I have had my insulin pump and been on Humalog for two weeks. I've had a few problems with blood in my cannula, so I changed my inset this morning because my BG has been between 220 and 300 since I changed it the night before. Since I changed my inset this morning my sugar has continued to be between 200 and 300. I got so fed up with the highs I decided to give my self a shot! And after hours and doing this 2 times (using my correction formula), its still isn't working! I have only had this bottle for 2 weeks. I have carried it with me but kept it protected, in the shade, in cool areas. Does Humalog go bad quickly. I have to wait until the pharmacy opens in the morning to get a new bottle, because my doctor put "Dr. must authorize" on the prescription. Does anyone else have this problem?
