How to inject Saxenda

Taken once daily, at any time of day, without regard to the timing of meals. Everything below is quoted from the FDA label rather than summarised, because a dosing instruction restated twice stops being the label and the detail that goes missing is always the number. What this page adds to the label is the part the label has no reason to carry: what a mistake costs.

How do you inject Saxenda, and what does getting it wrong cost?

Inject SAXENDA subcutaneously in the abdomen, thigh, or upper arm. Rotate injection sites within the same region in order to reduce the risk of cutaneous amyloidosis. Storage is where the money is: the label allows 30 days out of the refrigerator, counted as a total rather than a run, and past it says to discard. At the maintenance rate stored on this site that is $415 thrown away — one pen, one month. And missing doses does more than skip one: if more than 3 days have elapsed since the last saxenda dosage, reinitiate saxenda at 0.6 mg. On a ladder priced per dose, a restart is paid in months at the early rates rather than in a single fill.

What the label says

Where it goes

Inject SAXENDA subcutaneously in the abdomen, thigh, or upper arm.

Rotating sites

Rotate injection sites within the same region in order to reduce the risk of cutaneous amyloidosis.

Before use

Store your new, unused Saxenda pens in the refrigerator at 36°F to 46°F (2°C to 8°C).

Out of the fridge — 30 days

After initial use of the SAXENDA pen, the pen can be stored for 30 days at controlled room temperature 59°F to 86°F (15°C to 30°C) or in a refrigerator 36°F to 46°F (2°C to 8°C).

Freezing

Do not freeze SAXENDA and do not use SAXENDA if it has been frozen.

A missed dose

If a dose is missed, resume the once-daily regimen as prescribed with the next scheduled dose. Do not administer an extra dose or increase the dose to make up for the missed dose.

Missing more than one

If more than 3 days have elapsed since the last SAXENDA dosage, reinitiate SAXENDA at 0.6 mg.

Read from FDA prescribing information for SAXENDA on 2026-08-28. Labels are revised; the date is there so you can tell how old this reading is. Information only, not medical advice — dosing is a decision for the clinician who wrote the prescription.

What a mistake costs

  • A pen left out past 30 days: $415. The label says discard it, and nothing about a partial refund follows — that is a month of medication at the maintenance rate this site stores for Saxenda.
  • A frozen box: the same $415. The label is categorical about not using it, whatever it looks like afterwards.

Injecting Saxenda, answered

Where do you inject Saxenda?
Inject SAXENDA subcutaneously in the abdomen, thigh, or upper arm. Rotate injection sites within the same region in order to reduce the risk of cutaneous amyloidosis. That is the label's wording, not a summary of it. Nothing about the site changes the dose — the label sets no different dose for one site over another.
How long can Saxenda stay out of the fridge?
30 days, and the label states it as a total rather than a run: After initial use of the SAXENDA pen, the pen can be stored for 30 days at controlled room temperature 59°F to 86°F (15°C to 30°C) or in a refrigerator 36°F to 46°F (2°C to 8°C). Past that the instruction is to discard, which is why this page carries a price at all — a discarded pen is $415 of medication at the maintenance rate stored here.
What if you miss a dose of Saxenda?
If a dose is missed, resume the once-daily regimen as prescribed with the next scheduled dose. Do not administer an extra dose or increase the dose to make up for the missed dose. And the part that costs money: If more than 3 days have elapsed since the last SAXENDA dosage, reinitiate SAXENDA at 0.6 mg.
