Using an Insulin Pump

NovoLog® has been proven safe and effective for use in insulin pumps in children ages 2 and older with type 1 diabetes and adults with type 1 and type 2 diabetes. 

Many people with type 1 diabetes use an insulin pump.


What is an insulin pump?

An insulin pump is a small, programmable, battery-operated device that delivers a steady, measured amount of insulin under your skin.

You and your diabetes care team can program your insulin pump to deliver NovoLog® in constant “basal” doses throughout the day and “bolus” doses at mealtime.

Insulin pumps may be helpful for people with diabetes who have more than one insulin injection per day, including some people with type 2 diabetes.

Pumps provide continuous insulin delivery in small doses, similar to the way the pancreas naturally releases basal insulin. You push a button to release mealtime doses of insulin to cover food. They allow people with diabetes to take their insulin automatically, wherever they happen to be.


Benefits of NovoLog® in an insulin pump

NovoLog® is a fast-acting insulin that can be used for up to 6 days in a pump before it needs to be changed. The table below shows how often to change NovoLog® in a pump. Please be sure to check the instructions that came with your pump.

Pump component Time frame before changing
NovoLog® in reservoir Up to 6 days
Infusion set and infusion set insertion site Up to 3 days

NovoLog® in the pump should be discarded after exposure to temperatures that exceed 98.6ºF.


Low rate of clogs in an insulin pump

In a clinical study, NovoLog® was found to have a low rate of clogs when used in pumps. That's good news if you are already using, or thinking about using, an insulin pump.

NovoLog® remains heat stable in pumps at normal body temperature (up to 98.6°F). This makes NovoLog® a good choice for people who wear their pumps beneath their clothing and close to their bodies. Many people do this to make their pumps less visible and to keep them more protected.


NovoLog® in an insulin pump offers:

  • Heat stability. NovoLog® maintains heat stability in pumps at normal body temperatures (up to 98.6°F)
  • Low rate of clogs (also called occlusions). NovoLog® in a pump has been proven to have a low rate of occlusions
  • Extended storage. NovoLog® can be stored in the pump reservoir for up to 6 days before being changed


Things to keep in mind when using NovoLog® in an insulin pump

  • When NovoLog® is used in insulin pumps, it should not be diluted
  • Because NovoLog® works fast, it should be infused within 5 to 10 minutes before a meal
  • Infusion sites should be rotated within the same area to reduce the risk of skin thickening or pitting at the injection site (called lipodystrophy)
  • You and your diabetes care team will program the pump to deliver about the same daily amount of insulin that you had been taking before. Although it’s different from person to person, about 50% of the total daily insulin requirement is usually taken as boluses before meals. The rest is programmed as a background, or basal, infusion
  • You will need to change the NovoLog® in the pump reservoir at least once every 6 days or after exposure to temperatures that exceed 98.6ºF
  • You should change the infusion sets and the infusion set insertion site at least every 3 days


The following insulin pumps have been used in studies conducted by Novo Nordisk, the manufacturer of NovoLog®:

  • Medtronic Paradigm® 512 and 712
  • MiniMed 508
  • Disetronic® D-TRON® and H-TRON®


Before using a different insulin pump with NovoLog®, read the pump label to make sure the pump has been evaluated with NovoLog®.

If you use an insulin pump, it’s a good idea to have a backup source for insulin. Ask your diabetes care team if NovoLog® FlexPen®—or NovoPen Echo®—which offers half-unit doses—could be a good option for you.

Even if you already use a different delivery system, it’s always good to know back-up options for delivering NovoLog®
