Measuring Your Results

By now you probably already know a lot about NovoLog®. It is a fast-acting insulin taken at mealtime proven to help control blood sugar, and it is changed slightly so that it acts more quickly than regular human insulin. That is why it is called analog insulin. And you may even know that controlling your blood sugar at mealtime, your postprandial blood sugar, can help lower your A1C. But you may not be sure how well your NovoLog® therapy is working for you right now. Remember, even though NovoLog® is a “fast-acting insulin,” that term refers to how fast it works at mealtime. It will take time and effort to bring down your overall blood sugar. But you will want to know how it’s working.

How can you tell? One of the best ways to know how well your insulin is working is to check your blood sugar. Checking your blood sugar, as instructed by your diabetes care team, is the only way to know if your diabetes care plan is working. Even if you feel great, your blood sugar can be higher or lower than it should be. 


Blood Sugar Diary

Many people find using a Blood Sugar Diary to be very helpful in finding out what their blood sugar patterns are. A Blood Sugar Diary will tell you: 

  • If your insulin or other diabetes medicine is working
  • How physical activity and the foods you eat affect your blood sugar


Keeping track of your blood sugar is a very important part of reaching your A1C goal. Use these guidelines from the American Diabetes Association (ADA) to help see if you’re on the right track.


Time Goals for people with type 1 or type 2 diabetes
FPG (at least 8 hours since you’ve eaten, usually when you wake up) 80 to 130 mg/dL
PPG or postprandial blood sugar (1 to 2 hours after you eat) Less than 180 mg/dL
A1C Less than 7%

If you’ve recently started on NovoLog®, please remember that:

  • You may see an effect on your after-meal, postprandial blood sugar (PPG) as you work with your diabetes care team to adjust your insulin doses
  • Your A1C will probably take longer to change. Think of your A1C as a snapshot of your blood sugar control over the last 2 to 3 months
  • NovoLog® is not a quick fix or a temporary solution. Even after your A1C improves you will still need to take it to help maintain control
  • Be patient and keep at it. Diabetes management is a marathon, not a sprint!

Remember, millions of people just like you have already taken NovoLog® to help them get to goal!


If you’ve been taking NovoLog® for a while and your A1C is not at goal, in addition to getting active and watching what you eat, talk to your health care provider about:

  • Adjusting your NovoLog® dose before meals to help cover blood sugar spikes
  • Taking additional doses of NovoLog®, especially if you are not taking it with every meal
  • Shifting your insulin intake to include more bolus and less basal insulin. If you are on basal-bolus therapy, NovoLog® can provide up to 70% of your daily insulin with your basal insulin taking care of the rest
