How to Calculate Wegovy Dose by Clicks
Wegovy (semaglutide) FlexTouch pens are mechanical devices that deliver medication based on internal clicks. While the pens are labeled for specific doses, many users need to calculate "clicks" to titrate doses or manage supply effectively under medical supervision.
The mathematical formula for calculating clicks is straightforward:
Formula: (Target Dose / Total Pen Strength) × Total Clicks per Pen = Clicks Needed
Step-by-Step Calculation Guide
Identify Pen Strength: Check your pen label for the total amount of mg. Common Wegovy strengths include 0.25mg, 0.5mg, 1.0mg, 1.7mg, and 2.4mg.
Determine Total Clicks: Most FlexTouch pens require 74 clicks to reach the full dose marked on the pen. You can verify this by "dialing up" a used pen to see how many clicks it takes to reach the end.
Select Target Dose: This is the amount of medication in mg that your doctor has instructed you to take.
Realistic Example:
If you have a 1.0mg pen and you only need a 0.25mg dose:
1. Total mg: 1.0
2. Total Clicks: 74
3. Math: (0.25 / 1.0) * 74 = 18.5 clicks (Round to 18 or 19 based on medical advice).
Common Wegovy Click Table (Estimated)
Assuming a standard 74-click pen, here are the approximate calculations for common titration steps:
0.25mg dose from 2.4mg pen: ~8 clicks
0.5mg dose from 2.4mg pen: ~15 clicks
1.0mg dose from 2.4mg pen: ~31 clicks
1.7mg dose from 2.4mg pen: ~52 clicks
Safety Precautions
When "click dosing," accuracy is vital. Always dial the pen slowly and listen for the distinct audible click. If you miscount, it is safer to dial back to zero (if your pen model allows) or carefully reset before attempting again. Using a pen for more than the intended 4 doses (30 days) may increase the risk of contamination or loss of potency; always consult your pharmacist regarding medication stability.
