How Should Insulin Be Stored?

sealed box

Before First Use

All insulin formulations should be stored in a refrigerator at 36° to 46°F (2°-8°C) before use to keep their quality until the expiration date.

open box

After First Use

Insulin must be stored below 76-86°F (below 24-30°C), but should never be allowed to freeze and should not be exposed to direct sunlight.

Always Stay in the

Safe Zone

Insulin in use that is exposed to temperatures above 86°F or below freezing can be damaged and unsafe. Injecting damaged insulin can result in fluctuating glucose levels and can be life threatening, or cause unpleasant side effects.

As a clinician and clinical investigator concerned about better treatments for diabetes, the VIVI Cap is of particular benefit for my patients who require insulin shots, as the vast majority of patients use insulin pens for their daily injections.
Dr. Diana Isaacs ADCES Diabetes Educator
of the Year 2020
Most people don't realize how fragile insulin is, and how to store it for it to work the most effectively. The VIVI Cap is an incredibly simple solution to ensure that insulin is safe to use and that none of it goes to waste
Dr. Susan B. Sloane Pharmacist, Diabetes Care and
Education Specialist
I was so excited to find the VIVI Cap products. Temperature extremes affect Insulin and once that happens, the blood sugar controls get out of hand. I really think it's a life-saving product. Plus, it's all FDA registered and very easy to use.

Proven Ability To Protect From Extreme High or Low Temperatures

Pfützner et al. ATTD Feb 2018

Did You Know: The FDA allows insulin to lose up to 5% potency, even in perfect storage conditions.

In less than perfect conditions the potency loss can be much higher, causing unpredictable swings in blood sugar.

VIVI Cap is scientifically proven to protect insulin when exposed to high heat over 5 days. See the chart comparing insulin potency with and without VIVI Cap
