When youre out and about, at work wherever keep your insulin in a safe zipped-up kit and keep it in your purse or backpack.

Response From The Ada

Thank you for asking the ADA to respond to Dr. Grajowers letter. He raises several very important points regarding the storage of insulins and its possible effects on blood glucose control. His specific comments regarding the various insulins and what their manufacturers state regarding storage and product expirations will need to be addressed by the manufacturers themselves. If their guidelines were only evidence based, then they would have that data. I will comment on the general topic of insulin use as regards the guidelines that come from our 2003 Clinical Practice Recommendations. In general, patients are instructed that once opened, an insulin vial need not be refrigerated and can be kept at room temperature for 1 month. Extremes of temperature should be avoided because these can lead to significant changes in insulin action. How long an insulin can be stored while unopened is based on the expiration date.

Can Vetsulin Be Diluted

No. Vetsulin is a mixture of amorphous insulin and crystalline insulin. The crystalline part is relatively insoluble, which is why the insulin activity lasts more than a few hours. Vetsulin has a balance between the amorphous and crystalline parts. If Vetsulin is diluted, the balance between amorphous and crystalline parts is no longer 35% and 65%, relatively speaking. The amount of soluble insulin is increased by the aqueous diluent used. This results in an alteration of the pharmacokinetics of Vetsulin. With a larger aqueous fraction and smaller crystalline fraction, there would be a decrease in the crystalline portion responsible for the second peak of insulin activity.

Storage Guidelines: Vials Of Novolin R Novolin N Novolin 70/30 Novolin Lente Or Velosulin Br

The U.S. Pharmacopoeia Dispensing Information provides the following recommendations for storage of insulin vials: An insulin bottle in use may be kept at room temperature for up to 1 month. Insulin that has been kept at room temperature for longer than 1 month should be thrown away .

The ADA reminds health care professionals that even though each insulin vial is stamped with an expiration date, a slight loss of potency may occur after the vial has been in use for > 30 days, especially if stored at room temperature . If human insulin vials are stored under refrigeration while in use and are used beyond 30 days, the stability of these vials may be affected by a number of factors. Such factors include the number of injections per day, volume of insulin remaining in the vial, exposure to light, agitation, and technique used for dose preparation. The impact of such factors is difficult to measure, and the health care professional should advise patients on an individual basis concerning long-term storage of opened insulin vials when refrigerated.

Changes in insulin strength, manufacturer, type, species , or method of manufacture may result in the need for a change in dosage.

Insulin Storage In The Distribution Cold Chain

Insulin storage temperature is carefully managed and controlled in all steps of the supply chain by manufacturers, distributors, health care professionals , and health authorities. shows a simplified overview of quality assurance for the main stakeholders in the pharmaceutical cold chain. In distribution, insulin needs to be kept refrigerated between 2°C and 8°C to ensure optimal quality.

The World Health Organization , the European Commission, and USP issue Good Distribution Practice Guidelines, which regulate and advise on how to maintain the pharmaceutical cold chain.- These stipulate that pharmaceutical manufacturers are liable and responsible to recall insulin if possibly damaged. Manufacturers therefore make contracts with logistics companies and wholesalers, defining the conditions under which products are stored and transported, and often work closely together on risk assessment. Pharmacies and hospitals also report to manufacturers when temperature deviations occur, which are then assessed case by case and might result in recalling the packages in question or clearing them safe to dispense.

Response From Eli Lilly

We appreciate the opportunity to respond to Dr. Grajowers letter concerning in-use dating of insulin products manufactured by Eli Lilly. There are many issues affecting recommendations for storing insulin, and the labeling is controlled by global regulatory agencies, including the U.S. Food and Drug Administration. Considering the large number of factors that go into these recommendations, it is not surprising that there may be confusion about insulin potency during use.

When unopened vials, cartridges, or prefilled insulin pens are stored at the recommended temperatures , insulin may be used until the expiration date printed on the insulin container or carton. At expiry, regulatory requirements state that the insulin product must retain at least 95% of its labeled potency.

However, once an insulin product is in use, the recommended durations of in-use differ depending on the particular formulation of insulin , its primary container , the ambient storage conditions , and regulatory requirements.

Patients should not use insulins that have changed in appearance due to heat exposure or freezing. Freezing will cause modified insulins to resuspend improperly after thawing, reducing the accuracy of dosing.

Being Mindful Insulin Temperature In Day

Leaving your insulin in a hot car during July heat for 15 minutes while youre getting groceries probably wont destroy your insulin, but much longer definitely could. This is why its extremely important to be mindful about when and where you keep your opened insulin.

If insulin is exposed to very hot or very cold temperatures for too long even just 60 minutes it can break down very quickly, to the point of not having any real impact on your blood sugar.

Remember, 65 degrees outside can mean its 80 degrees in your car.

And on the flip-side, a cold winters day could mean the inside of your car or your jacket packet on the ski slope is 10 degrees, easily cold enough to destroy your insulin.

Where To Donate Expired Insulin

If you are not going to risk using expired insulin, the issue then becomes what can be done with it.

When I think of the people who cannot afford or struggle to get it, it just feels wrong to toss it out, Spector says.

Groups and programs like Life for a Child and Insulin for Life cannot, by law, accept expired insulin.

Other options do exist, though.

  • Many doctors and clinics are unable to take any donated insulin once its opened or at all, given the uncertainties of whether its already been compromised by the time theyd receive it. But this policy does depend on the particular doctors office or clinic, so its definitely worth calling around to ask.
  • Local animal hospitals may also accept expired insulin, depending on their policies and where they are located.
  • Private hand-offs are also possible. With the insulin affordability crisis in America, a growing black market has materialized where people within the community regularly donate various types of insulin to each other directly, or through grassroots efforts. The #insulin4all hashtag on social media is full of requests, as well as networks of people who focus on getting insulin donations to those in need. While this isnt technically legal, given that prescriptions should be not shared with those who are not prescribed, it is common within the D-Community, and

Things To Do When You Do Not Get A Toaster For Storing Insulin

Storing your insulin pen

Even though this could be a problem in more distant places, one tip is to set the insulin vial in a plastic bag, tie a rubber band around it and add it into an earthen pot or a wide-mouthed jar full of water.

Take the vial outside and maintain at room temperature, a minimum of 30 minutes before use.

What To Do With Expired Insulin

Its a dilemma just about every insulin-using person with diabetes has faced, for many a reason: What to do about expired insulin?

Take the mom of a child with diabetes who realizes at day 28 of an open insulin vial that theyve barely used half of it, but have reached the listed expiration date.

It feels so wasteful, that mother explained.

Or the young adult with type 1 diabetes struggling mightily to afford their insulin, so is tempted to stretch it out way past the formal cut-off date.

The longer I can make it last, the less chance I go broke, that young adult told DiabetesMine.

Or even sometimes a well-known endocrinologist, who finds himself faced with using expired insulin or none at all and chooses the former.

Funny you ask, says Dr. Stephen Ponder, a pediatric endocrinologist in Texas who lives with T1D himself. A year ago I forgot my rapid-acting insulin and found one vial in my office fridge. It expired in 2016 . I used it, and it worked as expected. Any time one does this, of course, we take a calculated risk.

The temptation is real be it for cost savings, convenience, or just plain not wanting to waste a liquid that quite literally costs more than its own weight in gold. Insulin users often find themselves questioning expiration dates.

Yet determining whether insulin is still good is nowhere near as simple as sniffing a milk carton, so how do you know?

Heres What The Companies Say

Time to ask the authors themselves. Heres the information we got, when calling the medical information hotlines of insulin manufacturers.

  • Sanofi: This is a precaution, because patients were injecting cold insulin and reported side effects of the injection site.
  • Lilly: When you return pen cartridges to the fridge from room temperature, air bubbles can form, which leads to injecting problems.
  • : We are changing this guideline back for disposable pens.

When asked what is worse: exposing insulin to heat or putting in back in a fridge?, all three sources agreed the fridge was the better option.

So the insulin itself is not affected by putting it back to the fridge! And this guideline exists only to prevent user mistakes?

Both injecting cold insulin and having air bubbles in the cartridge are of course inconvenient, but avoidable. Just remember to take insulin out of the fridge awhile before injecting and dont store pens with needle attached. You could argue, that these are things most people with diabetes would know. Was this worth changing the guidelines?

Novo Nordisks answer was definitely a surprise. They actually had already been changing the labels. Checking FDA label for Fiasp, their newest additions to the market, it says disposable FlexTouch pens in use can be refrigerated.

Happy now? No, wait a minute! So we established that keeping in-use insulin in the fridge is not affecting its quality.

Yes Insulin Does Expire

Medical insulin breaks down over time, which is why all insulin has an expiration date, says Maria Fernandez de Fiore, RN, a diabetes care and education specialist and Inpatient Diabetes Program Coordinator for Riverside University Health System in Moreno Valley, California.

“The expiration date means that the insulin will start to degrade after this date,” Fernandez de Fiore says. “It will go bad because it won’t be effective to manage blood glucose levels anymore.”

Specifically, this is because insulin proteins break down over time. Expired insulin won’t make you sick, but it will be less effective, and it can be dangerous to use.

“When it comes to insulin, we have to make sure it works at its full potency, or the blood glucose levels can go dangerously high,” Fernandez de Fiore says.
