Short answer: The Basaglar label gives one injection under the skin once a day, at any time of day but at the same time every day. In type 1 diabetes it starts at about one-third of total daily insulin, with mealtime insulin for the rest. In type 2 diabetes it starts at 0.2 units/kg or up to 10 units once daily. The label has no missed-dose rule.
This is what the FDA label says. Follow your prescriber. Your prescriber may use a different dose or pace than the label's standard schedule.
What Basaglar is approved for: Basaglar is a long-acting insulin approved to improve blood sugar control in adults and children with type 1 diabetes and in adults with type 2 diabetes (section 1). It is not recommended for treating diabetic ketoacidosis.

BASAGLAR (insulin glargine) injection, for subcutaneous use, 100 units/mL, prescribing information, Patient Information and Instructions for Use. Eli Lilly and Company. DailyMed, version published August 10, 2026. DailyMed setid 0ad21db3-2b1c-4ed9-a687-bdd6a74d0aae
Basaglar is injected under the skin of the abdomen, thigh or deltoid (upper arm) once a day at the same time every day, rotating sites within the same region. In type 1 diabetes it is always used with a short-acting insulin. It is not diluted or mixed with any other insulin or solution, and not given into a vein or by insulin pump (sections 2.1 and 2.2).
It comes as U-100 (100 units/mL) in a 3 mL KwikPen or Tempo Pen (300 units), each dialing in 1-unit steps up to 80 units per injection (sections 2.2, 3 and 16.1).

The dose is individualized by metabolic needs, glucose monitoring and glucose goal. Changes may be needed with changes in activity, meals, acute illness or kidney or liver function, and are made only under medical supervision with glucose monitoring.
Glucose is monitored more often during any change to the insulin regimen. The label advises caution for people with poor vision who rely on the pen's clicks.
Basaglar is protected from heat and light and never frozen. An in-use pen is used within 28 days or thrown away, even if insulin is left in it.
The Basaglar label gives no missed-dose rule. Neither the prescribing information nor the Patient Information says what to do if a dose is missed; the label says Basaglar is injected once daily at the same time every day.
More on this: missed a dose of Basaglar.
From another insulin glargine 100 units/mL product, Basaglar starts at the same dose. From once-daily insulin glargine 300 units/mL, it starts at 80% of that dose. From twice-daily NPH, it starts at 80% of the total daily NPH dose. From another intermediate or long-acting insulin, the basal dose may need to change.
Any change of insulin strength, maker, type, site or method is made under close medical supervision with more frequent glucose checks.
In Dose Track you set up Basaglar as a protocol with the dose and schedule your prescriber gave you. A protocol can hold dose steps, each with its own dose and length in days or weeks, so a step-up plan like the one on the label can be entered once and the app moves to the next step on its own. Reminders follow the schedule, and every dose is logged with the date and time, so you can see which step you are on and when your last dose was. The app follows what you enter; it does not choose or change a dose.
