Semaglutide at 1 mg/mL: the schedule in units

If the label says 1 mg / 1 mL, 2 mg / 2 mL, 5 mg / 5 mL — it's 1 mg/mL. Read down. Every step of the standard semaglutide ladder, as units on a U-100 insulin syringe.

Semaglutide (Wegovy, Ozempic) titration at 1 mg/mL. Each step is held four weeks before the next.
When	Dose	mL	Units	Syringe
Weeks 1–4	0.25 mg	0.25	25	30-unit
Weeks 5–8	0.5 mg	0.5	50	50-unit
Weeks 9–12	1 mg	1	100	100-unit
Weeks 13–16	1.7 mg	1.7	170 ✗	does not fit in one syringe
Week 17+	2.4 mg	2.4	240 ✗	does not fit in one syringe

Usually labelled 1 mg / 1 mL, 2 mg / 2 mL or 5 mg / 5 mL. Lovely at the start — 0.25 mg is a readable 25 units — and it fails at 1.7 mg, which is 170 units. On Wegovy-style dosing this vial only gets you to 1 mg.

This vial stops at 1 mg. Above that, one dose is more than 100 units — more than one syringe holds. That's two injections per dose, or a stronger vial. Worth raising with the pharmacy at the step before you get there.

Each step on the barrel

0.25 mg → 25 units on a 30-unit syringe

0.5 mg → 50 units on a 50-unit syringe

1 mg → 100 units on a 100-unit syringe

170 units — more than one syringe holds. 1.7 mL: that's two draws, or a stronger vial.

1.7 mg → 170 units

240 units — more than one syringe holds. 2.4 mL: that's two draws, or a stronger vial.

2.4 mg → 240 units

In-between doses at 1 mg/mL

Not on any label. They exist because vials make them possible, and they only make sense if a prescriber put you there deliberately — usually because a full step up was too much at once.

Dose	mL	Units at 1 mg/mL
0.75 mg	0.75	75
1.25 mg	1.25	125 ✗
2 mg	2	200 ✗
