Treatment Decisions: Beyond The Basics - Dexcom G5 MOBILE User Manual

Watch and Wait
Be patient. Insulin takes time to work.
It's tempting to correct an ongoing high blood sugar; however, taking insulin doses too close
together, or "stacking" insulin, is a common cause of low blood sugars.
So what should you do?
Rapid-acting insulin may not start working until 15 minutes after dosing. It works hardest
typically one or two hours later, staying in your system four or more hours. If you inject
another corrective dose within that time frame, it could result in low blood sugar. You do
want to respond to a high glucose reading between meals; just be careful not to overreact.
Talk with your HCP about what you should do if you are high between meals.
Don't worry—If you take insulin to cover what you eat, you're not stacking insulin. Talk to
your HCP to help you decide the best action to take.
After meeting with your HCP, you should be ready to use the Dexcom G5 for treatment
decisions. But do you know why? The next section explains the whys and hows of using your
