I just received an injection and was told it would make my sugar go up. What is too high?
The most common medications given by injection that can cause an increase in blood glucose levels are steroid injections. These are usually given into a joint to reduce swelling and pain. Blood glucose levels can go up quite high after a steroid injection, into the 200s and sometimes into the 300s., with the effect lasting up to 2 to 3 weeks. If your blood glucose level is running over 250 for more than 2 readings in a row, it is good idea to call your doctor’s office and let them know.
