I went from 1x daily lantus to 1x daily tresiba… Same dose initially but have over time tweaked it a little.
Couldn’t be happier with it. I didn’t really have any specific problems with lantus but tresiba is just vastly better.
No hardships with transitions at all-- just took tresiba one day instead of lantus and never looked back. It’s easy, don’t over think it (several posters here have switched, some seemed to want to make a big complex ordeal of it)
Give it a few days without changing anything. Take it every day 1x with whatever your total daily lantus dose was. It takes a couple days to reach a steady state in your body…
I think you’ll love it.
