Thanks all!
It's a pill form, not liquid. I didn't think of it until now, can't check with vet, they are closed until Monday and I have to start them now.
She is extremely sensitive to meds, vet had a hard time thinking of a antibiotic to put her on, so I don't know if he would take that (increase/decrease in BG) into consideration, he was just trying to think of something she may not get sick from.
If it did effect BG, would it increase or decrease it, would you think? Her shot is due in 4 hours.
