What Azathioprine Actavis is and what it is used for

Azathioprine Actavis belongs to a group of medicines called immunosuppressants, which act by inhibiting the body’s immune system and inhibiting cell division. These drugs are used to treat a variety of diseases (such as the skin disease lupus erythematosus) when the immune system needs to be suppressed or after an organ transplant.

Azathioprine contained in Azathioprine Actavis may also be approved for the treatment of 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 use Azathioprine Actavis

Do not take Azathioprine Actavis

  • if you are allergic to azathioprine or any of the other ingredients of this medicine (listed in section 6), or if you are allergic to the substance that azathioprine is broken down in your body (6-mercaptopurine).
  • if you have a serious infection.
  • if you suffer from severe liver or bone marrow dysfunction.
  • if you have pancreatitis.
  • if you are pregnant (unless the benefits outweigh the risks).
  • if you are breast-feeding.

You should not be vaccinated with live vaccines (especially tuberculosis (BCG), smallpox and yellow fever) while you are being treated with Azathioprine Actavis.

Warnings and cautions

Talk to your doctor or pharmacist before taking Azathioprine Actavis:

  • if you have ulceration of the throat, fever, infection, unexpected bruising, bleeding, or other signs of impaired bone marrow function.
  • if you are deficient in the enzyme thiopurine methyltransferase (TMPT).
  • if you suffer from a disease called Lesch-Nyhan syndrome.
  • if you are taking immunosuppressive therapy and taking Azathioprine Actavis, this may increase your risk of:
    • tumor er, including skin cancer. Therefore, when taking Azathioprine Actavis, you should avoid excessive sunbathing and wear protective clothing, and use a sunscreen with a high protection factor.
    • lymphoproliferative disorders
      • Treatment with Azathioprine Actavis increases your risk of developing a type of cancer called a lymphoproliferative disorder. During treatment regimens that contain several immunosuppressive drugs (including thiopurines), this can lead to death.
      • A combination of several concomitant immunosuppressive drugs increases the risk of disorders of the lymphatic system due to a viral infection (lymphoproliferative disorders associated with Epstein-Barr virus ( EBV )).

Taking Azathioprine Actavis may increase your risk of:

  • development of a serious condition called macrophage activation syndrome (excessive activation of white blood cells associated with inflammation ), which usually occurs in people with certain types of arthritis.

The treatment is only given by doctors who are specialists in the field of immunological diseases and by doctors with specialist expertise in your disease.

During the first 8 weeks of treatment, a complete check of the number of blood cells in the blood should be done at least once a week:

  • if you are given a high dose
  • if you are older
  • if you have mild to the moderate liver or bone marrow function
  • if you have impaired kidney function
  • if you have abnormal blood composition

Thereafter, the number of blood cell tests can be done less frequently, approximately once a month or at least once every 3 months. You should be checked regularly if you have severe hepatic impairment.

Careful monitoring of the number of blood cells in the blood is necessary if you are being treated with any of the following medicines at the same time:

  • allopurinol, oxypurinol, or thiopurines (medicines used to treat gout )
  • mesalazine, olsalazine, or sulfasalazine (medicines used to treat intestinal diseases and gout )
  • ACE inhibitors (medicines used to treat high blood pressure )
  • trimethoprim/sulfamethoxazole (medicines used to treat urinary tract infections)
  • cimetidine (a medicine used to treat stomach ulcers )
  • indomethacin (a medicine used to treat gout )
  • drugs with cytotoxic / bone marrow inhibiting effect

If you are going to have surgery, tell your anesthetist that you are using Azathioprin Actavis as it may affect some muscle relaxants used during anesthesia.

You should be carefully monitored if you are also being treated with coumarin-type blood thinners.

Treatment with azathioprine may increase the risk of developing skin cancer. This is especially true of skin areas that are exposed to the sun. You should refrain from sunbathing or using a solarium. Wear protective clothing and a high sun protection factor and check the skin regularly.

You should not leave acute infections untreated. Consult your doctor.

You should be carefully monitored by a doctor if you are being treated with other cancer medicines at the same time.

NUDT15 gene mutation

If you have a hereditary mutation in the NUDT15 gene (a gene that is involved in the breakdown of Azathioprine Actavis in your body), the risk of you getting an infection hair loss is higher and your doctor may give you a lower dose.

Other medicines and Azathioprine Actavis

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

It is especially important that you tell your doctor if you are being treated with the following medicines:

  • allopurinol, oxypurinol, thiopurine, or other xanthine oxidase inhibitors, such as febuxostat (used mainly to treat gout ).
  • ciclosporin or tacrolimus (used to inhibit the immune system).
  • olsalazine, mesalazine, and sulfasalazine (medicines used to treat intestinal diseases and gout ).
  • warfarin and phenprocoumon (blood thinners).
  • ACE inhibitor (used to treat high blood pressure ).
  • trimethoprim/sulfamethoxazole (used to treat urinary tract infections).
  • cimetidine (used to treat stomach ulcers ).
  • indomethacin (used to treat gout.
  • anticancer drugs or other medicines with bone marrow-inhibiting effect.
  • vaccination with the live vaccine (especially for tuberculosis (BCG), smallpox and yellow fever).
  • killed (weakened) vaccines ( hepatitis B; jaundice that is transmitted through the blood).
  • infliximab (a medicine used to treat Crohn’s disease ).

Before undergoing surgery, tell your anesthetist that you are being treated with azathioprine, as the muscle relaxants used in anesthesia may affect or be affected by azathioprine.

Inform your doctor. Dose one may need to be adjusted.

Talk to your doctor before starting treatment as there are risks associated with Azathioprine Actavis. You may need regular check-ups for side effects and side effects throughout treatment with Azathioprine Actavis.
