Interesting, N17. I've taken insulin for over 40 years, and Lantus is truly unique, although more expensive than the other long-acting insulins.
What makes Lantus unique is that it doesn't peak. Since starting on Lantus, for the first time in my life I'm not experiencing insulin reactions that require glucogon. It's really a life-changing insulin for long-term diabetics who can end up with hypoglycemic unawareness. For years I didn't have any symptoms of insulin shock until I past the stage where I could treat it myself.
That said, it isn't perfect. My A1c's have been higher and IMO it's more difficult to acheive tight control that it was with Humalin L. I'm not sure why. I think one has to be more aggressive with the Humalog when using Lantus. It's easier to get a bit lazier with Lantus.
I still think it should be covered anywhere that Humalin L or NPH is covered. The patient should be able to choose. Lantus again -- is absolutely unique and many patients with various problems with insulin shock absolutely need it IMO. I hope Australians have a diabetes association or similar group waging an organized battle to get the policy reversed.
