Detailed Answer:
Hello and thank you for asking!
Of course while on treatment with corticosteroids the Diabetes treatment should be modified or started a few hours after the injection.
If you haven't been diagnosed with Diabetes ( the glucose level has been XXXXXXX before the injection) you need only one injection for treatment, than the glucose levels will get back to normal within 24-48 hours.
Otherwise you need to see a physician to start treatment.
Try to drink plenty of water and monitor the blood glucose before and after food for 48 hours.
Kind regards,

I am not on any medications for diabetes. When you mention "only one injection for treatment", what type injection are you referring to?

As of 1042 a.m., my glucose reading is 185.

Detailed Answer:
Welcome back!

I meant to say the corticosteroid injection. If the treatment with corticosteroids will continue, then you need to see a Diabetologist to get treatment for Diabetes.

If you needed only one-day treatment, then monitor the blood glucose because it should get back to normal within 2-3 days.
