Hi all! I brought River home yesterday from the veterinary ER with 2 prescriptions, one for Lantus and the other for Humulin. After spending $4,000 from Saturday on I just couldn't stomach $350 on the Lantus, so Humulin it is. She's 2 doses in after a couple of days' worth of IV-administered insulin at the vet, and I'd love any advice you can offer me about this regimen. Are there any particular pros/cons to this insulin vs. others? Anything I should know?
