor may occasionally want to do several tests (eg blood, urine, heart function, vision, and nerve function). This is completely normal and will help your doctor determine the appropriate dose of Tacni for you.
  • Avoid taking (traditional) herbal medicines, e.g. St. John’s wort (Hypericum perforatum) or any other herbal product as these may affect the effect and dose of Tacni that you need to take. If you are unsure, consult your doctor before taking any herbal product or any such medicine.
  • If you have liver problems or have had a disease that may have affected your liver, tell your doctor as this may affect the dose of Tacni you receive.
  • If you get severe abdominal pain with or without other symptoms, such as chills, fever, nausea, or vomiting.
  • If you get diarrhea for more than a day, tell your doctor because it may be necessary to adjust your Tacni dosage.
  • If you have or have had a change in the heart rhythm known as “QT prolongation”, presence of “QT prolongation” in the family, heart failure, low heart rate, electrolyte disturbances, or if you take medicines that prolong the QT interval or that cause electrolyte disturbances
  • When taking Tacni, you should limit your exposure to sunlight and UV light by wearing appropriate protective clothing and sunscreen with a high SPF. This is because there is a possible risk of malignant skin changes during immunosuppressive drug treatment.
  • If you need to be vaccinated, tell your doctor in advance. Your doctor will advise you on the best course of action.
  • Patients treated with Tacni have been reported to have an increased risk of developing lymphoma (see section 4). Consult your doctor for specific advice about these disorders.

Contact your doctor immediately if during treatment you suffer from:

  • problems with your vision such as blurred vision, changes in color vision, difficulty seeing details, or if your field of vision becomes restricted.

Other medicines and Tacni

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Tacni must not be taken together with ciclosporin.

Blood concentrations of Tacni may be affected by other medicines you are taking and blood levels of other medicines may be affected by your taking Tacni, which may mean that the dose of Tacni may need to be increased or decreased. You should especially tell your doctor if you are taking or have recently taken medicines such as:

  • nilotinib and imatinib (used to treat certain cancers)
  • mycophenolic acid, which is used to suppress the immune system to prevent rejection of the transplanted organ
  • medicines for stomach ulcers and acid reflux (eg omeprazole, lansoprazole, or cimetidine)
  • antiemetics used to treat nausea and vomiting (eg metoclopramide)

Tacrolimus passes into breast milk. Therefore, you should not breastfeed while taking Tacni.

Driving ability and use of machinery

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and side effects. Description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.

Tacni contains lactose and sodium

Tacni contains lactose . If you have an intolerance to certain sugars, you should consult your doctor before taking this medicine.

How to take Tacni

Always take this medicine as directed by your doctor. Ask your doctor or pharmacist if you are unsure.

Make sure you get the same tacrolimus medicine every time you pick up your prescription unless your transplant doctor has decided that you should switch to a different tacrolimus medicine.

This medicine should be taken twice daily. If the appearance of the medicine is not the same as usual or if the dosage instructions have changed, talk to your doctor or pharmacist as soon as possible to make sure you have received the correct medicine.

The starting dose to prevent rejection of your transplanted organ is determined by your doctor and calculated according to your body weight. The starting doses immediately after transplantation are normally in the range of 0.075 – 0.30 mg per kg of body weight per day, depending on which organ was transplanted.

Does one depend on your general condition and on what other immunosuppressive medication you are taking? Regular blood tests are required by your doctor to determine the correct dose and to adjust the dose from time to time. The dose is usually reduced by the doctor when your condition has stabilized. Your doctor will tell you exactly how many capsules to take and how often.

Tacni is taken orally twice daily, usually in the morning and in the evening. You should take the capsule on an empty stomach or at least 1 hour before or 2 to 3 hours after a meal. The capsules should be swallowed whole with a glass of water. Avoid grapefruit and grapefruit juice while taking Tacni.

Do not swallow the desiccant contained in the aluminum bag.

If you have taken too much Tacni

If you have ingested too much medicine or if, for example, a child has ingested the medicine by mistake, contact a doctor or hospital for an assessment of the risk and advice.

If you forget to take Tacni

Do not take a double dose to make up for a missed dose.
If you forget to take your capsules, wait until it is time for your next dose and then continue as usual.

If you stop taking Tacni

Stopping treatment may increase the risk of rejection of your transplanted organ. Do not stop your treatment until your doctor tells you to.
If you have further questions about this medicine, contact your doctor or pharmacist.

Possible side effects

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

Tacni reduces your body’s own defense mechanisms to prevent you from rejecting the transplanted organ. As a result, your body will not be as good as usual at fighting infection. If you take Tacni, you may therefore get more infections than usual, such as infections in the skin, mouth, gastrointestinal tract, lungs, liver, urinary tract, and nervous system.

Serious side effects, including those listed below, may occur. Contact your doctor immediately if you have or suspect you may have any of the following serious side effects:
