How to refill a (non-refillable) NovoLog FlexPen with a NovoLog PenFill cartridge 

Thank you so much!! Incredible tutorial. You just saved me after my pharmacy sent the wrong prescription!!

I wasn't pressing both pieces together strongly enough at the end of the process (5:23). Thank you. Great vid.

You're the best, I managed to do it properly,thank you very much, Mr Mosia I am.health care workers from South Africa

Thankyou,... thankyou.... thankyou !!! You are a lifesavere. It worked two out of three times. One time, I must have wiggled it the wrong way, or something, the cartridge just wouldn't fit. Well actually, I just couldn't snap back the two parts together. But, heck, this is my third cartridge. I am just alternating two empties, until I run out of cartridges. Awesome!!! I have done the syringe thingy too. Works fine. I also had a very very old, like almost 26 yrs old HUMAPEN-HD Luxury Edition in my museum of old cameras and old insulin injection devices. The cartridge fit almost perfectly in it. A bit tight,at the top, but I could take injections. I have all kind of insulin devices in my museum. A needleless injection device (Yep! Just like in Startrek), And a Insulin inhaler just like the inhaler for asthama, only as large as a small water pump (which you use to pump water out the window when your basement gets flooded. LOL) That insulin was in powder form in a foil strip, just like some BG Test strips individually rapped in foil, that you insert in the device and it punctures it and fills the air inside with the power. Then you press the plunger as you breat through the nozel in your mouth. I am just waiting for, some day, candies filled with swallowable insulin, or some oral form of medicine :D

thank u, this was soooooo helpful. it took 4 of us but thank God for ur video.

thank you, you are a lifesaver. one note: when opening the pen, use more wiggling and less force, i managed to break the glass at first. next pen worked flawlessly!

Thank you so much for this video, this literally happened to me with my doctor sending the wrong prescription. I was able to follow all of your instructions, it worked!!!! Thank you! ☺️

I knew it was doable, just couldn't figure out how. I had the same issue with insulin pump cartridges. Thank you!!

Thank you so much. You saved me really.

Worked. Thank you

Thank you so much!

You are a legend 💯 thank you very much for sharing your moves 😉 you helped me man 🫡

Thnks man..u saved my $20

Thanks man.it worked

thankyou so much

You can also use penfills from Tresiba in the Novorapid case. I got refills from my doctor but you can’t do it with regular Tresiba pens

Thank you sir

many thanks

Did it, thanks 🙏

Thank you so much I just had that happen

Worked 😃💗

Thankyou ,🙂 so much

It is very easy to do now, going back to buying the Novarapid Penfill at 1826 as opposed to Novorapid Flex pen @ 3345 per 5

When you do the wiggle part to releasethe2 parts. Becareful because the glass inside will crack and break.

Thanks 💚💚💚💚

Is it any cheaper to get the refill cartridges over the flex pens themselves? Or are they the same regardless? Great vid! Thx!

Does it work for the refill of alternate brands, say Lantus? If the height of refill is not precisely the same?

Can you refill the insuline itself. I'm cheap and getting put on to the pump, and wantto carry an insuline pen as a backup.

Amazing because the catridges are cheaper per 5 than the prefilled Novarapid pens here in Thailand

Can you do this with a saxenda pen? I want to use it for mesotherapy

A very useful video, but I'd suggest not to remove the label if it fits a since if the vial was accidentally bought broken, all the insulin would leak out from the cracks on the glass wall while administering the insulin.

thank you so much for this very helpful video! I was wondering will it work on the Novarapid Pen and not the NovoLog?

can non refill change to refill?

Why is it spilling out when i put the needle?

I have empty nonrefillable pens. Can I refill the empty cartridge with insulin from a vial?

🙏🏽🙏🏽🙏🏽

What to do if there is no needle

SAME IS HAPPENING RIGHT NOW! I was prescribed a penfill. WTF

Not at all easy, too many steps, use of brute force in detataching parts might break them. Not user friendly for the elderly who might live alone .
