You Could Be in Danger of Using Damaged Insulin

Without Even Knowing It...

Dr. Susan B. Sloane, Explains:
Pharmacist, Diabetes Care and Education Specialist

Insulin must be protected from temperature extremes. Most people don’t realize that temperature extremes can lead to damaged insulin, rendering it less effective, or even ineffective in some cases. This can put you on a roller coaster of high blood sugars leading to extreme lows if you start increasing the insulin dose.

Unprotected Insulin
Insulin is at the risk of being damaged everyday - in your car, at work, while you travel or even in your bag

Millions of Americans Are Improperly Storing Insulin: And these are the side effects

When my patients tell me things like this, I know their insulin pen was not kept in the right temperature.

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. William V. Tamborlane Chief of Pediatric Endocrinology -

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. Susan B. Sloane Pharmacist, Diabetes Care and
Education Specialist

It Works to Keep Insulin Cool and Safe!
This cap works just as advertised. We use it when traveling to keep my son’s insulin cool down here in Texas and other areas of the southwest that can get quite ‘toasty’. It’s nice to store it in our fridge between uses and simply grab it on the go. It’s a great alternative to carrying a big insulated bottle with ice sticks... Thank you!

Works every time
As unlikely as it may seem, this product works as described! I have used it for a while now, and it has never failed to keep the insulin pen below higher temperatures that degrade the insulin.
Lior, T1D
This really works
This technology actually works to keep the insulin at a safe temperature in my purse, without bulky and melting ice packs. It's convenient and compact. You can put the Vivi cap over a pen needle for even more convenience. They are expensive, yes, but how much will an overheated insulin pen cost you? Highly recommended.
Kathy, T2D
The best thing for me!
Whether working out at home, or at the gym, the VIVI CAP is a must have to keep my insulin at a controlled temperature. Don’t leave the house without it!! Highly recommended to anyone who needs to keep their insulin in the car or even in a hot gym locker for hours at a time!
Mark Sloane
Great invention
When there are extreme heat waves here in my country, the VIVI Cap just saves me! It helps me keep my insulin at a normal temperature. Highly recommended!
Aviva D.
The VIVI Cap is so easy and simple!
I've lived with type 1 diabetes for over 20 years, and I worry the most about my insulin when I'm going with my kids to the beach or the pool, and I have to pack an old school ice pack in my bag and make sure that it is always in the shade. It's just tedious.. With VIVI Cap I simply throw it in my bag and go.. It's so easy!

Frequently Asked Questions

FAQ's

VIVI Cap does not require any maintenance, there is no need to charge it or to place it in the fridge. After initially fitting it to your insulin pen with one of the supplied adaptors, simply use it as your pen cap. It fits most of the prefilled insulin pens. There is a VIVI Cap available for refillable insulin pens as well.

VIVI Cap doesn’t have to be placed in the fridge. The VIVI Cap patented CLICK-N-GO technology incorporates innovative space-grade insulation with a unique heat exchanger.
It automatically absorbs the excess heat, releasing it to the environment when ambient temperature is normal. It can be placed in the fridge to accelerate the heat release, but without the insulin pen.

No, VIVI Cap does not have a rechargeable battery and does not depend on electrical power to function.
The battery in the device runs the temperature sensor and the light indicator and with proper use, can last for many years.

You can clean the exterior and interior of VIVI Cap by wiping it with a medical swab. When cleaning the interior, be careful not to tear off the internal temperature sensor (looks like a tiny black dot inside).
