I had similar situations with Levemir and HUmalog pens. it stopped when they remade the Humaog ones. The new pens work fantastic, but the Levemir< up until I got a pump would often just stick and you couldn't use them at all in any way, shape or form.
I have had problems with the pens also. I have had times where the mechanism seems to stick or hang up. I haven't seen that kind of problem lately but I occasionally I have trouble depressing the plunger. I have found this happens when I inject into and area that I have used way to frequently. It seems this area has become tough and hard to inject into.
Yes I do Holger, here in Amnerica they have quit making the Novolog cartriges, available ,they only provide the throw away pens. Which have a poor action. I use a Novopen 4 which I bought from the UK but I have to remove the cartridge and snap on the threade cap as you show in your picture.
Really? Are they mad?
You should consult a lawyer to check if this is enough for a lawsuite against Novo.
a) the throw away pens are much more unreliable.
b) the throw away pens create immense waste.
c) the throw away pens increase the costs for insurance companies and patients. Because of that you should ask your lawyer to contact insurance companies about this. This will increase the money value of the lawsuit by magnitudes. Your lawyer will love it.
You will win. I really mean it!
You may want to check out the NovoPen Jr. It is a metal refillable pen that takes Novolog cartridges. (I use it because it allows half-unit dosing.) Have only been using insulin for a little while, so I can't tell you how it compares to anything else....
But Donald claims that NovoLog has stopped to sell these Cartridges in the USA. I can not image that this is possible but read his remarks.
I'm in the US and am using them. I think the issue is that the cartridges are only for the kids' pen. And also not pushed much by the reps. My doctor didn't even know about the NovoPen Jr until we looked into what could dose in smaller units. The Novo rep was in the office later that day and he verified it. The pharmacy did need to special-order both the cartridges and the pen casing, though, as it's more unusual.
But all NovoPens use the same cartridge. The difference is just in the mechanics to provide 1/2 increments VS 1 unit increments.
I had problems with mine. When I would push down the plunger to inject the insulin, it would seem to "slide" a little, then start clicking as the numbers counted down. I couldn't tell if I was getting insulin at the first part of the injection or not. I called the company and they said they found some small dust like things(?) in it causing the problem. I was told to not carry the pen in my pocket or in a bag because that could cause problems. They kept my pen I had sent in (almost full of insulin) and didn't replace it. I got another brand new one out of a box with a different lot number. It did the same thing. I've since stopped using them. I could never trust for sure I was getting the right amount of insulin, and the company didn't seem very reassuring about it. I figured it must be just cheap parts or something...
I really like my novopen 4, I have 3 of them. The plastic pen cant compare.
The problem is that I take my lantus and that is a different size cartridge so I have to put up with the poor quality plastic pen.
I will have to check on cartriges for the novopen jr, I have seen the pen but just figured they did not make those available either
They do still make the cartridges for the Novopen products. The same cartridge is used for Novopen and Novopen Jr. I recently had someone else say they couldn't get them (cartridges) anymore. I called the pharmacy and the pharmacy manager said their particular pharmacy would not be getting them anymore because there were so few patients that had them prescribed which made the price too much. Like roodgirl I also confirmed with the Novo reps that the cartridges are still available and there is no plan to phase them out that they are aware of.
