GLP-1 pen click charts
What a "click table" really means, the click-to-milligram math for each dial-a-dose pen, and the pens that have no clicks at all.
A GLP-1 pen click table converts the audible clicks of a dial-a-dose injection pen into an estimated milligram amount: milligrams per click equal the pen's contents divided by its total clicks of dial travel. It only applies to pens with a turnable dose dial. For Ozempic, community tables most often cite roughly 37 dose-dial clicks for the full labeled dose on every pen — so the same ~37 clicks deliver 0.5 mg on the 0.25/0.5 mg pen, 1 mg on the 1 mg pen, or 2 mg on the 2 mg pen (a separate "72–74 clicks = 1 mg" convention also circulates). Mounjaro/Zepbound multi-dose KwikPens are documented at 60 clicks per full dose. Wegovy has no clicks — it is a fixed single-dose pen.
Estimate — verify with your pharmacist. Based on the community-cited full-dose click count for the selected pen. Your pen may differ; confirm the count and read the dose counter before injecting.
Mechanics differ by region and pen format. The converter covers dial-a-dose pens only; single-dose Wegovy and US single-dose tirzepatide pens have no clicks to convert.
Ozempic (semaglutide) pens
Ozempic ships in three multi-dose, dial-a-dose pens. All three are turned by a dose selector that clicks as it moves. The dominant community model counts the dial to the pen's single labeled stop — roughly 37 clicks for a full dose on every pen — so milligrams per click scale with the pen's strength.
| Pen (label color) | Total contents | Labeled dose(s) | ~Clicks to full dose | Est. mg / click |
|---|---|---|---|---|
| 0.25 / 0.5 mg (red) | 2 mg / 1.5 mL | 0.25 & 0.5 mg | ~18–19 (0.25 mg) · ~37 (0.5 mg) | ~0.0135 mg |
| 1 mg (blue) | 4 mg / 3 mL | 1 mg | ~37 | ~0.027 mg |
| 2 mg (gold) | 8 mg / 3 mL | 2 mg | ~37 | ~0.054 mg |
Caveat: the red 0.25/0.5 mg pen is built to stop at 0.5 mg; dialing "past" a pen's labeled maximum is not a supported motion and click feel changes near the end of travel.
Mounjaro & Zepbound (tirzepatide)
Tirzepatide is where pen format matters most, because it differs by market. The multi-dose KwikPen (standard in the UK/EU, also sold in the US alongside single-dose forms) is a dial-a-dose pen holding four weekly doses, widely documented at 60 clicks of dial travel per full labeled dose across every strength. The US single-dose autoinjector pens and single-dose vials have no dial and no clicks — one fixed dose, then discard.
| KwikPen strength | Labeled dose | ~Clicks to full dose | Est. mg / click | ~Half-dose (30 clicks) |
|---|---|---|---|---|
| 2.5 mg | 2.5 mg | ~60 | ~0.042 mg | ~1.25 mg |
| 5 mg | 5 mg | ~60 | ~0.083 mg | ~2.5 mg |
| 7.5 mg | 7.5 mg | ~60 | ~0.125 mg | ~3.75 mg |
| 10 mg | 10 mg | ~60 | ~0.167 mg | ~5 mg |
| 12.5 mg | 12.5 mg | ~60 | ~0.208 mg | ~6.25 mg |
| 15 mg | 15 mg | ~60 | ~0.25 mg | ~7.5 mg |
Caveat: confirm you have the multi-dose KwikPen, not a single-dose pen or vial. The KwikPen dose counter shows mg — use it, not a memorized click count. Microdosing tirzepatide by counting clicks is off-label and not manufacturer-recommended.
Wegovy (semaglutide) — no clicks to count
If you searched for a "Wegovy click table," here is the honest answer: the current Wegovy pen has no dose dial and no clicks to count. It is a single-dose, fixed-dose autoinjector — the factory presets each pen to one weekly dose (0.25, 0.5, 1.0, 1.7, or 2.4 mg) and you use the whole pen, then discard it.
The two clicks you hear during a Wegovy injection are simply start and finish cues — the first confirms the injection began, the second confirms the dose finished. They are not dose increments and cannot be counted to make a smaller dose.
The "Wegovy click table" search intent is, for the most part, misdirected — people are usually looking for the Ozempic (same drug, dial-a-dose pen) or Mounjaro mechanics instead. A small number of older multi-dose Wegovy pens with a dial existed, but the current US-market pen is single-dose.
Saxenda & Victoza (liraglutide) pens
Liraglutide pens are dial-a-dose multi-dose pens — Saxenda (18 mg / 3 mL) delivers 0.6 / 1.2 / 1.8 / 2.4 / 3.0 mg, and Victoza (18 mg / 3 mL) delivers 0.6 / 1.2 / 1.8 mg. The dial clicks as it turns.
But the manufacturer guidance here is unusually explicit: do not count clicks. The patient leaflet states the dose selector clicks differently when turned forward, backward, or past the mg remaining, which makes click counting unreliable — and instructs you to use only the numeric dose counter and dose pointer to confirm mg before injecting. For that reason we publish no liraglutide click-to-mg figures.
These are daily injections (unlike the weekly pens above), so a miscount compounds quickly. Read the dose counter every time.
Why people count clicks
Two motivations come up most in search. We describe them neutrally; OptiPin does not endorse either, and both are off-label uses of a pen designed for fixed doses.
- Titrating between the labeled steps. The standard escalation jumps in large increments. Some people look for an in-between dose — a step the pen doesn't have a labeled stop for — usually to ease gastrointestinal side effects. This is a prescriber decision, not a do-it-yourself one.
- Stretching supply. A higher-strength pen holds more drug than one labeled dose; counting clicks is how people try to spread it across more weeks to manage cost. The trade-off is dosing accuracy, needle reuse, and using a pen past its in-use limit — all of which carry real risk.
Drug-safety bodies (including ISMP) have documented miscount errors from these practices — hard-to-hear clicks, dose mismatches between home and clinic, and pens used beyond their dating. If your protocol involves anything other than the pen's labeled dose, get it in writing from your prescriber and tell your pharmacist.
How the click-to-mg math works
Every figure on this page comes from one transparent idea:
estimated dose = clicks counted × mg per click
Example: a tirzepatide KwikPen delivers a 5 mg labeled dose in about 60 clicks, so each click is roughly 5 ÷ 60 ≈ 0.083 mg, and 30 clicks ≈ 2.5 mg. The arithmetic is simple; the uncertainty is in the inputs. "Clicks to full dose" is a community-observed number that varies by how you count, and a pen's mechanical delivery has tolerance. That is why every output above is an estimate, flagged to verify against your own pen and pharmacist.

FAQ
What is a GLP-1 pen click table?
A community-made chart that converts a dial-a-dose pen's audible clicks into an estimated mg amount. Milligrams per click equal the pen's contents divided by total clicks of dial travel. It only applies to pens with a turnable dial, and it isn't a manufacturer-endorsed dosing method.
How many clicks are in an Ozempic pen?
Most tables cite ~37 dose-dial clicks for the full labeled dose on any Ozempic pen, so the same ~37 clicks give 0.5 mg, 1 mg, or 2 mg depending on the pen. A finer "72–74 clicks = 1 mg" convention also circulates. They disagree because people count the dial differently — verify on your own pen.
Does Wegovy have a click table?
No. The current Wegovy pen is a fixed single-dose autoinjector with no dial and no countable clicks. The two clicks you hear are start and finish cues. Searches for a "Wegovy click table" usually want the Ozempic or Mounjaro mechanics.
How many clicks are in a Mounjaro or Zepbound KwikPen?
The multi-dose tirzepatide KwikPen is widely documented at ~60 clicks of dial travel per full labeled dose, on every strength (2.5–15 mg), so mg per click scales with the pen. US single-dose autoinjector pens and single-dose vials have no dial and no clicks.
Is counting clicks to take a partial dose safe?
GLP-1 pens are designed to deliver fixed approved doses. Counting clicks for a smaller or in-between dose is off-label and not manufacturer-validated — Novo Nordisk explicitly does not recommend it. Real delivered amount can drift from the count, and miscounts are easy. Any dose change is a prescriber decision; confirm mechanics with your pharmacist.
Why do people count clicks on a GLP-1 pen?
Mostly two reasons: titrating to an in-between dose to manage side effects, and stretching a higher-strength pen across more weeks. Both are off-label. This page documents the math people search for; it doesn't endorse either. Discuss changes with your prescriber and pharmacist.
How do I calculate milligrams per click?
Milligrams per click = pen's deliverable contents ÷ clicks to the maximum labeled dose. If a pen delivers a 5 mg dose in 60 clicks, that's ~0.083 mg per click, and 30 clicks ≈ 2.5 mg. Treat every result as an estimate and verify the count on your specific pen.
