How Often Should You Increase Your Wegovy Dose — and What Guides the Timing?

Step 1: The 0.25 mg starting dose and why four weeks matters

Treatment begins at 0.25 mg once a week. That might feel like a small amount, and it is, deliberately. The starting dose isn't chosen for weight-loss effect; its job is to let your system settle into the medicine before anything stronger is introduced. Nausea, the most common early complaint, is considerably less likely when the body has time to adapt gradually.

Most people use two or three pens at 0.25 mg before their prescriber confirms they're ready to move up. Four weeks is the minimum interval the licensed titration schedule sets between steps, and it applies at every rung of the ladder, not just the first. Rushing that interval doesn't produce faster weight loss, it mainly produces more side effects. The full Wegovy dose schedule sets out each step and what to expect from it.

During this opening month, keeping notes on how you're feeling (appetite changes, any nausea, sleep) gives your prescriber useful material at review. The NHS patient information for semaglutide covers what to watch for at each stage, and it's worth reading before you start.

Step 2: Moving through 0.5 mg, 1.0 mg and 1.7 mg (the middle rungs

After the initial four weeks at 0.25 mg, the schedule moves to 0.5 mg, then 1.0 mg, then 1.7 mg) each held for approximately four weeks. So from the very first injection to reaching the 2.4 mg maintenance dose, the minimum timeline under the standard schedule is around five months. That is not a slow route; it's the route the clinical trials followed when producing the weight-loss results that led to UK licensing.

A question our prescribers hear fairly regularly is whether it's safe to stay longer at a dose that feels comfortable rather than pushing to the next level. The answer is yes, in many cases. If you're losing weight steadily and tolerating the current dose well, there is no clinical obligation to increase. The schedule sets minimums, not deadlines. When to move up your Wegovy dose explores the clinical signals that prompt that conversation.

Side effects tend to peak shortly after a dose increase and ease over the following one to two weeks for most people. If they haven't settled within that window, contact your prescriber rather than waiting for your next scheduled review.

Step 3: Reaching 2.4 mg maintenance, and the 7.2 mg pathway

For most people, 2.4 mg once weekly is the maintenance target. The STEP 1 trial, published in the New England Journal of Medicine, found an average body-weight reduction of around 15 per cent over 68 weeks at this dose, alongside reduced-calorie eating and increased activity, a result that informed the NICE recommendation for semaglutide.

In January 2026 the MHRA approved a higher 7.2 mg dose, and in April 2026 a dedicated single-dose 7.2 mg pen was confirmed for adults with a BMI of 30 or above. Trials at this higher dose reported average weight loss of around 20.7 per cent over 72 weeks. The titration still starts at 0.25 mg; 7.2 mg is the ceiling, reached by the same step-wise process. Whether the higher dose is appropriate for you is a clinical decision your prescriber makes based on your response and tolerability at 2.4 mg. Specific dose availability is confirmed at consultation, how to access Wegovy through a regulated UK pharmacy explains the practical steps.

What can slow or pause a dose increase?

Not every increase goes smoothly to plan, and that's normal. The most common reason a prescriber holds a dose steady is persistent gastrointestinal symptoms, nausea that hasn't eased, significant vomiting, or diarrhoea that's affecting daily life. Pushing through those symptoms by increasing the dose rarely helps; staying put for another four weeks (or longer) usually does.

There are also clinical reasons that may prompt a pause: a period of illness, a surgical procedure coming up, or a medication change that needs reviewing first. How much Wegovy to take covers the factors that shape the right dose for each person in more detail. It's also worth knowing that the NHS England guidance on weight-management injections sets out the clinical framework prescribers follow, including when continuing at a dose may be the right call rather than titrating upward.

If cost context is part of your thinking as you plan treatment, our treatment page shows what's included at each stage, one transparent price covering consultation, prescription and delivery, with clinical review at every repeat. No subscription, no automatic renewals.

Dose decisions belong to your prescriber, and at nume a real clinician reads every consultation the same day. If you have questions about where you are in the schedule or whether a dose change makes sense for you, many people also find it helpful to read about how Wegovy can increase energy levels as part of understanding what to expect at each stage, before speaking with our clinical team rather than relying on a dose chart alone.
