1. What is Filsuvez and what is it used for

Filsuvez gel is a herbal medicine that contains dry extract of birch bark.

It is used for the treatment of wounds in adults and children (from 6 months of age) who suffer from a type of disease called "epidermolysis bullosa" (EB), specifically "dystrophic" (DEB) or "junctural" (JEB). This is a condition where the outer layer of the skin separates from the inner layer, making the skin very fragile and causing wounds to appear.

  • red, hot, swollen, or increasingly painful skin around the wound.

If you have a wound infection, you may need to stop using Filsuvezand another treatment may be necessary. Your doctor or nurse will tell you if Filsuvez treatment can be restarted once the infection has cleared up.

People with EB are more likely to develop a type of skin cancer called "squamous cell carcinoma" (SCC). If you are diagnosed with skin cancer while using Filsuvez, you should talk to your doctor or nurse and stop using Filsuvezon that part of the skin.

Filsuvez does notcontain birch pollen, so it can be used in people with a birch pollen allergy.
