How do I know if my Ozempic pen is empty?

The easiest way to tell if your Ozempic pen is empty is to remove the cap and check the window on the side of the pen. With an unused pen, you will see that this window is filled with a clear liquid, the medication you inject each week. If you can’t see any liquid in the window, then your pen is empty. Another way to tell that your Ozempic pen is empty is to turn the dose selector. If you can’t turn the dose selector, the pen is empty. 

The dose selector is also helpful to determine how much solution is left. Turn the dose selector until the dose counter stops. If you’re using a 0.5 mg Ozempic pen and the dose counter stops before 0.5 mg, there is not enough solution left for a full dose of 0.5 mg. In that case, it means you have already taken four doses of that 0.5 mg pen, and it’s time to start a new pen.
