I have been on the pred for three weeks now at 20mg twice a day and I am diabetic! Yes, you guessed it my bg levels have skyrocketed! Last Wednesday my endocrinologist added 5mg of glipizide to my Victoza injection and 1000mg of metformin twice a day, but bg levels are still so high! In the 300s and 400s. I will start my taper once I start Humira. Of course there have been a few insurance issues to deal with, so the earliest I will start will be the end of next week. I am also so dehydrated and constipated, but manic at the same time! Crazy lol! So I am trying to hydrate, watch what I eat and drinking benefiber. I might be taking a trip to the ER later if I can not hydrate myself! Just needed to vent! Thank you!
