interferon beta-1b

This medicine is authorised for use in the European Union.


Betaferon is a medicine used to treat adults who have multiple sclerosis (MS). MS is a disease in which inflammation damages the protective insulation around nerves (demyelination) as well as the nerves themselves. Betaferon is used in patients:

  • who have experienced the signs of MS for the first time, and these are severe enough to need treatment with injected corticosteroids (anti-inflammatory medicines). Betaferon is used when the patient is considered to be at high risk of developing MS. Before using Betaferon, doctors need to exclude other causes for the symptoms;
  • who have MS of the type known as ‘relapsing-remitting’, when the patient has attacks (relapses) between periods with no symptoms (remissions), in patients with at least two relapses within the last two years;
  • who have secondary progressive MS (the type of MS that comes after relapsing-remitting MS), when their disease is active.

Betaferon contains the active substance interferon beta-1b.
