Lantus Side Effects


I was diagnosed with T1 Diabetes a little less than 3 months ago.  I was lucky to catch it during the "honeymoon period" and so far I have only had to take 4 units of Lantus in the morning, which combined with a low carb diet, and a partly working pancreas, I have easily been able to control my BS.  It's always between 80 and 120 at the highest after meals.

My biggest issue so far is that about 2 weeks after I started Lantus, I began to feel extremely fatigued all the time.  I have a difficult time concentrating, and my short term memory is suffering as well.  It has affected my work, my social life, and my overall metal wellbeing.  

My endocrinologist has tested my iron levels, thyroid and cortisol levels, and everything has come back normal.  I am beginning to think it could be the Lantus... has anyone else experienced such side effects on Lantus?  Has anyone switched types of insulin, and felt different because of it?

Please help! Thanks

I've not heard of this, but with diabetes anything is possible.  

Do you know what your blood sugar was when you were diagnosed?  I'm wondering if you are tired because your body is adjusting to your new, lower blood sugar.  

Another possible cause may be your low carb diet.  Carbs are the best form or energy and our brains exclusively run on glucose.  Our bodies can make glucose and convert protein into glucose, but it's less efficient and some people do better on low carb diets than others.  You might need to work with your doctor or a nutritionist to find exactly the right carb levels to meet your energy needs without making blood sugar too high.  If you're eating low carb you have to drink lots of water too.

It sounds like you are doing really well for being so new to diabetes.  If you haven't read it, check out Riva Greenberg's book "50 Diabetes Myths That Can Ruin Your Life; And the 50 Diabetes Truths That Can Save It." Gives a quick, comprehensive overview of modern diabetes management.

That is very interesting. I have been on Multiple Injections and have taken Lantus since my diagnosis (10 years ago). I have never had an issue like this. I agree with jennagrant though that it could be the low carb diet.

Also, I take my Lantus at night. I have no medical experience etc, but just wondering If it is the Lantus, maybe try changing the time when you take it. It could be that since your taking it in the morning, that it is effecting you during the day. Maybe try it at night? I would talk to your doctor about it.

Your numbers are great, and you should not have to feel fatigued because of great numbers! Good luck with everything, and hopefully you're able to figure it out!
