I take 30 units of Lantus and I prime every time; however, I leave the needle tip on for the duration of that pen. I will change it if it starts to hurt. When I am done injecting I try to gently shake any leftover drops and put the pen cap back on. When I used Novolog I would also leave the needle tip on for a few days. I don't seem to have any adverse reactions to doing this.
Now I might test around with the prime vs no prime, droplet only too.

I would be interested to know if you see a difference since you don't change the pen needle each time. Just to clarify, I do change the pen needle each time, so I'm guessing that's why I am noticing a larger difference than those who reuse.

I use a new one each time because
* My insurance has a $0 co-pay for pen needles.
* I've found that I get fewer callouses when I use a fresh lancet each time, and assumed that fresh pen needles would also be easier on my skin.
* I haven't found a good way yet to keep the needle on and also recap the pen. When I tried just leaving the needle in without either of the BD needle caps, and it leaked insulin into the pen cap.

I already dosed tonite so I'll start tomorrow. I do have to pay for the tips, I think $72 for 90 days. I first read about leaving the tips on from this site so I tried it and it's been fine. When I was on the Novalog it was easier to leave on tip on for the day and that was it was easier when I was out (like at work or with friends). I don't think I tried it until after a couple of years. I will say that I noticed when I was on Levimer the pens would jam on me occasionally and I would have to change the tip but I've not had it happen with the Lantus. I have a long weekend this week so I'll play around and see what I find. I'll let you know then.
I also leave my lancet on for a week too. That is included in my insurance (I can't say it's free because I'm paying for it in my premiums no matter what they say). I just find it easier when at work or out to leave it on for the day.

Daytona, I tried it with my Lantus pen as I think there was less than a full dose left and usually I would finish that pen and start a new one to complete the dose but it was fun to experiment with the leftover instead. I was originally on Lantus, insurance switch to Levimer and then insurance switched back to Lantus. I like the Lantus pen better. The Levimer stuck on me more than once and the Lantus seems tighter and sturdier. I also got a welt at every injection with Levimer for a few days. If the reaction had progressed I would've switched. I let it be because 1. it was easy to tell where my last injection was and 2. It never progressed beyond the welt. 3. I didn't want to pay the higher co-pay for non-formulary.
Anyway, it's very unscientific testing but I've checked it about 5 times and each time to my naked eye the difference seems negligible. I injected 6 units each into little tin foil cups and then I tried in little plastic bags that I had. I'm still going to prime each time but I don't know that it matters with Lantus. I have a Novolog pen I experiment with later. If anyone can think of a more scientific way to test this I am open to any suggestions that I didn't think of.

Oooh, sounds like you may be allergic to Levemir! Yay for science, and thank you for testing. That's a good idea to test using the leftover before changing pens.

Pennysgirl, I am having more trouble with the Novolog pen. Sometimes, leaving the needle on without changing, I use 1u and it never beads on the top, try it again and it STILL does not. Now this does not happen with the Levemir. However, the jury is still out because one pen in this box was returned to the manufacturer because I had trouble pressing the button. This pen had the needle changed every use up until I called because I kept having to take it with me (you can't cap it with a needle cover). This may explain why 1-2u for a correction never works. For the rest of this pen, I will be changing needles every time and see if it makes any difference.

BTW, if you use a Timesulin cap, which I bought for my Levemir pen, you have no choice but to remove the needle - just like the regular cap, it won't go on with it installed. Sneaky designers..

Now you did it. I had to pull out my old Novolog pen (still had the needle on it) that I last used in May. This has been left out in a cool, dark place and it looks fine so I experimented with it. I did one unit without priming and it worked easily. I don't think I ever had problems with any Novolog pen. I'm sorry to hear that you are. I think the directions say to prime with 2 units first; but I might be remembering incorrectly.
Levimer jammed up on me more times than I like to remember. Atleast every other month or more. I sent them a note but never got a reply. I had other things going on so I never followed up. I can see where the Timesulin won't work. Drat!
I pulled out 3 clear needle caps (the outer ones) and I injected 6 u without priming in one and 6 units each in the other two after that. In a surprising twist the FIRST one (without the prime) measured 1/2 inch and the other two measured a little less. I was very surprised to say the least. I'm going to test throughout the weekend since I now have a Novolog pen to play, I mean test with too.

Let's say one is prescribed Lantus at 15 units a day. Lantus units are the same as pills. 30 pills for 30 days...then you get a refill. With Lantus the arithmetic is 300 units in the pen...divided by 15 units a day; is 20 days. Multiply that by 5 pens...that's 100 days before you can get a refill.

Trust me...the pharmacy knows your refill date.

Now, let's say you prime your pen that has a huge " pen needle with 2 units each time you use 15 units. In reality...that's 17 units. 17 units from a 300 unit pen lasts a little over 17 days. Multiply that by 5 pens and you get 87.5 days...not 100 days as your prescription says. You literally run out of insulin almost two weeks before you can order a refill.

Were this pills...with the same would be like throwing 4 pills away every 30 days.

So, tell me...wassup with this "prime" thing and how does your prescription deal with that? It doesn't. No prescription ever has added this "prime" thing into the equation...that I know of.

Bounty 08-14-2016 00:45

As an addendum here...when I used Lantus pens there were 308 units in the pen...not 300. Still...that would mean at least 10 days without insulin before you could refill.

Bunjee 08-14-2016 02:22

Bounty, talk to your pharmacist. Pick a day when they aren't that busy (i.e. Tues - Thur) and discuss how you are running out at 87.5 days instead of 100. At the very least, if you have a 90 day supply, you should be getting 90 days, but since most pharmacies only sell by the box, how are they handling this on the reorder? Have him/her explain to you - maybe they just need to adjust the reorder timing. I'm more than a box ahead and was just notified that I can reorder again.

Pennysgirl, I called the number on the pen rather than write anything.
