Hi
@Ryann1990, Sorry to hear you are having such hassles.
As a T!D for 52 years, not as professional advice or opinion:
I assume you are about 18 ? If so you may still be experiencing growth spurts which is going to periodically increase your insulin resistance as growing hormones surge for ? 3 weeks or so then drop back. Also your appetite may increase and if that is mainly in carbs that will add further trouble with BSLs.
From about ages 15 to 19 my insulin used to increase x2 to x 3 for 3 weeks or so and then the hypos would start and I would be scrambling to get the doses down.
Unless you have someone advising you who understands this you may not be getting the best advice and any long-acting insulin used may seem to be rubbish.
Having said that there are a lot of posts on various diabetes forums complaining about Tuojeo and the same things you have been experiencing. From what I can work out:
The switch from Lantus to Toujeo is often not a straight swop dose for dose
Some have said that > 50% of Toujeo users develop antibodies to it and this explains its bizarre effects
Some have no apparent problem with Toujeo but it is not clear if these people do or do not have antibodies to it and whether they are all in older life, past growing age or not.
With use of the proper pens for Toujeo there should not be any confusion about dose, provided the person does not decide to spontaneously divide the dose by one third to somehow equate it with lantus
Like Lantus, Toujeo has the same risk of causing severe hypos if accidentally injected into a blood vessel ( a risk not shared by other long-acting insulins, Tresiba or Levemir)
The absorption rate of lantus and Toujeo was reported by the manufacturer to be more reliable than the older NPH insulin.
But data has not supported that finding. I surmise that this is one reason for the difficulties that some have found.
see diattech.com Lantus; Lethal or Lifesaver? # DOC #gbdoc
What to do? Suggestions:
- find a DSN who understands teenage diabetes and that you will not likely be on a stable insulin dose for more than a week or two at a time, until you stop growing
- Toujeo is causing you problems, potentially dangerous ones, discuss changing to something else which is safer all round
- Ask this new DSN if the more flexible insulin for dose changes is levemir because it is a twice a day insulin - 2 chances to get the doses right.? Whilst that means 5 shots per day flexibility with your growth is key to better BSLs - does she agree or not?
- ask about what to do with diet during growth spurts ? more protein rather than carbs maybe?
- ask about what measure to take with food and insulin for exercise
Best Wishes for a better future. Keep growing and learning, I still am !!
