Hi Everyone,
I have the presription and I am going to order online but they
have the penfill catridge or the flex pen
Does anyone know the difference?
any preference...I would actually prefer the vial...do you know where I can get that from?
Thanks for your help!
 
Hi Denise,
I think most use the flex pen. I believe I'm the only one that still uses the vial. :lol: The pens are more cost efficient, althought cost more up front, and they last longer. I have been able to use the vial for...7 or 8 months and then I get nervous that it's pooping out and crack open a new one. People that use the pens have been able to use to the very last drop.

Here's a visual of the pens and cartridges:

I'd get pen-fills over carts because it gives you a "holder" for the cart (pen-fill is the cart encased in a pen with a cap), and protects it more. It's easier to hold when you draw the dose then a cart.

And both will last longer than a vial, as Marcy points out. I have used my penfills (and carts) to the last drop every time and with small doses under 1u (for both boys) they last a long time!

Are you ordering from Canadadrugsonline.com? If so, I do believe they order the flex pens from Turkey or somewhere, so it can take up to three weeks or so. I think the cartridges they send out locally and I think it takes about a week.

Now I could very well be wrong about this since it has been a while since I ordered any carts, so someone please correct me if I am wrong.

Not sure if you have seen this thread on Health:
