I'm posting for my mom who has an uninformed vet: "give 3.5 units, don't test and call me in 3 weeks" and Mom has no internet access and lives in a different state than me. I've gotten some help before from FDMB for her and Francis. He is about 14-15 years old and on PZI. He is also hyperthyroid and on meds for that. Looks like the insulin is finally working; it took her a while to get him on the right dose. She's switched to wet food but still has a 13% carb dry food out because she's got 3 other cats and can't switch to all wet for many reasons. My question is about PZI. I know nothing about it and it seems his numbers are bizarre and he may be ready for a dosecrease. Is it the same as Lantus, if his BG hits <50, go down by .25? Here are his numbers: Saturday: AMPS=447, +2=465, +4=292, +6=74 (she gave syrup cuz he's never been that low), +6.75=103, +9=226, PMPS=330 Sunday: AMPS=362, +6=62 I told her to watch him and test to see where he goes from here. The thing is that she will be working tomorrw and will not be able to get a +6. Any thoughts on course of action?
