For Type 2 Diabetes "I was on Lantus, which worked beautifully for me. Like others, I was switched to Basaglar (not my doing). The issue I am having is that my appetite seems to have doubled. In a matter of two months, I went from 188lb to 201lb. I know my diet as a diabetic is a delicate one. I have had no other changes in my meds whatsoever. This has occurred since I started this insulin. I hate it!!! Am I the only one that experienced this issue?"

For Type 2 Diabetes "My insurance company switched me to this, and I have gone from my usual blood sugar of 90 to 120 to this morning 435. I have had muscle pain, night cramps, increased appetite, and weight gain. I hate this, and I am on my way to the emergency room because of it. I feel a lawsuit coming on. I think this is an experimental drug, and it’s hurting a lot of people. It's a shame the greed that exhibits itself in the drug industry."

For Diabetes, Type 1 "I've been type 1 for 20 years and been on Lantus the majority of the time. My insurance switched me to Basaglar 4 months ago, and I've gained 20 lbs. I also have had headaches, and I already suffer from anxiety and depression, but my depression seems to be a lot worse. DO NOT RECOMMEND!!! If I could give it a 0 out of 10, I would!"

For Type 2 Diabetes "My doctor placed me on this medication three months ago, and I immediately began noticing that I was having trouble staying asleep at night and waking with a dull headache every morning. I also noticed occasional and always unexplainable perspiration on my face and scalp. After about a month of use, lower leg swelling and shortness of breath was added to my symptoms. Upon calling my doctor, I was advised to 'stick with the Basaglar' and that it would 'get better.' And so, I tried. Then I began noticing my weight rapidly increasing and rushed to see my doctor in person. He wasn't there, but his PA immediately said that Basaglar is the culprit for all my ills, including the weight gain, and took me off this terrible med. We are now searching for something that will work in its place. The loss of quality of life just wasn't worth the small amount this medication lowered my A1C."

For Diabetes, Type 1 "I have been diabetic for 24 years and have used Lantus for about 20 years until my insurance said this winter that it would not cover it. I was changed to Basaglar and told that it was “basically the same,” but it's not!!! In 8 months, my A1C has jumped to a 10% from a 7-8%. My blood sugar drops really low in the morning without real explanation, and then it creeps up to ridiculously high levels no matter what I eat. I am very low carb and I exercise, but nothing helps. I am also unable to lose weight, and I feel terrible. This medication is a disgrace!! If you can even call it that. I am glad to see that I’m not alone in having these issues."

For Type 2 Diabetes "Seems almost everyone was switched off insulin that works to Basaglar in 2016. I take 90 per day in addition to 1000 metformin twice a day and fast-acting up to 3x a day. When I started Basaglar, it seemed to work. It gradually started being less effective, it is now like I am using water. My mornings were running up to 90, they now run up to 200. In 2021, I started itching on all the soft parts of my skin, shoulder pains, fatigue, sleeping issues, and weight gain. I have discussed issues with my doctor, he doesn't feel that Basaglar is the issue. I go to see him in a month, it's time to demand a change."

For Diabetes, Type 1 "My experience with Basaglar will affect me for the rest of my life, and not in a good way. Of course, I doubt there is a doctor that will say results are due to this horrible 'biosimilar' creation, but I developed heart failure from Basaglar. All started when I went to see a doctor in an area I had just moved to. Without any discussion or notification, they put me on Basaglar, no change in the number of units that I needed to take. I was on it for a month before I started to feel my worst. Then I looked closer at the medication and realized it was not Lantus, which I had been taking for years. I gained 40 pounds. I could not sleep in my bed anymore because I couldn't breathe. My feet were swollen drastically. I could not make it up 13 steps without having to stop multiple times because I could not breathe. I was a very active person before all of this. After multiple trips to the doctor and a change in doctors, they found that my ejection fraction was 15%. Normal is 55-75%."
