What do you have to consider before using it?

Do not take Myfenax

  • if you are allergic (hypersensitive) to mycophenolate mofetil, mycophenolic acid or any of the other ingredients of Myfenax. if you are breast-feeding.

Take special care with Myfenax

You should inform your doctor immediately:

  • if you experience any evidence of infection (e.g. fever, sore throat), unexpected bruising and/or bleeding.
  • if you have or ever have had any problems with your digestive system, e.g. stomach ulcers.
  • if you are planning to become pregnant, or if you fall pregnant while taking Myfenax.

Myfenax reduces your body?s defence mechanism. Because of this, there is an increased risk of skin cancer. Therefore you should limit your exposure to sunlight and ultra violet (UV) light by wearing appropriate protective clothing and using a sunscreen with a high protection factor.

Taking other medicines

Please inform your doctor or pharmacist if you are taking or have recently taken any other medicines, even those not prescribed.

If you answer yes to any of the following questions talk to your doctor before you start to take Myfenax:

  • Are you taking any medicines containing: azathioprine or other immunosuppressive agents (which are sometimes given to patients after a transplant operation), cholestyramine (used to treat patients with high blood cholesterol), rifampicin (antibiotic), antacids, phosphate binders (used in patients with chronic kidney failure to reduce the absorption of phosphate), or any other medicines (including those you can buy without a prescription) that your doctor does not know about?
  • Do you need to receive vaccines (live vaccines)? Your doctor will have to advise you what is indicated for you

Taking Myfenax with food and drink

Taking food and drink has no influence on your treatment with Myfenax.

Pregnancy and breast-feeding

Use of Myfenax during pregnancy may cause miscarriage or damage to your unborn baby (abnormal development of ears for example).

If you plan to become pregnant, discuss with your doctor alternative medicines to best prevent rejection of your transplanted organ. In certain situations, you and your doctor may decide that the benefit of taking Myfenax for your health is more important than the possible risks to your unborn baby.

If you become pregnant while taking Myfenax, do not stop taking it, but tell your doctor about your pregnancy as soon as possible.

Do not take Myfenax if you are:

  • Breast-feeding
  • Pregnant (unless your doctor clearly tells you)

Tell your doctor straight away if:

  • You think you may be pregnant
  • You are breast-feeding
  • You plan to start a family in the near future

You must always use an effective method of birth control:

  • Before you start taking Myfenax
  • During the entire treatment with Myfenax
  • For 6 weeks after you stop taking Myfenax

You should talk to your doctor about the most suitable method for birth control for you based on your individual situation.

Women who are capable of becoming pregnant must have a negative pregnancy test BEFORE starting treatment with Myfenax.

You are a woman who is not capable of becoming pregnant if any of the following applies to you:

  • You are post-menopausal, i.e. at least 50 years old and your last period was more than a year ago (if your periods have stopped because you have treatment for cancer, then there is still a chance you could become pregnant).
  • Your fallopian tubes and both ovaries have been removed (bilateral salpingo-oophorectomy).
  • Your uterus has been surgically removed (hysterectomy).
  • You have premature failure of the ovaries, confirmed by a specialist gynaecologist.
  • You have been diagnosed with one of the following rare conditions that some patients are born with that make pregnancy impossible: the XY genotype, Turner`s syndrome or uterine agenesis.
  • You are a child/teenager who has not started having periods, and cannot become pregnant.
