What is the effect on insulin if it gets too hot.
Does it stop working?

Thank you for all your comments. Even though it was clear, I decided to be on the side side and toss it. It only had a couple of days left on it. I think I will keep them in the refrigerator fro now on. Vegas weather is too unpredictable this time of year. Better be safe than sorry.

Someone on here compared open insulin to fish, and I like the analogy. It is a perishable and temperature sensitive product. If it gets too hot, it goes bad. However, if you keep it at no more than around 80 degrees, they say it is safe to use for about a month.
Comparing it to fish that has been allowed to get hot, I would say that you are taking a chance if you use it after it has had a chance to spoil. BUT, a short time being allowed to get hot does not automaticaly mean it has gone bad. You are taking a chance using it though.
If you chance it, use it, and nothing happens, you are probably okay. But on the other hand, is it worth the risk of using possible spoiled insulin?
Totaly up to you.
I almost totaly forgot.. what you look out for is to see if it has what looks like bits of grit in it. If it does, and they do not disolve after you gently shake it, then your insulin is not safe to use. at least, that is how my Novalin works. Other types of insulin may have differant characteristics.

It's unlikely that an air temperature of 90 would heat the insulin up enough to make it go bad, but if you see some unusual or erratic blood sugars then toss it and open a new vial/pen.

It becomes ineffective if it becomes either too hot or too cold.

The air conditioner in my house broken and it was 90+ on my house.
The insulin was on the counter. It is still clear, Would it be better to toss it than use it?

I take it, it was SUPPOSED to be clear?

Mine is supposed to be cloudy. If it is not when I roll the vial 'tween my palms then it's no good.
