Below is information about approved Basaglar dosages for treating type 1 and type 2 diabetes.

Basaglar forms

Basaglar comes as a single-use, prefilled pen called the KwikPen. It also comes as a single-use, prefilled pen called the Tempo Pen. The Tempo Pen is the same as the KwikPen, but you can also connect it to a smartphone app to track your insulin doses.

Both forms of Basaglar are given as a subcutaneous injection.

Basaglar strength

Both the Basaglar KwikPen and Tempo Pen come in one strength: 100 units of insulin glargine per 1 milliliter (ml) of solution. Each single-use pen contains 3 ml of drug solution.

Typical dosages

Your doctor will likely start you with a low dosage of Basaglar. Then they’ll adjust your Basaglar dosage over time to reach the amount that’s right for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Note: Regardless of the condition Basaglar is prescribed to treat, you’ll inject the medication once a day. You may inject Basaglar at any time of day, but you should take your dose at the same time every day.

The maximum dose that either form of Basaglar prefilled pens can deliver is 80 units.

Dosage for type 1 diabetes

The typical starting dosage of Basaglar for treating type 1 diabetes is about one-third of your total daily insulin dosage. (The rest of your total daily dosage should typically be given before or after meals.)

Your total daily insulin dosage is based on your body weight, measured in kilograms (kg). One kg equals about 2.2 pounds (lb). Dosages usually range from 0.4 units/kg to 1 unit/kg per day.

Below is an example of a Basaglar dosing chart for type 1 diabetes:

Your doctor will determine what your specific Basaglar dosage should be. Talk with your doctor about the correct dosage for your condition.

Dosage for type 2 diabetes

For treating type 2 diabetes, the typical starting Basaglar dosage is 0.2 units/kg, up to a maximum starting dosage of 10 units per day. Your doctor will then adjust your dosage based on test results, such as your blood glucose levels.

Talk with your doctor about the dose of Basaglar that’s right for you.

Children’s dosage

Basaglar is approved to improve blood sugar levels in children ages 6 years and older with type 1 diabetes.

The children’s dosage of Basaglar is the same as the dosage for adults. For details, see “Dosage for type 1 diabetes” above.


Basaglar is typically prescribed as a long-term treatment. If you and your doctor determine that Basaglar is safe and effective for you, you’ll likely take it long term.

If you miss a dose of Basaglar, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and take your next dose at the regular time.

You should not take more than one dose of Basaglar within 24 hours, unless your doctor advises you to do so. Taking more than one dose of Basaglar within 24 hours may increase your risk of serious side effects, including hypoglycemia (low blood sugar).

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or timer on your phone or downloading a reminder app. A kitchen timer can work, too.

Below are answers to some frequently asked questions about Basaglar dosages.

Is there a dosing calculator for Basaglar?

The manufacturer of Basaglar doesn’t offer a dosing calculator for you to use.

Your doctor may use a dosing calculator to determine your Basaglar dosage. They may also use one to determine your total daily dose of insulin. These dosing calculators are intended for use by healthcare professionals. If you have questions about how your Basaglar dose was calculated, talk with your doctor or pharmacist.

How do the doses of Basaglar and Lantus compare?

If your doctor is switching you to Basaglar from Lantus, your Basaglar dose will probably be the same as your Lantus dose. This is because they contain the same active drug (insulin glargine) in the same strength: 100 units per milliliter (ml) of solution.

Be sure to take the exact dose your doctor prescribes to you.

If you have additional questions about a dose conversion between Basaglar and Lantus, talk with your doctor or pharmacist.
