Wegovy Prescription Levels: What the Dose Schedule Actually Means

You've started on 0.25mg and wondered whether that's really doing anything

Almost everyone on Wegovy begins at the lowest level. The first pen isn't there to drive weight loss; its job is to let your gut adapt to semaglutide before the dose climbs. Nausea is the most common reason people stop GLP-1 treatment early, and the slow-start schedule exists specifically to reduce that risk. Four weeks at 0.25mg, four weeks at 0.5mg, and so on, the body generally tolerates the next level better because the previous one has already changed how your stomach empties and how your brain reads hunger signals. If you're feeling impatient at week two, that's understandable. Most people describe the early weeks as anticlimactic. But clinical experience is consistent on this: rushing the schedule trades short-term satisfaction for a much harder time later. Your prescriber sets the pace, and a pharmacist or prescriber can answer specific questions about what your current level should feel like. If you want to understand how a Wegovy prescription works and what the titration process looks like from the start, that page covers what to expect alongside how the medicine works during titration.

The difference between a titration dose and a maintenance dose on the Wegovy schedule

The five main levels split broadly into two groups. Doses up to 1.0mg are stepping stones; 1.7mg and 2.4mg are where most people stay long term, with 2.4mg the standard maintenance dose in clinical trials. In the STEP 1 trial, published in the New England Journal of Medicine, participants on 2.4mg achieved an average body-weight reduction of around 15% over 68 weeks alongside lifestyle changes. In April 2026, the MHRA approved a dedicated single-dose 7.2mg pen (one pre-set weekly injection) for adults with obesity (BMI of 30 or above). Trials at this higher level reported average weight loss of around 20.7% over 72 weeks, approaching results seen with tirzepatide at its highest doses. The 7.2mg level is the maximum; it is reached via the same step-by-step titration from 0.25mg. Jumping directly to a higher maintenance level is not how this medicine works. If you're comparing what different prescription levels might mean for your own situation, the Wegovy cost context page is worth reading alongside this one, prescription level affects how much you'll pay privately each month.

What actually determines which level you're prescribed, and when it changes

Prescribers consider several things when deciding whether to move someone to the next level: how well the current dose is tolerated, what side effects (if any) are present, and whether weight loss is progressing as expected. NICE guidance on semaglutide, published as TA875, notes that if someone has achieved less than 5% weight loss after six months on the maintenance dose, continuing treatment should be reconsidered, which is a useful marker for understanding what the upper levels are meant to deliver. In practice, some people stay at 1.7mg if 2.4mg causes side effects that don't settle. Others move through the schedule faster if tolerance is good. Neither path is wrong. What matters is that a real clinician is reviewing the picture, at nume, every repeat order is looked at by a GPhC-registered prescriber before anything is dispensed, and dose increases require clinical evidence rather than simply being requested. If you're unsure whether your current level is right, the process for getting a Wegovy prescription reviewed explains what that assessment involves.

What changes at each new prescription level, and what to watch for

Each step up typically brings a short recurrence of GI side effects (nausea, loose stools, or a change in appetite) as the body adjusts again. These usually settle within a week or two. The NHS semaglutide page lists the common side effects clearly and is worth bookmarking for reference. More serious symptoms (severe, persistent stomach pain that spreads toward the back, signs of an allergic reaction, or mood changes) need prompt medical attention and should not be attributed to dose adjustment without speaking to a clinician. Yellow Card reporting at yellowcard.mhra.gov.uk is the right route for any suspected serious reaction. The key thing to understand about dose levels is that they are not a ladder to climb as quickly as possible. Each one is a calibrated step, set by regulation and refined by clinical trial data. If you're thinking about starting Wegovy and want to understand how getting a Wegovy prescription online works, or want to know what separates a legitimate route from non-prescription Wegovy sources, speaking to our prescribers is the place to begin.
