Treatment with glucagon-like peptide-1 analogues including liraglutide is a new treatment option for patients with type 2 diabetes. Treatment with liraglutide decreases HbA1c by 1-2%, and additionally liraglutide has a reducing effect on weight, lipids and blood pressure. Most adverse events are related to the gastrointestinal system and most often they disappear within a few weeks. The risk of major hypoglycaemic episodes is minimal. Long term data on treatment and adverse events with liraglutide are still lacking.
