Direct answer: There is no FDA-labeled click-to-milligram calculator for US Wegovy pens. Each single-use pen contains one preset dose. The two audible clicks indicate injection progress; they are not dose units, and stopping after a chosen number of clicks is not an approved way to create a partial dose.
What the two clicks actually mean
| Signal | Manufacturer explanation |
|---|---|
| First click | The injection has started |
| Second click | The injection is still in progress; keep applying pressure |
| Yellow bar stops moving | The preset dose has finished delivering |
Neither click selects a fraction of the medicine. Removing the pen early can result in an incomplete dose, but the number of clicks does not reveal how many milligrams entered the body.
How US Wegovy injection doses are selected
The current US prescribing information lists prefilled, single-dose pens that deliver a preset labeled strength. The dose is selected by prescribing and dispensing the correct presentation—not by turning a dose selector or counting sounds.
The label's injection strengths include 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg, and Wegovy HD 7.2 mg. The prescribed schedule and indication determine which strengths are appropriate; the list is not a self-titration chart.
Why online click charts are unsafe
- They may confuse US single-dose Wegovy with a different semaglutide product or a device sold in another country.
- They assume each audible or mechanical event represents a fixed volume, which US instructions do not establish.
- They can encourage partial delivery, pen reuse, or dose changes outside the prescription.
- They may be outdated when manufacturers add or change presentations.
Do not apply an Ozempic, compounded-semaglutide, or non-US pen chart to a US Wegovy single-dose pen.

Contact the prescriber before the next dose rather than trying to deliver part of a pen. The prescribing information includes an escalation schedule and allows a clinician to delay escalation when a dose is not tolerated. Severe or persistent vomiting, dehydration, severe abdominal pain, or signs of an allergic reaction need prompt medical advice.
What to do after an incomplete injection
If medicine appears on the skin, the yellow bar did not stop, the pen was removed early, or the device did not work as expected, do not estimate the missing amount or immediately inject another pen. Keep the device and package information and contact the prescriber, pharmacist, or manufacturer for product-specific guidance.
Devices outside the United States
Wegovy presentations and instructions can differ by country. Use the patient leaflet supplied with the exact device and the local regulator's current product information. This page describes the current US single-dose pen and should not be used as a global device guide.
Frequently asked questions
How many milligrams are in one Wegovy click?
US FDA-approved instructions do not assign a milligram amount to an audible click.
Can I stop after one click for half a dose?
No. The first click means injection has started; it is not a half-dose marker.
Does a US Wegovy pen contain multiple doses?
No. The current US pen is single use and contains one preset dose.
Can I use an Ozempic click chart for Wegovy?
No. These are different labeled products and device instructions are not interchangeable.
