Semaglutide dosing schedule (Wegovy and Ozempic)

Wegovy and Ozempic both go 0.25 mg for weeks 1–4, then 0.5 mg for weeks 5–8. After that they split: Wegovy steps to 1 mg, 1.7 mg and 2.4 mg every 4 weeks, while Ozempic may go to 1 mg and then 2 mg. Pick your medicine, add the date of your first injection and download or print a week-by-week log.

The early steps are there to let the stomach adjust; the label treats them as escalation doses, not maintenance doses. The chart above runs to week 24 at 2.4 mg for Wegovy and doesn't include the 7.2 mg option.

Download or print the log

  • Choose Wegovy or Ozempic and, if you like, the date of your first injection. Every week gets its date.
  • Choose Download PDF to save the log and graph, or Print for a paper copy. The log is page 1 and the graph is page 2; weekly dates are included if you entered a start date.
  • Write the dose you actually took. If your prescriber holds a dose longer, it will differ from the label column, and that's expected.
The label schedule isn't a personal plan. Only your prescriber can decide when to increase, hold or lower a dose. If you use a pen, inject only the doses printed on its dial; see the pen instructions page for why click counts do not establish a dose.
Correction — November 9, 2026. The simplified “amount in the body” estimate was removed. The chart now shows an illustrative label-dose path only; the log records the dose actually taken separately.

Questions

What is the Wegovy dose schedule?

Per the label: 0.25 mg once a week for weeks 1–4, 0.5 mg for weeks 5–8, 1 mg for weeks 9–12 and 1.7 mg for weeks 13–16. From week 17 the maintenance dose for weight reduction is 2.4 mg or 1.7 mg once a week. The label also allows 7.2 mg for people who have taken 2.4 mg for at least 4 weeks, when the prescriber decides more weight reduction is needed.

How is the Ozempic schedule different?

Ozempic is labeled for type 2 diabetes. It goes 0.25 mg for 4 weeks, then 0.5 mg. After at least 4 weeks at 0.5 mg the dose may go to 1 mg, and after at least 4 more weeks to 2 mg, the maximum. Those last two steps happen only if more blood sugar control is needed.

Can the dose go up more slowly than this?

Yes. The weeks shown are the earliest the label allows. Prescribers often hold a dose longer if side effects such as nausea haven't settled. Follow the dose and timing your prescriber gives you.

What if I miss a dose?

The labels give specific rules for missed doses, and they differ between Wegovy and Ozempic. Check the medication guide that came with your pen or ask your pharmacist.

I use compounded semaglutide from a vial. Does this apply?

The doses in mg can follow the same steps if your prescriber says so, but you measure them in units on a syringe. Use the peptide calculator to turn each mg dose into units for your vial's concentration.
