Dear members, I usually post on the Lantus/Levemir forum. Macka has been in the reds and blacks for 2 months now, with only a few blues here and there. My vet thinks that Lantus does not work for him and advised to switch to Prozinc. I asked about Levemir and she was not opposed either. I don't know what to do! Right now I'm just increasing the dose but without much results... Has anyone of you switched from Lantus to Prozinc? And why? Are you more satisfied? What are the pros? All insights are appreciated in order for me to make the best choice for my baby. Thank you!!
