What to expect

To know if U-500 is helping to improve your glucose, check your blood sugar.

Low blood sugar is the most common side effect of U-500.

It’s normal to want to understand possible side effects like low blood sugar when starting a new insulin. Be sure to talk to your doctor about the causes and how to identify and manage low blood sugar.

Take your dose 30 minutes before eating a meal as your doctor instructed.

Timing is important to help reduce the risk of low blood sugar (hypoglycemia).

As with any insulin, there is potential to experience low blood sugar at any time, including in the first few weeks as you’re getting used to your new medication or dose. Checking your blood sugar as directed by your doctor will help monitor for any highs or lows, as well as possible improvements in your blood sugar.

Talk with your doctor about how to tell if you have low blood sugar and what to do if this happens while taking Humulin R U-500. Follow your doctor's instructions for treating your low blood sugar.
