1. What Mycamine is and what it is used for

Mycamine contains the active substance micafungin. Mycamine is called an antifungal medicine because it is used to treat infections caused by fungal cells.

Mycamine is used to treat fungal infections caused by fungal or yeast cells called Candida. Mycamine is effective in treating systemic infections (those that have penetrated within the body). It interferes with the production of a part of the fungal cell wall. An intact cell wall is necessary for the fungus to continue living and growing. Mycamine causes defects in the fungal cell wall, making the fungus unable to live and grow.

Your doctor has prescribed Mycamine for you in the following circumstances when there are no other suitable antifungal treatments available (see section 2):

  • To treat adults, adolescents and children including neonates who have a serious fungal infection called invasive candidiasis (infection that has penetrated the body).
  • To treat adults and adolescents ≥ 16 years of age who have a fungal infection in the gullet (oesophagus) where treatment into a vein (intravenous) is appropriate.
  • To prevent infection with Candida in patients who are having a bone-marrow transplant or who are expected to have a neutropenia (low levels of neutrophils, a type of white blood cell) for 10 days or more.

2. What you need to know before you use Mycamine
Do not use Mycamine
  • if you are allergic to micafungin, other echinocandins (Ecalta or Cancidas) or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

In rats, long-term treatment with micafungin led to liver damage and subsequent liver tumours. The potential risk of developing liver tumours in humans is not known, and your doctor will assess the benefits and risks of Mycamine treatment before starting your medicine. Please tell your doctor if you have severe liver problems (e.g. liver failure or hepatitis) or have had abnormal liver function tests. During treatment your liver functions will be monitored more closely.

Talk to your doctor or pharmacist before using Mycamine

  • if you are allergic to any medicine.
  • if you have haemolytic anaemia (anaemia due to breakdown of red blood cells) or haemolysis (breakdown of red blood cells).
  • if you have kidney problems (e.g. kidney failure and abnormal kidney function test). If this happens, your doctor may decide to monitor your kidney function more closely.

Micafungin may also cause severe inflammation/eruption of the skin and mucous membranes (Stevens-Johnson syndrome, toxic epidermal necrolysis).

Other medicines and Mycamine

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

It is especially important to inform your doctor if you are using amphotericin B desoxycholate or itraconazole (antifungal antibiotics), sirolimus (an immunosuppressant) or nifedipine (calcium channel blocker used to treat high blood pressure). Your doctor may decide to adjust the dose of these medicines.

Mycamine with food and drink

Pregnancy and breast-feeding

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

Mycamine should not be used during pregnancy unless clearly necessary. If you use Mycamine you should not breast-feed.

Driving and using machines

Micafungin is unlikely to have an effect on driving or using machines. However some people may feel dizzy when taking this medicine and if this happens to you, do not drive or use any tools or machines.
