: Using the same pen for many doses increases the risk of contamination, even when using fresh needles for every injection.
: Known to contain a higher total concentration of semaglutide, requiring a different, often higher, number of clicks to achieve lower, non-standard doses. 1.7 mg Pens how to calculate wegovy dose by clicks
Some people think they can dial 12 clicks, inject, then dial another 12 clicks later for a total of 24. The pen's internal mechanism is a screw. Once you push the button, the screw resets. You cannot "save" clicks. : Using the same pen for many doses
This paper provides a practical, actionable method to estimate Wegovy (semaglutide) doses using the number of pen “clicks” when dose markings are not used or when patients report clicks instead of mg. It describes the typical Wegovy injection device mechanics, assumptions needed, step-by-step calculations converting clicks to dose (mg and IU-equivalent volume), safe rounding and titration recommendations, monitoring considerations, and limitations. This is intended as a secondary method only when standard labeled dosing/visible markings or pharmacy guidance are unavailable. Always verify with the manufacturer, the dispensing pharmacy, or a clinician prior to dosing. The pen's internal mechanism is a screw
To calculate the Wegovy dose by clicks, follow these steps:
Look at the side of your Wegovy carton and pen. It will clearly state the maximum dose inside that specific pen (e.g., "0.25 mg/0.5 mL" or "1.0 mg/1.0 mL").
