I keep my house @ 69 degrees and I still put my insulin in the refrigerator to save $$$, If you keep it @ 80 degrees about 10% of it will be dead in 30 days. (hence the 30 day "expired" rule) You'll read opinions about crystallization and degradation regarding insulin expiration, but the truth is; insulin is alive and it is very sensitive to heat.(shaking it can kill some of it also)

If you are not throwing any insulin away and buying more this is irrelevant. However, many diabetic throw away surplus insulin and buy more every month. You can ask any pharmacist because they all know if you keep you insulin between 36-46 degrees it will remain viable for years.

This is why most insulin have an expiration date on the box that is two years out. Which is based on refrigerated storage. The 30 day rule is based on room temperature air storage.

RE: Insulin, Inject cold or at room temp?
For what my opinion is worth, before I have to fill the cartridge in my insulin pump, I remove the vial of insulin from the refrigerator and place it on the table for a half hour. It then becomes room temperature (75) and I have less 'air bubbles' in the filling process to contend with. My CDE had advised me that once the vial is open it is good for 30 days at room temperature. However since much of the country is currently having a heat wave and insulin is very expensive, I go with keeping the vials of insulin in the refrigerator.

I also take the extended release version of Metformin (Metformin ER) and when I first started taking it I had a lot of Metformin "moments". Now it works better for me if I take it with a meal.

Your opinion is valued. WOW, tell me about the heat wave. We've been hitting 105 F.
It might be better today (a little). We also have smoke in the air from a wildfire near Santa Clarita.

RE: Insulin, Inject cold or at room temp?
Warming insulin is a comfort thing according to my doc. It doesn't work any different if injected cold or warm. So, if it doesn't bother you, go ahead and use it out of the fridge. Sensitivity, needle size and quantity of insulin all make a difference.

Due to the heat (96 F), I just left my insulin pen at home one day because I had no darn ice cubes to make a cool pack. I just cut way back on the carbs - got to 168. Have ice cubes for next week! Insulin is not supposed to be above 86 F - which is darned easy to do in the summer even when you don't leave your pen in the car.

How many milliliters of fluid do you inject? It seems to me that injected under the skin, the solution would reach body temperature rather rapidly. Try putting a few drops of cold water in your hand and see how quickly it warms up.

I would think that after a minute or so, cold insulin would be warm and would work the same as if you just waited one minute before injecting warm insulin.

Is cold insulin that uncomfortable? What do you feel?

RE: Insulin, Inject cold or at room temp?
For me, the largest injection of the day is 0.46 ml of 100U/ml Lantus long acting (basal) insulin.
Then there are the rapid onset, short duration insulin shots that are typically between 0.12 and 0.18 ml of 100U/ml.

Frankly I do not feel the injection.

( A full syringe would be a milliliter.)

There is a product on the market that uses cold water to activate the cooling properties and you can place an insulin pen or a vial of insulin in it to keep it cool. I place my insulin pump inside one of these pouches whilst I mow lawn. Since my husband and I have a large lawn to mow and it takes 3-4 hours to complete, having my pump in a cool environment is something that helps keep the insulin from degrading. The cost of one of these pouches (and they come in different sizes) is nominal considering the cost of insulin if you have to replace it.

RE: Insulin, Inject cold or at room temp?
This is why I have never considered getting the pump. I would be taking in off many times during the day to keep the insulin cold.

The recommendations to keep the "open" insulin between 56 and 86 degrees (room temperature)is based on establishing a reoccurring distribution system that replenishes you insulin supply ever thirty days.

Lower those temperature to 40-70 degrees and you double the life of your insulin. 60 days verses 30

Insulin degrades on a sliding scale. I never let mine get above
72 degrees.
