Semaglutide 1mg in the Context of Wegovy: What You Need to Know

Why does the 1mg step exist in the Wegovy schedule?

Wegovy's titration pathway runs 0.25mg, 0.5mg, 1.0mg, 1.7mg and then 2.4mg, with each dose typically held for around four weeks before the prescriber moves things up. The 1mg level is not arbitrary. The GI side-effect profile of semaglutide (which can include nausea, loose stools, indigestion and fatigue) is most noticeable at the start of treatment or after a dose increase. Spreading the climb across several months allows the body to adjust at each rung before the next one. Most people find that any discomfort at a given dose settles within a week or two, and the 1mg step tends to be where some of that accommodation becomes more established. The clinical trial evidence for semaglutide was built around this graduated approach, which is why the SmPC and prescriber guidance follow it closely. Your prescriber may also choose to stay at 1mg for longer if the previous step was not well tolerated, rather than pushing on. That flexibility is part of good clinical management — the schedule is a guide, not a fixed rule applied without thought.

Who reaches the 1mg dose, and is everyone eligible for Wegovy at all?

Wegovy is licensed in the UK for adults with a BMI of 30 or above, or a BMI of 27 to 29.9 alongside at least one weight-related condition such as high blood pressure, type 2 diabetes, or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. Reaching the 1mg dose simply means you have already spent time at 0.25mg and 0.5mg, so it is a marker of progress through treatment rather than a starting point. It is worth noting that Wegovy is not recommended during pregnancy, while breastfeeding, or when actively trying to conceive, and it is not licensed for anyone under 18. People with a personal or family history of certain thyroid conditions or a history of pancreatitis would have those factors reviewed carefully before treatment started. NICE's recommendation for semaglutide (TA875) sets out the population eligible for NHS access; private treatment through a regulated pharmacy operates to the licensed criteria rather than NICE's NHS-commissioning thresholds. For a straightforward comparison of the two access routes, the Wegovy treatment page explains both clearly.

What does day-to-day life look like at the 1mg strength?

The injection itself is a small, pre-filled pen used once a week. At the 1mg step you are using the same injection technique as at any other dose, a short needle, typically into the abdomen, thigh, or upper arm, rotated across sites. The pen is stored in the fridge at home, though it can be kept at room temperature for a limited window when you are travelling; the exact duration is in the Patient Information Leaflet, and your prescriber is the right person to check that detail with rather than relying on a general source. When your first supply arrives from our pharmacy it comes in plain, unbranded packaging via DPD, with tracking sent to your phone, nothing on the outside identifies what is inside. Side effects at this stage are still largely GI in character: nausea, changes to bowel habit, and sometimes a low appetite that can make adequate protein and fluid intake harder to maintain. Those points are worth raising at your next clinical check-in. The next dose step (1.7mg) is typically where people begin to approach the maintenance phase, though the 2.4mg strength remains the standard endpoint. You can also read about what the data shows at higher dose levels for broader context on how results accumulate over treatment.

How does the cost picture look as the dose increases?

Each pen in the Wegovy range covers four weekly injections, so the cost of treatment shifts as you move up the schedule. The 1mg strength is not the most expensive point (that comes later) but it is worth understanding the total picture before you commit to treatment. Eli Lilly's widely reported list-price increase for Mounjaro in August 2025 prompted similar market attention on Wegovy pricing; typical private costs in the UK vary by dose and provider. Our Wegovy price comparison page sets out what those figures actually look like and what a transparent private prescription includes. At nume, one price covers the consultation, the prescription, the medicine, and free next-working-day delivery, no subscription, no auto-renewal, and no hidden charges. A named GPhC-registered Independent Prescriber reviews every order the same day it is submitted. For anyone considering the oral alternative, the oral semaglutide page covers the MHRA-approved Wegovy tablet that launched in June 2026. If you have questions that are not answered here, the FAQs page covers the most common ones our prescribers hear.
