Storage Of Unopened Insulin:

Insulin Vial Instruction – 2015

Insulin is very sensitive to sunlight, indoor lights, and to extremely hot or cold temperatures.

Insulin is not OK to use if exposed to very hot or cold weather. The three drug manufacturers of insulin in the United States say UNOPENED insulin is best stored inside the fridge . UNOPENED insulin stored in the refrigerator is good until the expiration date printed on the insulin box. The expiration date will usually be 1 year from the date of purchase but you have to check the box to find ou

Cartridges for an insulin pump as seen above are also best stored inside the fridge and will last until the expiration date.

Storage of OPENED insulin:

Once open there are different storage needs for insulin. What does OPEN mean? This does NOT mean removed from the box. OPEN means the insulin cap is removed and the rubber stopper was punctured.


Vials and pens have different needs for storage. These differences can lead to confusion. Therefore, it is very important for you to become familiar with the recommendations for the insulin product that you use.

What is an OPEN vial?

Vial: Once the vial is punctured, it is OPEN. Once you stick a needle in the vial, it is OPEN. OPEN vials can be stored in the fridge or at CONTROLLED room temperature. Regardless of where it is stored, OPEN insulin will only last 28 days before it must be thrown away. Insulin kept in the fridge should be removed and allowed to reach room temperature before injection.

How Long Does Insulin Last In An Insulin Pump When Opened/in

If one uses open vials to draw insulin and refill an insulin pump, it can be a bit riskier. This is because once open, or when in use, insulin lasts for 28 days, after which it should be discarded.

Unlike unopened insulin, which needs to be refrigerated, opened insulin can be kept in controlled room temperatures or refrigerated.

But regardless of whether theyre stored at the right temperature, they have to be discarded after 28 days.


So, to know how long insulin will last in an insulin pump, its always recommended to record the date of when the insulin is opened. This will make sure that youre not refilling an insulin pump with insulin that has passed these 28 days of the lasting period.

If youre refilling with opened insulin thats reaching the last few days of use, then the insulin thats refilled in the pump may not last for long enough.

This is also one of the reasons why many users prefer using prefilled insulin cartridges. Rather than having to manually draw from vials and worry about how many days its been since opening the vial, patients can simply look at the date on the prefilled cartridge.

If this seems like an easier method for you, then for your fast-acting insulin, you can explore the option and potentially obtain it through our PAP for diabetes option for just $50 a month via Prescription Hope.

An open insulin vial or pen can be kept at room temperature between 59 and 86 degrees Fahrenheit to prevent it from going bad sooner than the 28-30 day period.


How Do I Store Unopened Insulin Bottles

Store newly purchased, unopened bottles of insulin in the refrigerator in their original carton to keep them clean and protected from light. When you’re ready to use a bottle of insulin, you can remove it from the fridge and generally keep it at room temperature for up to one month. But the sterility and potency of an opened bottle of insulin are affected by the number of insulin injections per day, the volume of insulin remaining in the bottle and exposure to light and agitation. For this reason, it’s important to discuss your insulin dosage and storageand review patient information available on the insulin manufacturers websitewith the doctor treating your diabetes. You should also check opened bottles of insulin carefully for discoloration or particles. Never store insulin in the freezer or in direct sunlight and always be sure to check the expiration date.

Lantus For Type 1 Diabetes

Lantus is approved by the FDA to improve blood sugar levels in adults and children with type 1 diabetes.

Type 1 diabetes is a chronic condition where your pancreas doesnt make insulin. Your body needs the hormone insulin to bring sugar into your cells, where sugar is used for energy. Without insulin, your cells cant get the energy they need to work properly. It also leads to high blood sugar levels, which can cause serious problems if not treated.

People with type 1 diabetes need to take insulin to survive.


Note: Lantus isnt approved to treat DKA, which is a possible complication of diabetes. For more information about DKA, see the Common questions about Lantus section below.

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.

Lantus and certain diabetes medications

Taking Lantus with other diabetes medications can increase your risk for hypoglycemia . If you take Lantus with other diabetes drugs, your doctor may need to adjust your dosage of one or all of them to reduce your risk for low blood sugar. They may also want you to monitor your blood sugar levels more often.

Examples of other diabetes medications that can increase your risk for low blood sugar if taken with Lantus include:

Can Expired Insulin Be Harmful

Introduction to Insulin: Vial (bottle) & Syringe Injections

You shouldn’t use expired insulin. “I recommend to never use insulin if it’s expired, under any circumstance,” Fernandez de Fiore says.

When your doctor prescribes you insulin, they will give you a certain dose and potency. If the insulin has broken down, it will be less potent, and not give you the blood sugar control you need. This could lead to high blood sugar, or hyperglycemia.

There are also a few conditions that can cause insulin to expire early. This can happen if the insulin is not stored properly or has been exposed to room temperature or light, both of which can degrade the insulin.

Before you inject insulin, you should check the insulin’s appearance. If you notice any of the following signs, it should be returned to the pharmacy.


  • Discoloration or cloudy appearance to regular insulin
  • Clumps in the insulin
  • “Frosting” or crystals on the inside of the vial

In order to make sure that your insulin doesn’t go bad before it’s expiration, following these storage recommendations, says Fernandez de Fiore.

  • Store unopened insulin in the fridge at a temperature between 36 and 46 degrees Fahrenheit
  • Store opened insulin that’s being used at room temperature, between 56 and 80 degrees Fahrenheit
  • Store insulin out of sunlight
  • Never freeze insulin or keep it in a hot area, like the glove compartment of a car

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.

Is An Insulin Pen Right For Me

Insulin pens can be beneficial for many people with diabetes, but understandably they may not be suitable for all people with diabetes. Diabetes treatment plans should always be individualized and take multiple variables into consideration, including a persons health literacy, financial situation, access to supplies, lifestyle, willingness, and desire of use.

Don’t Miss: Is Diabetes Type 2 Hereditary

Why Opened Insulin Expires Before The Actual Expiration Date

When insulin is opened, the efficacy of insulin begins to degrade over time. So, patients that inject insulin after it has been opened and unrefrigerated longer than 28 days may experience high blood sugar levels.

Individuals using insulin beyond the expiration date may try taking more insulin per dose to get the same effect. Doing this puts a person at risk of hypoglycemia, which can be life-threatening.

Note If you are using insulin vials and are unable to use the entirety of the vial before the 28 days is up, then consider switching from vials to insulin pens. Insulin pens carry less insulin volume, which means youre more likely to use them up before 28 days after opening. This way you are note wasting insulin that you have paid for.

Can Insulin Vials Be Kept Safely Outside The Refrigerator

How Long Does A Vial Of Insulin Last

Q. I am on a website where information is exchanged between people with type 1 diabetes. Half the people say that insulin doesnât need refrigeration after it is opened and half say that it still needs refrigeration. After having diabetes for 42 years, I have never heard that keeping insulin at room temperature is okay. Is it? Doesnât temperature affect how well the insulin works? A. The American Diabetes Association recommends that a bottle of insulin can be stored at room temperature for up to one month after it is opened. Storing it in the refrigerator after opening does not make it last longer. Unopened insulin can be stored at room temperature for one month or in the refrigerator until it reaches its expiration date. Insulin must be protected from extremes of heat or cold, which means not leaving it in the glove box or trunk of the car during the summer. Mail order delivery can pose problems. One reader had a delivery of insulin sit outside for hours in the winter. The pharmacy told her it should be fine, but it did not control her blood sugar properly. If you get your insulin by mail order, check with the pharmacy to verify that it will not sit in a hot delivery truck or mailbox in warm weather.Continue reading > >

These containers are usually yellow and are available through pharmacies, local municipal councils and state or territory diabetes organisations such as Diabetes Victoria.

Procedures to dispose of sharps containers vary from state to state.

With so many different insulin and insulin-like products out there these days it can be hard to keep track of when your vial should be tossed.

Depending on your dose, you may still have insulin left in your vial by the manufacturer-recommended time to throw it away. If this sounds like a familiar situation, know that it is important to throw away your vial regardless of whether you have any leftover.
