No, shortness of breath isn’t a direct side effect of Tresiba. But it’s a possible symptom of heart failure.
Heart failure has been reported when Tresiba is used with a type of diabetes drug called a thiazolidinedione. Examples of thiazolidinediones include Actos (pioglitazone) and Avandia (rosiglitazone).
If you’re prescribed other diabetes drugs to take with Tresiba, talk with your doctor to make sure they’re safe to use together.
