Forms and strength of NovoLog

NovoLog is a liquid solution that’s injected under your skin or into your vein. It comes as follows:

  • Forms:
    • 3-mL PenFill prefilled cartridge used with a reusable insulin pen
    • 3-mL FlexPen prefilled pen, which is disposable (this replaced the NovoLog FlexTouch prefilled pen)
    • 10-mL multiple-dose vial used with syringes or an insulin pump
  • Strength: 100 units per milliliter (mL)

NovoLog can also be given by intravenous (IV) infusion (an injection given into your vein over time). This is usually given by a doctor or another healthcare professional in a hospital.

Dosage of NovoLog

This article describes the recommended dosages for NovoLog. The drugmaker provides these dosages.

If your doctor prescribes this medication, you should follow the dosage they prescribe. Your doctor will determine the dosage that best meets your needs. Do not change your dosage of NovoLog without your doctor’s recommendation.

Usual recommended dosages of NovoLog in adults

Usually, doctors start by prescribing a low dosage of NovoLog. Then, they’ll adjust it over time until the right dosage is reached. Ultimately, your doctor will prescribe the smallest dosage of NovoLog that gives the desired outcome.

For forms that are injected under your skin, NovoLog should be injected:

  • within 5–10 minutes before a meal
  • under the skin of your upper arm, abdominal area, thigh, or buttocks

For continuous infusion under your skin with an insulin pump, your doctor will recommend the best NovoLog dosage for you.

For IV infusion, NovoLog is given by a doctor or another healthcare professional in a hospital. This is because your blood sugar level and certain electrolyte levels would need to be closely monitored.

Talk with your doctor if you have questions about your NovoLog dosage.

Dosages of NovoLog in children

NovoLog can be prescribed to children ages 6 years and older with diabetes. The dosage for this use is the same as the dosage for adults above.

Dosage adjustments for NovoLog

  • other medications you take
  • other health conditions you may have

Your doctor will prescribe the dosage of NovoLog that’s the best for you based on the factors above. Different types of insulin dosages that your doctor may prescribe include:

  • Sliding scale dosage: With a sliding scale dosage, your dose will vary based on what your blood sugar level is at a specific time.
  • Preset dosage: With a preset dosage, your doctor will prescribe the exact amount of insulin for you to use at a specific time.
