No, Tresiba doesn’t cause eye problems as a side effect.
However, blurry vision can be a symptom of hypoglycemia (low blood sugar levels). And hypoglycemia is the most common side effect of all insulins, including Tresiba.
If you have blurry vision while using Tresiba, it may be a sign of hypoglycemia. Before using the drug, your doctor may describe what to do if you develop hypoglycemia symptoms, including blurry vision. You can also learn more about the symptoms and treatment of hypoglycemia in the “Side effect specifics” section below.
While using Tresiba, if you experience blurry vision that you think might not be caused by hypoglycemia, talk with your doctor. They’ll work with you to determine the cause and the best way to treat your blurry vision.
