How long do you stay on each dose of Wegovy?

Step 1: The 0.25 mg starting dose (weeks 1–4)

Treatment opens at 0.25 mg, a dose whose only job is adjustment. It carries little appetite-suppressing effect in most people, and that is the point. Semaglutide slows gastric emptying, and introducing it gradually means your gut adapts before the therapeutic dose arrives. You stay at 0.25 mg for a minimum of four weeks. If you want to understand what's happening physiologically at this stage, the detail on the 0.25 mg phase covers it fully.

Pen storage is worth sorting from the start: keep each pen in the fridge door rather than the back of the shelf, where temperatures can fluctuate more. Room-temperature limits exist but vary, your Patient Information Leaflet gives the exact window.

A word on what this month isn't: it isn't a test of whether Wegovy is working. Patients sometimes contact us after four weeks at 0.25 mg frustrated that nothing has changed. At this stage, that's entirely expected.

Step 2: Moving through 0.5 mg, 1.0 mg, and 1.7 mg (months 2–5)

Each of these three intermediate doses also carries a four-week minimum. In practice, that means a straightforward titration brings you to the 1.7 mg level around the start of month five. Side effects (nausea, loose stools, fatigue after eating) are most likely to surface in the first week or two after a step-up, then ease as your body adjusts.

If side effects are significant, staying an extra four weeks at a given dose is medically reasonable and is explicitly supported by clinical guidance. There is no clinical benefit to pushing through genuine discomfort quickly; slower titration doesn't blunt the eventual outcome. For a clear breakdown of what each step involves, the overview of all Wegovy doses is a useful reference alongside your prescriber's advice.

The 0.5 mg level is where most people begin to notice a real difference in appetite, meals feel satisfying sooner, and the pull toward snacking between meals tends to quieten. If you're curious about how long you typically spend at the 0.5 mg stage, that question is worth reading up on before your next review, since the answer varies more than people expect.

What you shouldn't do is skip a step or shorten a phase on your own. The titration schedule exists in the licence for good reasons, and the decision to change pace sits with your prescriber and the Wegovy SmPC on the eMC.

Step 3: Reaching and staying on 2.4 mg maintenance

Most people reach 2.4 mg around month five or six, and this is where you stay. There is no further scheduled step-up on the standard Wegovy programme, 2.4 mg is the maintenance dose, and the evidence base (including STEP 1, which reported around 15% average weight reduction at 68 weeks) was built primarily at this level.

How long you remain on maintenance is a separate question from how long you stay on each dose. NICE's recommendation for semaglutide (TA875) notes a maximum of two years within specialist services on the NHS, but this reflects NHS commissioning conditions rather than a biological ceiling; private prescribing is assessed individually and ongoing treatment is reviewed at each clinical check-in. You can read more about the long-term picture on the maintenance dose duration page.

One newer consideration: the MHRA approved a 7.2 mg single-dose Wegovy pen in April 2026, for adults with BMI 30 or above. Trials at this dose reported around 20.7% average weight loss, narrowing the gap with tirzepatide. Whether it's appropriate for you is something to raise at a review, not a self-decision.

What delays or extends your time at a given dose?

Two things most commonly affect the pace. First, tolerability: if nausea, vomiting, or gastrointestinal symptoms are persistent rather than mild and transient, your prescriber will almost always recommend holding your current dose for an extra month rather than stepping up. Rushing a patient through discomfort tends to increase dropout, the exact opposite of the goal.

Second, missing doses. A significant gap in treatment can reset your tolerance, and restarting at a lower dose may be clinically appropriate. How long a gap matters is covered in more detail on the missed dose guidance page, but the short version is: if you've missed more than a couple of weeks, contact your prescriber before your next injection rather than self-managing the restart.

Understanding the dosage amounts across the schedule can also help you track where you are and ask more specific questions at your next review. Titration isn't a one-size-fits-all conveyor belt, it's a clinical process, and the best outcomes tend to belong to patients who stay in close contact with their prescriber rather than managing it in isolation.

If you're weighing up your options or thinking about starting treatment, checking your eligibility with our prescribers is a straightforward first step, free, with no commitment.
