Semaglutide (Ozempic) for the treatment of type 2 diabetes


Semaglutide (trade name: Ozempic) has been approved in Germany since February 2018 for the treatment of type 2 diabetes in adults who can't lower high blood sugar levels enough through exercise and diet alone. It can be combined with other blood-sugar-lowering drugs such as metformin, sulfonylurea or insulin, and is also an option if metformin isn't well tolerated.

Diabetes is a metabolic disease that affects many different parts of the body. In type 2 diabetes, the pancreas still produces enough insulin at first, but the body’s cells gradually lose the ability to absorb and use the insulin. If the blood sugar levels can't be lowered enough by diet changes and exercise, medications are used to regulate them.

Semaglutide helps to prevent strong fluctuations in blood sugar levels and the unpleasant effects of high and low blood sugar. A further goal of this treatment is to prevent long-term complications that may arise if blood sugar levels are too high.


Semaglutide is injected under the skin once a week (with or without meals) using a pre-filled pen. The dose prescribed will depend on a number of factors, including previous blood-sugar-lowering treatment, blood sugar levels and the target blood sugar level. It has to be adjusted individually.

Other treatments

Type 2 diabetes can be treated with a number of different medicines, either alone or in combination with each other. These medicines include metformin, sulfonylurea and insulin.


In 2019, the Institute for Quality and Efficiency in Health Care (IQWiG, Germany) looked into the advantages and disadvantages of semaglutide compared with the standard treatments for people with type 2 diabetes.

But the manufacturer didn’t provide any suitable data with which to do the assessment.
