What strength does NovoLog come in?
NovoLog comes in a strength of U-100. This means it contains 100 units of insulin per 1 milliliter (mL) of solution.
What are the usual dosages of NovoLog?
Your doctor will ultimately prescribe the smallest dosage of NovoLog that will manage your blood sugar levels.
The manufacturer of NovoLog doesn’t provide specific dosage recommendations, a dosage calculator, or maximum dose information for NovoLog. Your dosage will depend on whether you have type 1 or type 2 diabetes, as well as your blood sugar levels, weight, diet, and other factors.
When you first start using NovoLog, your doctor will calculate your dosage according to these factors. They’ll show you how to adjust your dosage based on these factors and any changes to your diet.
Your doctor will also demonstrate how to give yourself a dose. For more information, see the “How is NovoLog given?” section below.
As a general recommendation for type 1 diabetes, the American Diabetes Association (ADA) suggests a daily dose of 0.4 units to 1 unit of insulin per kilogram (kg)* of body weight. Half of that amount should be an intermediate or long-acting insulin. The other half should be a rapid-acting insulin, such as NovoLog.
You’ll divide your NovoLog dose throughout the day, taking it 5 to 10 minutes before meals.
For type 2 diabetes, a typical starting dose for NovoLog is 4 units with your largest meal. Your doctor will likely adjust the dose and frequency of NovoLog based on your blood sugar levels.
Be sure to follow the dosage instructions your doctor gives you. They’ll determine the best dosage to fit your needs.
* One kg is equal to about 2.2 pounds.
What’s the dosage of NovoLog for children?
NovoLog is used to manage blood sugar levels in children ages 2 years and older who have type 1 or type 2 diabetes. Your child’s doctor will calculate the dosage of NovoLog for your child based on the type of diabetes they have, as well as their age, weight, and other factors.
The manufacturer of NovoLog doesn’t provide specific dosing recommendations for children. The general insulin dosage guidelines from the ADA for children is the same as for adults, as described in the section just above.
For more information about the right dosage of NovoLog for your child, talk with their doctor.
Is NovoLog used long term?
Yes, NovoLog is usually used as a long-term treatment. If you and your doctor determine that NovoLog is working to manage your blood sugar levels safely, you’ll likely use it long term.
If you have liver or kidney problems, you may have a greater risk of low blood sugar levels. As a result, you may need adjustments to your NovoLog dosage. Tell your doctor about any liver or kidney problems you have. This will help them determine the right NovoLog dosage for you.
Below are answers to some commonly asked questions about NovoLog’s dosage.
What’s a NovoLog sliding scale?
A sliding scale is a chart that provides insulin dosing ranges for each meal. The ranges are based on factors such as a person’s blood sugar levels.
Your doctor may recommend a NovoLog sliding scale. If so, they’ll provide dosing ranges on your sliding scale that account for your diet, how much you exercise, medications you may take, and other factors.
If you have questions about the best way to figure out your dosage, talk with your doctor.
Is the dosage for NovoLog the same as for NovoLog Mix 70/30?
No. Their names may be similar, and they both come in some of the same forms, such as the FlexPen. But your dosage of NovoLog Mix 70/30 would not be the same as your dosage for NovoLog. It’s important to note that these products are different, so they are not interchangeable.
NovoLog is a rapid-acting insulin. You’ll give yourself a dose 5 to 10 minutes before a meal, and its effects typically last 3 to 5 hours.
NovoLog Mix 70/30 is a combination of rapid-acting and intermediate-acting insulin. Usually, you’ll give yourself a dose 15 minutes before a meal. The effects of a dose of NovoLog Mix 70/30 last longer than NovoLog, up to 24 hours.
If you’re prescribed NovoLog Mix 70/30, talk with your doctor about the dosage that’s right for you.
How do I determine my correction dose for NovoLog?
Your doctor will show you how to calculate your NovoLog correction dose. This depends on individual factors.
An insulin correction dose is the amount of extra insulin you’ll need to “correct” a high blood sugar level. You take the extra insulin to help decrease your blood sugar to a certain level (referred to as your target level).
For more information about your NovoLog correction dose, talk with your doctor.
How does NovoLog’s dosage compare with Humalog’s?
NovoLog and Humalog are not interchangeable. But their dosing will be based on similar factors, such as your age, other medications you’re taking, and your blood sugar levels.
Your doctor will recommend the kind of insulin and dosage that’s best suited to manage your blood sugar levels.
To learn more about the similarities and differences between NovoLog and Humalog, see this article.
The dosage of NovoLog you’re prescribed may depend on several factors. These include:

Accessible drug containers and labels
If you find it hard to read the prescription label on your medication, tell your doctor or pharmacist. Some pharmacies may provide medication labels that:
- have large print or use braille
- feature a code that you can scan with a smartphone to change the text to audio
Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t.
You’ll likely give yourself NovoLog around mealtimes. If you miss a dose of NovoLog before eating, you can take your dose during the meal. But if you’ve finished your meal, check your blood sugar level to determine whether you need to take your missed dose. If you aren’t sure, check with your doctor.
Changing your dosing schedule of NovoLog can affect your blood sugar levels. Monitor your blood sugar carefully until your next regularly scheduled dose.
If you’re worried about a missed dose, contact your doctor. They can discuss what to do based on your blood sugar levels.
If you need help remembering to take your dose of NovoLog on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone.

Call your doctor right away if you think you’ve used too much NovoLog. You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource. But if you have severe symptoms, call 911 (or your local emergency number) immediately or go to the nearest emergency room.
The sections above give general information about NovoLog’s dosages. If your doctor recommends NovoLog for you, they’ll prescribe the dosage that’s right for you.
Remember, you should not change your dosage of NovoLog without your doctor’s recommendation. Only use NovoLog exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage.
Here are a few questions you may want to ask them:
- Will my dosage of NovoLog change if I’m using NovoLog FlexPen versus PenFill?
- How does my lifestyle affect my NovoLog dosage?
- Does my NovoLog dosage change if I start taking other medications for my condition?
Will my dosage of NovoLog stay the same or change over time?
Your dosage depends on several factors. These include your blood sugar levels, how you respond to insulin, and any other medications you take. It also depends on lifestyle factors such as how much you exercise and what you eat.
In some cases, your doctor may prescribe a range for your NovoLog dose. The exact amount that you take within the range may vary with each meal based on your blood sugar levels and carbohydrate intake.
In other cases, your doctor may prescribe a set dose of NovoLog for each meal. They may need to adjust the set dose over time depending on how your blood sugar levels respond.
To avoid major shifts in your blood sugar levels, talk with your doctor about your NovoLog dosage. They can let you know whether you need dosage changes.
