Saxenda dosing — and the liraglutide calculator

Saxenda is the weight-management brand of liraglutide, supplied as a multi-dose prefilled pen with a dose dial. Unlike the weekly GLP-1 brands, Saxenda is dosed once daily. This page explains the Saxenda dose schedule, then gives you the calculator you need if you are dosing a compounded liraglutide vial instead.

The Saxenda daily dose schedule

Saxenda is taken once a day, and the pen dials the labelled dose, so there is nothing to measure. The label's titration starts low and steps up about once a week until the maintenance dose is reached — a faster cadence than the weekly GLP-1 products because dosing is daily.

Because the pen meters the dose, you never reconstitute or draw a Saxenda pen. The math only appears with a compounded liraglutide vial.

  • Once-daily dosing (not weekly)
  • Typical steps: 0.6 → 1.2 → 1.8 → 2.4 → 3.0 mg per day
  • Pen dials the dose — no reconstitution or unit math

Saxenda pens vs compounded liraglutide vials

A compounded liraglutide vial is reconstituted and drawn by hand, unlike a Saxenda pen. With daily dosing, a vial is used across many days, so the reconstitution date and beyond-use date matter — and you convert each daily dose into a draw volume and syringe units yourself.

On Saxenda pens you do not need the calculator. On a compounded vial dosed to a comparable daily schedule, the liraglutide calculator below turns each step into the units to draw.

  • Pen = dialled daily dose, no math
  • Compounded vial = you calculate the daily draw and units
  • Track the beyond-use date — one vial spans many days

Frequently asked questions

Do I need a calculator for Saxenda?+
Not for Saxenda prefilled pens — the pen dials the daily dose. You only need a calculator for a compounded liraglutide vial, where you convert vial mg and BAC water into a draw volume and syringe units.
What are the Saxenda dose steps?+
The label's daily titration is 0.6, 1.2, 1.8, 2.4, then 3.0 mg, usually stepping up about once a week. This is general information, not a recommendation — follow your prescriber's plan.
Why is Saxenda daily when Ozempic and Wegovy are weekly?+
Saxenda uses liraglutide, which has a shorter half-life (~13 hours) than semaglutide, so it is dosed once daily. The weekly brands use longer-acting compounds. The reconstitution math is the same; only the schedule differs.
