Question 1

Can I use this for brand-name pens like Ozempic or Mounjaro?

Accepted Answer

No. Commercial brand-name pens are designed as fixed-dose delivery systems. While some users attempt to count clicks, the manufacturers do not support this, and the volume per click may not be linear or consistent across different pen types. This tool is for adjustable or compounded pens where the manufacturer specifies a fixed volume per click.

Question 2

How do I find the volume per click?

Accepted Answer

The volume per click is usually provided in the manufacturer's documentation for adjustable pens. It is often a very small volume, such as 0.01 mL or 0.0125 mL per click.

Question 3

What if my dose doesn't land on a whole click?

Accepted Answer

The calculator rounds to the nearest whole click. Mechanical pens generally only allow for whole-click increments. The tool shows the actual mg dose delivered by that rounded number of clicks so you can see the variance.

Question 4

Is this a medical recommendation?

Accepted Answer

No. This tool is for educational purposes only. Always follow the specific dosing instructions provided by your healthcare provider and the medication manufacturer. Never adjust your dose without clinical supervision.
