Wegovy is a once-weekly injectable medication containing semaglutide, approved for chronic weight management in adults with obesity or overweight plus weight-related health conditions. It comes in a pre-filled, multi-dose pen with a dial that clicks to select the dose. The pen delivers fixed amounts measured in milligrams (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg), but the number of clicks required to reach each dose is not printed on the pen itself.
Many users need to know exactly how many clicks correspond to each prescribed dose, especially if the pen is used off-label, if they are splitting doses, or if they are transitioning between strengths. The click count is the same across all Wegovy pens regardless of the labeled strength because the mechanical design is standardized. Understanding the click-to-dose relationship prevents under-dosing or accidental overdosing.
This article explains the official click counts for every Wegovy dose, how the pen mechanism works, why accurate counting matters, and practical tips for safe administration. The information is for educational purposes only and not medical advice. Never adjust your dose or injection technique without explicit instructions from your prescribing healthcare provider.
How the Wegovy Pen Delivers Doses
Each Wegovy pen contains 4 full doses of the labeled strength. The dose selector dial turns in fixed increments—each “click” corresponds to a very small volume of liquid. The pen is engineered so that the number of clicks required to reach the intended milligram dose is consistent across all strengths.
When you turn the dial, you hear and feel distinct clicks. The pen does not display the number of clicks or the milligram dose while you are dialing—it only shows the final selected dose in mg once you reach the correct stopping point. For this reason, many patients count clicks manually during training or when confirming the dose.
The click count is the same for every pen because the internal gearing and volume per click are identical. The difference between pens is the concentration of semaglutide per milliliter, not the mechanical click mechanism.
Why Click Counting Is Sometimes Necessary
- To verify the pen is delivering the correct dose during training
- To double-check the dose before injecting if the dial markings are unclear
- To split a higher-strength pen into smaller doses (off-label, provider-supervised only)
- To troubleshoot if the pen seems to deliver less than expected
Click counting is a safety double-check, not a replacement for reading the labeled dose.
Official Wegovy Click Counts by Dose
The Wegovy pen has a standardized click count for each dose strength. These numbers come directly from the manufacturer’s training materials and device instructions. The counts are the same regardless of which strength pen you are using.
Here are the exact click counts for each labeled dose:
- 0.25 mg = 18 clicks
- 0.5 mg = 36 clicks
- 1 mg = 72 clicks
- 1.7 mg = 108 clicks (1.7 mg pen only)
- 2.4 mg = 72 clicks (2.4 mg pen only)
Important note: the 1.7 mg and 2.4 mg doses both require 72 clicks on their respective pens because the concentration is adjusted so the same number of clicks delivers the higher milligram amount. Never use click counts from one strength pen on a different strength pen.
Quick Reference Click Chart
- 0.25 mg → 18 clicks
- 0.5 mg → 36 clicks
- 1 mg → 72 clicks
- 1.7 mg → 108 clicks (1.7 mg pen)
- 2.4 mg → 72 clicks (2.4 mg pen)
Memorize or keep a printed copy of this list until you are comfortable with the pen.
How to Count Clicks Correctly
Hold the pen with the dose selector facing you. Turn the dial slowly in the direction of the arrows (usually clockwise). Count each distinct “click” sound and tactile stop as one click. Do not count the initial click when you start turning from zero.
Stop exactly at the prescribed number of clicks. Do not go past and then dial back—back-dialing can cause inaccurate delivery. If you overshoot, dial past the maximum dose until the pen stops, then start over from zero.
After reaching the correct number of clicks, the dose window should display the exact mg amount (0.25, 0.5, 1.0, 1.7, or 2.4). If the window does not match the expected mg for your pen strength, do not inject—contact your pharmacist or provider.
Safe Click-Counting Steps
- Turn the dial slowly and count each click
- Stop exactly at the correct number
- Confirm the dose window shows the prescribed mg
- If anything feels wrong, dial back to zero and start over
- Never force the dial past its stopping point
Accurate counting prevents dosing errors.
Common Mistakes When Counting Clicks
The most frequent error is counting the starting position as click #1. The first turn away from zero is click #1; do not count the zero position itself.
Another common mistake is dialing backward to correct an overshoot. Back-dialing can cause the pen to deliver an inaccurate dose. Always dial past the maximum and start over from zero if you go too far.
Some users count too quickly and miss clicks or double-count. Turn slowly and deliberately, using one finger to feel each stop. Practicing with an empty training pen (if available) helps build confidence.
Mistakes to Avoid
- Counting the zero position as a click
- Dialing backward to correct an overshoot
- Turning the dial too quickly and missing clicks
- Assuming the click count is different for each pen strength
- Forcing the dial past its natural stopping point
Double-checking the dose window after counting eliminates most errors.
Why Accurate Dosing Matters
Semaglutide is a potent medication. Receiving too little reduces effectiveness and may slow weight loss or blood sugar control. Receiving too much can intensify nausea, vomiting, diarrhea, or more serious side effects such as low blood sugar (in diabetic patients) or gallbladder problems.
During dose escalation, under-dosing can prolong the adjustment period and increase early nausea. Over-dosing can make side effects intolerable and lead to discontinuation. Precise delivery ensures the best balance between efficacy and tolerability.
The pen is designed to stop at the correct dose when dialed properly. Counting clicks is a backup verification method, not a replacement for reading the dose window.
Safe Injection Technique After Dialing
After dialing the correct number of clicks and confirming the dose window shows the prescribed mg, pinch a generous area of skin (abdomen, thigh, or upper arm). Insert the needle at a 90-degree angle and push the plunger slowly until it stops. Hold the button down for a full count of 6 seconds to ensure the full dose is delivered and to prevent leakage.
Withdraw the needle straight out and release the skin. Immediately dispose of the pen in a sharps container—never recap or reuse. Rotate sites weekly to prevent irritation or lipohypertrophy.
If the dose does not deliver fully (plunger stops early), do not attempt a second injection from the same pen that day. Contact your provider or pharmacist for guidance.
Injection Checklist
- Dial correct clicks and confirm mg in window
- Pinch skin and insert needle at 90 degrees
- Push plunger slowly and hold for 6 seconds
- Withdraw straight and dispose of pen safely
- Rotate injection sites each week
Following these steps ensures accurate delivery every time.
Conclusion
Each Wegovy pen uses the same mechanical click count regardless of strength: 18 clicks for 0.25 mg, 36 clicks for 0.5 mg, 72 clicks for 1 mg, 108 clicks for 1.7 mg, and 72 clicks for 2.4 mg. Accurate counting, combined with confirming the mg dose in the window, prevents under- or over-dosing. Always double-check the label, dial slowly, and follow the official injection technique.

Never rely on click counting alone—use the dose window as the primary guide and consult your healthcare provider or pharmacist for any uncertainty about your pen or dose.
FAQ
How many clicks is 0.25 mg on a Wegovy pen?
0.25 mg requires 18 clicks on any Wegovy pen. Turn the dial slowly and stop exactly at 18 clicks. The dose window should then display 0.25 mg.
Are the click counts the same for every Wegovy strength?
Yes. The click mechanism is identical across all Wegovy pens. The difference is the concentration of semaglutide per click, not the number of clicks needed for each labeled dose.
What happens if I dial too many clicks?
If you overshoot, do not dial backward. Dial past the maximum dose until the pen stops, then start over from zero and count again. Back-dialing can cause inaccurate delivery.
Can I use click counting instead of looking at the dose window?
No. Click counting is a helpful double-check, but the dose window showing the exact mg is the primary way to confirm the correct dose. Always verify both.
How do I practice counting clicks safely?
Use an empty training pen if your clinic provides one, or practice dialing to zero on your real pen without injecting. Count slowly and stop at the correct number each time until it feels natural.
What if the dose window does not match my prescribed mg after counting clicks?
Stop and do not inject. Recheck your click count and start over from zero. If the window still does not match, contact your pharmacist or prescriber immediately—there may be an issue with the pen.
Is it safe to split a higher-dose pen to get a lower dose using clicks?
Splitting doses (for example, using a 1 mg pen to deliver 0.5 mg) is off-label and not recommended by the manufacturer. It can lead to dosing errors. Only do this if your doctor explicitly instructs you and supervises the process.
How do I know if my Wegovy pen is working correctly?
After dialing the correct clicks, the dose window should clearly display the prescribed mg amount. The plunger should move smoothly when you inject, and you should feel resistance until the full dose is delivered.
What should I do if the pen skips clicks or feels stuck?
Do not force the dial. Remove the needle from your skin, dial back to zero, and start over. If the pen continues to malfunction, discard it and contact your pharmacy or prescriber for a replacement.
Can I rely on click counting if the dose window is hard to read?
Click counting is a backup verification method, but the dose window is the definitive indicator. If the window is unclear, use a magnifying glass or bright light. If you still cannot read it accurately, do not inject—contact your provider or pharmacist.
