Has anybody else had problems with faulty Novorapid Flexpens. I had a faulty batch a few months ago, I'd start using them and after a few injections they'd jam up and refused to work. Since then things have seemed ok until today. Tested predinner and my BGs was 13.7 - didn't have a clue why as things have been pretty stable recently. But, then I tried injecting and the button wouldn't depress and I couldn't get anything out. Tried another pen - first two units came out or so I think then the pen jammed and wouldn't depress further. Tried another pen - wouldn't work at all. So got my husband to try the final pen in case it was me and that wouldn't work either. So, I've got no Novorapid and can't do anything till the morning when the GP reopens.

If you are out of insulin ring the out of hours GP service who are usually based in the hospital and see if they can get you some.  They should be able to.

BTW are you talking about the pre-filled pens?

I don't know what area you're in but do you know anyone else nearby on Novorapid if the above fails?

Patti Yes I'm out of Novorapid and they are pre-filled pens as I've had discard 4 tonight. Don't know anybody else on it, but I think I'll survive till morning, I had a very low carb tea and the 2 units I got out held me steady as I've just tested and I'm 13.6. I'll get the GP to issue a new prescription tomorrow and I'll mention the problem to the Pharmacy in case all their stock is the same.

very odd Terrie, I was on the pre-filled pens for 5 years and never had one that malfunctioned to that degree.  I would also suggest you ring Novonordisk and complain... and they will prolly ask for the pens back to test.  Which may help others in the future.  I had similar probs with Apidra.

I've had it with an odd pen or two, but not an enture box!!!  Hope you still have the box or summat with the batch etc you can quote at NovoNordisk?

I'd try and get the pharmacist to ring em, Boots did  that for me once with a faulty batch of insulin - they withdrew it!!!

Yes, my wife has had similar problems with NovoRapid 3ml flexpens.  Looking at the pen barrel, there is a rubber plunger, then a white circular pad, then a plastic screwed shaft.  The idea is that the tip of the screwed shaft pushes the white pad and that pushes the plunger and that pushes out the insulin.  Looking at my wife's pen, the screwed shaft was angled off centre on the white pad.  If this gets too bad, it seems the white pad can actually turn out of position, the pen will not then work.  She gently tapped the pen to get it back in line and, in one case, it worked.  In the other case, she saw that the pad was out of line and probably it was also jamming the screwed shaft.  The effect was to deliver a smaller quantity of insulin than expected, then to jam up completely.

For what it is worth, I think the problem is that the end of the screwed shaft is not properly registering in the centre of the white pad; it may lack positive location.  That's how things could get out of line - at least, that's how it looks.  Someone at Novo Nordisk should be onto this.  We reported the problem twice at our pharmacy but they seemed unable to report it, even though it is attached to a large health centre and has many patients using these pens.

It may be that people just see that their pen has gone wrong and throw it away without reporting the fault.  Our pharmacy said they had not had any other reports.  It is clearly only an occasional event but it can cause real problems and possibly some hazard.

Thanks Mostyn, not just me then LOL

TBH I went years before I had probs, now I get a 'sticky' pen every two or 3 boxes.

I think I'll see if I change to Humalog Iin which case the memoir anyway), if not I think I'll get a decent cartridge pen again instead of the throwaway ones.

OR if you are happy with Novorapid you could use the Novopen 4 Sedge.  I know you are happy with Levemir so I suggest you get the refillable pen for that at least.

Yeas Patti, it's the Novopen I was thinking of.

But as you know I have been toying with the Memoir - but maybe that's a bit drastic and I shouldn't change insulin if there is nothing really wrong with the one I am actually using - I am always concerned about the antibodies thing that happened to me before, just feel maybe I should change as little as possible to stay on the safe side .......

I don't mean to butt into a discussion here, but several times when I first started on a pre-filled Humalog pen I had trouble with it dispensing insulin too.  I took a regular syringe (the kind that you draw insulin from the vial) and 'withdrew' the units I needed from the pre-filled pen.  I had to be very careful not to put but just a wee bit of air into the pre-filled or I would wreck the mechanism.  Don't know if this would apply to your pen, but thought I would add my 2 pence worth.

I've still got a box on the back of the shelf somewhere (pretty sure they are out of date by now) which I keep in case of pen failure.

I had no idea disposable pens were so prone to failure. Scary!

Jenny - a similiar situation happened to me that happened to Terrie (whilst I was on MDI before the pump).  Only thing different was that the chemist store was still open, and in the U.S. you can buy a pkg of 10 syringes w/o a script.  So that is what I did, bought a pkg of 10 and used that all weekend until the Doctor's office opened on Monday morning.

I also have syringes available at home here even with the pump.  My BG tend to be quite erratic and my diabetes educator advised me to have separates syringes for those time when you need to head off a high blood glucose reading of 250 (13. or more.  Actually anything over 200 (11) gets my attention quickly enough.  Been having those kind of reading a LOT lately because of steroid ear drops this new Doc has prescribed for me.  Really glad to have syringes on hand for that - it gets the insulin into my body faster than the pump.

Oh - I thought you would just tell the pump to bolus immediately in that case?

Why/how is it slower then?

Jenny - I apologize for confusing you.  You are correct in thinking that you can tell the pump to "bolus" immediately.  However, the insulin comes more slowly from the infusion cannula than it does when you "shoot" it from a syringe.  With a syringe, once you press the plunger on the syringe the jab is done.  With a pump, the cannula delivers the insulin more slowly and steadily and many people prefer to do a separate jab when they have high blood sugars.  Hope I haven't managed to confuse you even more.
