The Lilly KwikPen is a disposable insulin pen. But a lot of people may not know, you can actually refill it and re-use it!

It’s very easy to do. Just two simple steps

Notice in this picture how the plunger is all the way to the top. This Kwikpen is empty. Also notice that the black advance screw is pressed up against the plunger.

This is the dosing button I am referring to:

Step 1:  
Hold the base of the pen. Push the dosing button **up into the base of the pen** , and while holding it up into the pen, turn the dosing button **counterclockwise**. This is the opposite direction you do when dialing up your dose. Keep pushing the button into the base of the pen and turning the dosing button counterclockwise. As you turn the dosing button, you will hear click sounds, and you will see the black advance screw moving away from the plunger.

Now, notice in this picture how the black advance screw is no longer pressed up against the plunger. Now you have space to put insulin back in the reservoir.

Step 2:  
Simply add your insulin. Just take an insulin syringe filled with insulin from a vial, and refill the reservoir. Now you can reuse the pen! If you see an air bubble in the reservoir, just use your syringe to withdraw the bubble.

Since this is just a simple demo, we don’t want to get into mixing different insulins or diluting. I will save that for another day.

Why do this?   
Vial insulin is cheaper than pens. And I have found that these disposable pens are one of the more expensive items!

But if you do the refill and reuse process just 3 times after the pen’s initial use, you have made it 1/4 of the price. 😉
