Hi, I took Lantus during my first pregnancy & whilst I have a lovely little boy to show for it, Lantus was not a good insulin choice for me whilst pregnant or not pregnant. I was transferred onto it 2 months prior to pregnancy & for the first time in my adult life I suffered uncontrollable hypos, no matter what intervention action taken.....splitting the dosage, reducing the dosage well below any other basal in my adult life, etc. It took until post pregnancy & for me to invest in a private diabetic consultant & freestyle libre to prove that it simply was not a safe insulin choice for me.
Due to my hypos, I was induced early at 35wks, because my son had not been growing quite as expected, but he was OK despite a bit of jaundice & weighed 5lb. He just turned 3 in the past couple of weeks & is a physically healthy boy.
If however you have been OK on Lantus since taking it, this is the most important indicator of how your body responds & how it is likely to respond in pregnancy. As I said, in the 2 months I used Lantus pre-pregnancy the issue for me was already evident. Now I have an insulin pump with Novorapid insulin which, as far as I am concerned is, very much tried & tested as I have taken it most of my adult life.
I am pregnant again at the moment & an insulin pump with Novorapid has made this pregnancy so far much more manageable for me.
