hi, welcome
I don't ave lupus, but I've asthma and I do take steriods inhaler twice a day as well
as ventolin when I need to, some times Prediszone. apart from having the munchies when I'm unwell, I don't see any difference with blood glucose so far, it doesn't get any higher or lower it stays between 7-8 mml. For the last week I've been taking inhalers up to 8 times a day. I've only had diabetes for 2 weeks, hopefully someone will be along who have had lupus to give you more information.
