My biggest side effect is dry mouth. Do have itching sometime but that is just being a diabetic I figured. It was so much better then lantus. Even tried trojeo that didn’t last long enough. So for now doing my tresiba while I use my pens. I heard that sometimes there an issue if you combine novolog with it or humalog. Been lucky with my humalog
I had a reaction to tresiba, I started to retain water about a week after starting with it. I gained approximately 10 pounds in 3 days. I was advised to stop using it immediately. Not sure why I reacted this way? I do think most people have a wonderful experience on it. I was just unlucky with it.
