Wegovy clicks dosage chart: reading your pen and choosing the right dose

Why the Wegovy pen uses clicks, and what they actually tell you

The click mechanism is a delivery confirmation system, not a counting exercise. When you press and hold the injection button on a Wegovy pen, a series of clicks is produced as the plunger drives the medicine through the needle. The final click signals that the mechanism has completed its travel and the full dose has been expelled. Hold the pen in place for at least six seconds after that last click before withdrawing, releasing too early risks leaving a small volume of medicine at the injection site rather than under your skin.

The click count differs between pen strengths. A 0.25 mg pen and a 2.4 mg pen do not produce the same number of clicks, because the plunger travels a different distance. This is why the click dosage chart is pen-specific: the number printed in your Patient Information Leaflet (which is the authoritative source) is the one that applies to your prescribed strength. The broader Wegovy clicks and dosage guidance covers this pen-by-pen breakdown in detail.

One thing worth knowing: if you hear no clicks at all, or fewer than expected, do not inject again without speaking to your prescriber or pharmacist. An incomplete injection is not the same as a missed dose, and the two are managed differently. The NHS medicines page for semaglutide covers what to do if something goes wrong with your injection.

Reading the chart alongside the titration schedule

The titration schedule (the step-by-step dose increase) is where the clicks dosage chart becomes genuinely useful. Wegovy starts at 0.25 mg for the first four weeks. That is not a therapeutic dose; it is a period of adjustment, giving your body time to settle into the medicine before the dose rises. From there, each step increases roughly every four weeks: 0.5 mg, then 1.0 mg, then 1.7 mg, before reaching the 2.4 mg maintenance dose.

Each of those steps involves switching to a new pen strength, and with a new pen comes a new click count. The full guide to Wegovy doses explains what each stage involves practically, including what to expect as the dose changes. For the 1 mg pen specifically, the 1 mg pen clicks chart provides targeted detail.

A note on timing: if you are planning ahead around a bank holiday, a holiday abroad, or you are waiting on a prescription renewal, ordering by the Monday before payday gives you the most reliable window. Wegovy pens need refrigeration between 2°C and 8°C, and the Patient Information Leaflet specifies the maximum time out of the fridge during use, always check that document for the exact figures rather than relying on memory.

For the higher 2.4 mg maintenance dose and the newer 7.2 mg pen option, the 2.4 mg clicks chart provides specific guidance. Your prescriber will advise on whether a higher maintenance dose is appropriate for you.

The decision the chart cannot make for you

A clicks dosage chart tells you how to complete an injection correctly. It does not tell you which dose you should be on, when to escalate, or whether to stay at a lower dose longer because of side effects. Those are clinical decisions. Some people move through the titration steps exactly as scheduled; others slow down at 1.0 mg or 1.7 mg because nausea or other gastrointestinal effects need more time to settle. That is not a failure, it is the schedule working as intended.

Side effects across the titration are predominantly gastrointestinal: nausea, loose stools, constipation, indigestion, and fatigue are the most commonly reported, and they tend to be most noticeable in the days after a dose increase before easing. The relevant section of the NICE appraisal of semaglutide (TA875) places these within the broader clinical picture of who benefits and under what conditions. If you experience severe stomach pain that spreads to your back, stop the injection and seek medical attention promptly, this pattern warrants urgent assessment.

If you are weighing up the private cost of treatment while you work through the click chart, the Wegovy UK cost guide explains what drives pricing differences and what a legitimate prescription service includes. The full Wegovy overview is a good place to read about the medicine more broadly before your next clinical review.

Getting the technique right every time

The clicks are only part of good injection technique. Rotating your injection site (between the abdomen, the outer thigh and the upper arm) reduces the chance of skin reactions building up in one spot. A fresh needle for each injection is standard practice; reusing needles blunts the tip and can affect how reliably the pen delivers. Swabbing the chosen site with an alcohol swab before injecting and letting it dry fully takes seconds and removes surface bacteria.

Press the pen firmly against the skin, press the injection button slowly and steadily, listen for the clicks to complete, then hold for the full six seconds before removing the pen. Dispose of the used pen in a suitable sharps container, never in household waste. If any of this feels uncertain, your pharmacist or prescriber is the right person to ask. Our frequently asked questions cover common injection technique questions, and our team is available seven days a week through our contact page if you need to speak to someone before your next dose.

If you are ready to start treatment or discuss which dose is right for your situation, speak to our prescribers, a real clinician, not a queue-routing system, reads every consultation the same day it arrives.
