My pen has locked!

I have three weeks left and I’ve just gone to insert and it won’t go in and appears locked! Is there a way to fix this or do I need to ask for a replacement pen?

Change the needle. (Put it on straight so the the inner needle doesn't bend.)

Yep, agree. If this is a Mounjaro pen, new needle and then check that it primes ok.

You could buy those needles people were using to get the “bonus dose” out.

Thanks all - new needle worked!

Out of curiosity, why would anyone use an old needle in an injection?!? It is a risk to get an infection.

No one has suggested using an old needle @Sunnyskiesa ? The OP attached a new needle, it was incorrectly attached so she replaced it with a second new needle.

As in a second new needle. Obviously I’d never use a needle more then once!
