I have a dietetic 11 yr old boy, he was on Lantus at 5 mL every 12 hours. Then he started acting weird and nervous and very lethargic. I took him to the vet a different vet then I normally go to because they were booked, and his sugars levels were high so he put him on Vetsulin and they did a glucose curve and he went up and down. So now he’s on an Vetsulin at 3 ml and he’s acting lethargic again. Oh and on KD food for his kidneys, the vet said he’s border on having issues with that. I take him back to the vet on Thursday to get another glucose check to see if they need to up his insulin to 4 mL. I do not have a glucose kit. And I’m not sure how to do it. Just not sure what to do, hate seeing him so out of it, so any advice is appreciated.....thanks!
