Wegovy Click Calculator UK. FlexTouch Pen Clicks for Every Dose (2026)

Wegovy FlexTouch pens click at 0.01 ml per click, but each strength has a different concentration and a different pen size. There are even two different 0.5 mg pens. This calculator handles every UK presentation, so you can verify doses, plan supply and compare cost per dose.

How Wegovy pen clicks work

Unlike the Mounjaro KwikPen (where every strength delivers 0.6 ml in 60 clicks), Wegovy FlexTouch pens vary in both volume and concentration. The dial clicks in 0.01 ml steps, and what a click "contains" depends entirely on which pen you hold:

PenConcentrationPen sizeDoses per penFull dose is
0.25 mg0.68 mg/ml1.5 ml4 weekly doses≈ 37 clicks (0.37 ml)
0.5 mg (1.5 ml pen)1.34 mg/ml1.5 ml4 weekly doses≈ 37 clicks (0.37 ml)
0.5 mg (3 ml pen)0.68 mg/ml3 ml4 weekly doses≈ 74 clicks (0.74 ml)
1.0 mg1.34 mg/ml3 ml4 weekly doses≈ 75 clicks (0.75 ml)
1.7 mg2.27 mg/ml3 ml4 weekly doses≈ 75 clicks (0.75 ml)
2.4 mg3.2 mg/ml3 ml4 weekly doses≈ 75 clicks (0.75 ml)
Yes, there are two 0.5 mg pens

The 0.5 mg dose comes in two presentations: a 1.5 ml pen at double the concentration, and a 3 ml pen at the same concentration as the 0.25 mg starter. Same 0.5 mg dose, very different click counts (about 37 versus about 74). Pick the right pen in the calculator above, or your numbers will be off by exactly half or double.

A full labelled dose is not a fixed click count on Wegovy. A 0.25 mg dose is roughly 37 clicks of its pen, while a 2.4 mg dose is 75 clicks of the 2.4 mg pen. That is exactly why a calculator beats guesswork. The result also shows the dose in millilitres, so you can sanity-check against the fluid in the window.

Using the calculator to verify, not improvise

The safest use of click knowledge is verification: confirming the pen is working, that fluid moves when you dial, and that you understand what you just injected. The labelled way to take Wegovy is to dial to the dose counter's printed value and inject. No click counting needed.

Where clicks enter the conversation is tapering. If you struggle with side effects on a step-up, some prescribers suggest a temporary lower dose counted in clicks from the same pen. If your prescriber does that, this calculator shows the exact count. If they haven't, don't freestyle it.

The 7.2 mg dose is different

Wegovy 7.2 mg (MHRA-approved January 2026) is supplied as its own pen and, in some cases, has been administered as three 2.4 mg injections under medical supervision. Never assemble a higher dose from multiple pens without explicit prescriber instructions.

Supply and cost per dose

Every Wegovy pen contains exactly four weekly doses at its labelled strength. Enter your actual monthly spend above to see your true cost per dose. The only fair way to compare providers, since headline prices hide consultation and delivery fees. iGovy.co.uk manually verifies UK Wegovy providers before recommending them, including checking that prices shown are the prices actually charged.

Frequently asked questions

How many clicks is a full Wegovy dose? +

It depends on the pen strength, because concentrations differ. A full dose is roughly 37 clicks on the 0.25 mg pen and 75 on both the 1.7 mg and 2.4 mg pens. The calculator above shows the exact figure for every strength. The labelled method is simply to dial to the printed dose value.

How many doses are in a Wegovy pen? +

Four weekly doses at the labelled strength. One pen per 28 days.

Can I count clicks to take a lower Wegovy dose? +

Only if your prescriber has told you to. Clicks scale predictably (0.01 ml per click), which makes prescriber-guided tapering possible, but self-adjusting your dose is off-label and risky.

Do Wegovy pens need the fridge? +

Before first use, yes. Store at 2 to 8°C. Once you are using a pen, it can be kept below 30°C for up to 28 days. Never freeze it, and keep the cap on to protect it from light. Our travel guide covers flying with pens.

What if I miss a Wegovy dose? +

Take it within 5 days if you can. If more than 5 days have passed, skip it and take the next dose on your usual day (never double up).
