I read that keeping insulin in the fridge like I have always done, summer and winter is a good idea but…injecting it very cold like it just came from the fridge would increase the scar tissue under the skin. Better to warm it a bit.
I never heard about the scar tissue issue caused by too cold insulin. Have you?

Also, diabetics who have had diabetes for some years, are you still having regular appointments regarding diabetes issues with your doctor?
Just asking because my doctor never asks me about my diabetes. Of course he sees my HG A1C all the time which has been good. Also my doctor asked me a couple of times to talk to a new diabetic to relax him/she. Did you find the same?

All these questions posed by JB. Isn't this exciting? LOL.

My Insulin comes in pre-filled pens and the directions attached with the prescription label says to refrigerate for storage. Once opened may be kept at room temperature.
I do that, even though it seems odd since most things are "Refrigerate after Opening".

And, since I am still new to Diabetes I am not sure about scars at the injections site. Right now my doctor only wants me injecting in the stomach. Hopefully as my BG numbers become more stable he will be okay with me injecting in a rotating pattern.

I don't use insulin, but I have another injection medication that's refrigerated and I was instructed to let the needle come to room temperature (about 20 minutes) before injecting. It's basically a comfort factor. I rotate on seven parts of my body, but I usually only hear of stomach and thighs with insulin, is that all you use?

I was never told that cold insulin could increase scar tissue, but that doesn't mean it's not true. I don't like for the insulin to be too cold, just because it feels weird going in. I have been diabetic for 13 years and for several years I kept giving my shots in only my stomach, and although I haven't given myself a shot there in almost a year, I still do have scar tissue…I'm sure you've been told it, but rotate! That's one way to avoid scar tissue.
My doctor does my blood work but she has stopped checking my feet and asking me diabetic related questions. . .but I think your doctor always should, hence I'm changing doctors. . .

I always keep my insulin in the fridge until its time to use it then I take it out and leave it out for the 28 days that I use it. I do this with both my insulins that I use so both are kept at room tempature after opening. I've had no problems with them and they work very well and don't hurt as bad as cold insulin. I've never had a problem with them spoiling in the winter or summer. I do believe its more comfortable to inject this way and as I mentioned they don't spoil either. The only time I keep it in the fridge is before opening.this works well for pharmasist told me its ok to do this and I've done it this way ever since I've been on insulin with both my insulins. I also have heard cold insulin does cause more scaring. The room temp insulin works out very well for me.

I always use to keep mine in the fridge, but I heard awhile ago from others here, that you only need to keep your insulin refrigerated until you open it. I haven't either had a problem with my insulin going bad. . .except for the one time I left a spare vial in the car during the summer for two days - that was a mistake, it fell out of my purse.

My husband was a diabetic for years on insulin. We always kept the insulin in the frig and when he was ready would take out a bottle (that stayed at room temp) until finished with the bottle. Never had spoliage.

I read something about too cold insulin being slightly more painful to inject but I haven't heard anything about scar tissue. Though I'm also new at this and I'm not insulin dependent either so I only know what I read online.

I also think talking to a more experienced diabetic is a good idea when you're new, I know I feel a lot better after reading about everyone here on this site and once I'm more experienced I would be happy to help others personally.

Thank you all for the replies. I now keep only my unused insulin (new bottles) in the fridge. Vails I use for one month and then discard it.

I have noticed a strenght difference when I keep using the after one month insulin. Seems such a waste to throw so much insulin to the fishes. Bet they have no diabetes at all! LOL.
