I have a friend who has been Type 1 many years. She was switched from Lantus to Levemir in January for insurance purposes. She had no problems with Lantus and had good BG control, but is now having problems with her BG control on Levemir. She has been having little welts around the injection locations that hurt badly as if she's been bruised. She is wondering if it's a side effect or if others have had allergic reactions? Has anyone else has issue with lesser control of BG after switching insulins?
