Your doctor will do blood tests before each cycle of Lonsurf. You start a new cycle every 4 weeks. The tests are needed because Lonsurf can sometimes affect your blood cells.

This medicine is not indicated for use in children and adolescents below the age of 18 years. This is because it may not work or be safe.
