Reading the wegovy clicks dosage chart for the 1mg pen

You're holding the 1mg pen, here is what you are actually hearing

Picture this: you have pressed the injection button against your skin, you hear the first click as the injection starts, and then a second click a few seconds later. That second click is the signal the full dose has gone in. You hold the pen in place for six seconds after that second click before withdrawing, to make sure none of the medicine tracks back out. The Wegovy pen is designed so that the mechanism confirms completion for you, there is no measuring, no manual drawing-up. The dose is pre-set at the factory.

What makes this occasionally confusing is that people sometimes hear the first click and pull the pen away. That is not a complete injection. The NHS patient information for semaglutide is clear that the second click is the reliable end signal, and the six-second hold afterwards is part of the correct technique. If you are uncertain whether you caught the full dose, do not attempt a second injection, check the Patient Information Leaflet or speak to your pharmacist. The NHS medicines page for semaglutide has a step-by-step technique guide worth bookmarking.

The 1mg pen itself is a distinct device from the 0.5mg and 1.7mg pens. They are not interchangeable, and the click mechanism is calibrated to the specific volume of medicine in that pen. Each is a single-patient, single-use cartridge format: once the pen is finished, it goes in a sharps container, not the general bin. If you want to understand exactly how many clicks correspond to each dose, our Wegovy clicks dosage chart breaks this down clearly for each pen in the titration sequence.

Where the 1mg dose sits on the full Wegovy titration chart

Wegovy's licensed titration pathway runs in roughly four-week steps: 0.25mg, then 0.5mg, then 1mg, then 1.7mg, reaching 2.4mg as the standard maintenance dose. The 1mg step is the midpoint, your system has already had at least eight weeks on lower doses by the time you reach it. If you want the full picture of how each step connects, the Wegovy dosage chart maps the whole pathway.

The purpose of each step is tolerability, not a partial treatment effect. Nausea, indigestion and loose stools are more likely when the dose goes up, and the gradual steps give your body time to adjust before the next increase. Reaching 1mg is normal progress; it does not mean you are partway through a failed treatment. Most people find GI symptoms, if they appear, are worst in the first week of a new dose and settle before the next step is due.

Clinicians can hold a dose for longer than four weeks if side effects need more time to settle. The schedule in the chart is a guide, not a timetable you must stick to regardless of how you feel. If you would like a detailed explanation of how the 1mg dose is administered and what to expect from it, our page on Wegovy clicks dosage covers the mechanics of each injection step. For context on cost as doses increase, the Wegovy pricing page explains how treatment costs vary across the titration stages.

Storing the 1mg pen correctly, and a few things people miss

Wegovy pens are kept in the fridge between 2°C and 8°C. Tuck it somewhere stable in the fridge door rather than the back of a shelf where it risks freezing if the temperature fluctuates. Once you have taken your weekly dose, the used pen should go straight into a sharps container. If the pen has been out of the fridge (for travel or a day out) there is a limited room-temperature window before it should be discarded. The exact window is in the Patient Information Leaflet; always check there rather than relying on a secondhand figure, because advice can be updated and the leaflet is the authoritative source. The eMC (electronic Medicines Compendium) holds the full Wegovy SmPC, including storage conditions, which is worth reading before your first pen.

One thing people regularly miss: Wegovy pens must not be frozen. If a pen has accidentally been frozen (pushed to the very back of the fridge, or left near the freezer compartment) it should not be used. Contact your pharmacist if you are unsure whether your pen has been stored correctly.

Injection sites for Wegovy are the abdomen, the outer thigh, and the upper arm. Rotate the site each week. Some people find keeping a simple note on their phone of which site they used last makes rotation easier without having to remember it.

What a clicks chart cannot tell you, and when to get medical help

A dosage chart tells you the intended schedule and helps you follow injection technique. It cannot tell you whether Wegovy is right for you personally, whether to stay on 1mg longer, or whether a symptom you are experiencing is a normal adjustment effect or something that needs attention. Those are clinical judgements. For a thorough overview of Wegovy treatment, the Wegovy treatment guide covers the full clinical picture, and the doses page goes into each step in more detail.

Seek urgent medical help if you develop severe stomach pain that is persistent and may radiate to the back, with or without vomiting, this can be a sign of pancreatitis, which the MHRA flagged in a Drug Safety Update for GLP-1 medicines in January 2026. Other symptoms that need prompt attention include signs of a serious allergic reaction (swelling of the face or throat, difficulty breathing), gallbladder pain, or symptoms of dehydration from severe vomiting or diarrhoea. Do not wait for your next scheduled check-in if something feels wrong. You can also report any suspected side effects via the MHRA Yellow Card scheme, which helps regulators track safety signals across the population.
