Quick answer: can you start Wegovy at 1.7 mg? Not as a new patient, according to the label. Everyone starts Wegovy injection at 0.25 mg once a week and steps up every 4 weeks, reaching 1.7 mg only in weeks 13 to 16.[1] The label also says to restart at a lower dose after 2 or more missed doses in a row. The main exception is switching from the Wegovy pill, where the label does name a 1.7 mg injection.[1]

Here is the schedule, why it exists, and the situations where 1.7 mg comes up. For every product’s schedule, see our semaglutide dosage chart.

The Wegovy titration schedule

The label uses the same step-up for every Wegovy injection indication.[1]

WeeksOnce-weekly dose
1-40.25 mg
5-80.5 mg
9-121 mg
13-161.7 mg
17 onward2.4 mg (recommended) or 1.7 mg

If a dose step isn’t tolerated, the label suggests delaying the next increase by 4 weeks.[1] The schedule is a minimum pace, not a race. Going slower is within the label; going faster is not.

Why you can’t start at 1.7 mg

The label says the step-up exists “to reduce the risk of gastrointestinal adverse reactions”.[1] Even with slow titration, stomach side effects are common. In the trials that support Wegovy 2.4 mg:[1]

Side effectWegovy 2.4 mgPlacebo
Nausea44%16%
Diarrhea30%16%
Vomiting24%6%
Constipation24%11%

Severe stomach side effects occurred in 4.1% of people on Wegovy injection versus 0.9% on placebo.[1] The label also warns that vomiting and diarrhea can cause dehydration, which has led to acute kidney injury, especially during starting and dose increases.[1]

In STEP 1, nausea and diarrhea were typically temporary and mild to moderate, and they eased over time.[3] That pattern is part of why the slow start works: your body adjusts at each level before the next step. Starting at 1.7 mg skips 12 weeks of adjustment.

Trials also show most people can reach the target dose this way. In STEP 4, 89% of participants reached 2.4 mg after the 16-week escalation and 4 weeks of maintenance.[4]

Where 1.7 mg fits as a maintenance dose

1.7 mg is a full approved dose. The label lists it as a maintenance option:[1]

  • Weight reduction in adults: 1.7 mg or 2.4 mg (recommended).
  • Heart risk reduction: 2.4 mg (recommended) or 1.7 mg.
  • Teens aged 12 and older: 2.4 mg (recommended) or 1.7 mg.
  • MASH: 2.4 mg, lowered to 1.7 mg if not tolerated, with the option to try 2.4 mg again.

So some people reach 1.7 mg in week 13 and stay there. That decision is based on how you’re responding and tolerating it. For more on choosing a long-term dose, see our semaglutide maintenance dose guide.

Restarting Wegovy after missed doses

The label has two rules for missed Wegovy injections:[1]

  • One missed dose: if your next scheduled dose is more than 2 days away, take it as soon as possible. If it is less than 2 days away, skip it and take the next one on your usual day.
  • Two or more missed doses in a row: restart the dose escalation at a lower dose to reduce stomach side effects.

The label doesn’t name the exact restart dose. Your prescriber chooses based on how long you’ve been off and how you tolerated the drug before. That might mean going back to 0.25 mg, or to an intermediate step, rather than jumping back in at 1.7 mg or 2.4 mg. Rules for other GLP-1 drugs are in our guide to missed GLP-1 doses.

Switching from Ozempic to Wegovy

Ozempic and Wegovy contain the same drug, semaglutide, but they are approved for different uses and come in different pens and strengths.[1][2]

OzempicWegovy injection
Approved forType 2 diabetes, heart and kidney protection in diabetesWeight reduction, heart risk reduction, MASH
Weekly doses0.25, 0.5, 1, 2 mg0.25, 0.5, 1, 1.7, 2.4, 7.2 mg
Pen typeMulti-dose penSingle-dose pens or syringes; FlexTouch multi-dose pen at 2.4 mg

The Wegovy label doesn’t include a table for switching from Ozempic. It only says Wegovy shouldn’t be used together with other semaglutide products or other GLP-1 drugs.[1] Because the molecule is the same, a prescriber may consider the Ozempic dose you already tolerate when choosing where to start Wegovy. That is a clinical decision, not a label rule. For a broader comparison of GLP-1 doses, see our GLP-1 dose conversion chart and Wegovy vs Ozempic.

When the label does start you at 1.7 mg

The Wegovy label names a 1.7 mg injection in two switching situations, both involving the Wegovy pill:[1]

  1. Couldn’t tolerate the 25 mg pill: switch to Wegovy injection 1.7 mg weekly, starting the day after the last tablet.
  2. Type 2 diabetes and need more weight loss on the 25 mg pill: consider switching to the 1.7 mg injection, then follow the usual step-up.

People moving from the 25 mg pill who tolerate it switch to 2.4 mg instead.[1]

Questions to ask your prescriber

If you’re hoping to move faster or restart at a higher dose, these questions can help:

  1. Given my history, which dose should I start or restart at, and why?
  2. If I tolerated a dose well before, how long can I be off it before I need to step down again?
  3. What should I do if I can’t keep fluids down after a dose increase?
  4. Would staying at 1.7 mg be reasonable for me, or is 2.4 mg the better target?
  5. If I’m switching from Ozempic or the Wegovy pill, how do we time the last old dose and the first new one?

Writing down your doses and side effects at each step makes these conversations easier. A slower path to the maintenance dose still counts as success if it keeps you on treatment.
