Answers to some frequently asked questions to help you stay on track with V-Go

As you get started on V-Go, you may have a few questions. Here is a list of answers to a few common questions other V-Go users have asked.

Can I wear the same V-Go for more than 24 hours?

After 24 hours, you should apply a new filled V-Go. Be sure to change your V-Go at the same time every day. If V-Go is worn for more than 24 hours, it may no longer deliver the steady rate of insulin you need.

Will V-Go stick for 24 hours?

Yes, V-Go has been designed for 24-hour use. When applying V-Go, keep the following tips in mind:

  • Choose to wear V-Go on a flat surface of your body and avoid any folds in the skin
  • Be sure to thoroughly clean the site you choose to wear V-Go with an alcohol swab and let dry
  • Keep in mind that lotion and/or ointment may prevent V-Go from sticking to your skin
  • Do not touch the adhesive pad before you attach the V-Go to your skin
  • Avoid areas with excessive hair or shave the area to help V-Go attach to your skin
  • You may choose to use a Cavilon No Sting Barrier Film wipe to create a thin film barrier on the skin to help your V-Go stick

If your V-Go does not remain secure for the full 24 hours -- replace with a new, filled V-Go.

If I require less insulin than my V-Go holds, do I have to completely fill the whole thing?

Yes, for the V-Go to work properly you must fill it completely.

How do I know if my V-Go is full?

Hold the viewing window at eye level and direct the backside of the EZ Fill toward a brightly lit area. Ideally, you should see only fluid and no air space. You may also see tiny air bubbles smaller than a grain of rice, which are okay.

What if my V-Go is not completely full?

If your V-Go is not full, check to make sure the insulin vial is completely pushed down into the insulin vial holder and that the EZ Fill drawer is completely closed. Also, be sure that you have completely pulled the plunger to its full upright position, and that you are not pushing it down too quickly. Lastly, ensure that you have not run out of insulin. If you are out of insulin, remove the empty insulin vial from the EZ Fill insulin vial holder, replace with a new vial, and refill V-Go.

Where should I store V-Go once filled with insulin?

To help maintain a consistent daily routine, you should apply V-Go immediately after filling. However, V-Go may be filled with Humalog® for up to 24 hours prior to use if refrigerated or if left at room temperature. V-Go may be filled with NovoLog® for up to 5 days prior to use if refrigerated, or for up to 3 days prior to use if left at room temperature.

What if I run out of insulin at mealtime?

First check that you are pressing the Bolus Ready Button fully. If the Bolus Delivery Button fails to pop out after you activate the Bolus Ready Button, you have used all of the available insulin for bolus dosing (36 units or 18 clicks per 24 hours). After 18 clicks, the Bolus Delivery Button will pop out and lock, preventing further bolus doses. If any of this occurs, replace the empty V-Go with a new filled V-Go before your next meal. Plan your day so that you have enough insulin for each meal. You should also create a plan with your healthcare professional on how to manage your bolus (mealtime) dosing with V-Go, including what to do if you run out of insulin at mealtimes.

Should I wear V-Go to bed?

Yes – you should wear V-Go for a full 24 hours, even while you sleep.

Can I swim, shower, or bathe while wearing the V-Go?

Yes, V-Go has been successfully tested in water to depths of 3 feet, 3 inches (1 meter) for 24 hours, and can be worn during normal daily activities, such as showering and bathing as well as activities near the surface of the water, such as swimming. V-Go should not be used in water activities below 3 feet, 3 inches (1 meter), such as scuba diving or extremely hot water temperatures, such as hot tubs or whirlpools.

How do I travel with the V-Go?

V-Go can safely be worn on an airplane, and the V-Go device and supplies can go through airport security.

When traveling, use the same precautions that you would when traveling with other insulin supplies and talk with your healthcare professional about extra precautions you may need to take. When traveling with the EZ Fill, with an insulin vial attached, it should be refrigerated at all times. Contact your insulin manufacturer regarding guidelines for travel and pack in a very secure place (avoid impact from shaking, jarring). Remember, empty V-Go devices do not require refrigeration.

Important Risk Information
If regular adjustments or modifications to the basal rate of insulin are required in a 24-hour period, or if the amount of insulin used at meals requires adjustments of less than 2-Unit increments, use of the V-Go Disposable Insulin Delivery Device may result in hypoglycemia. The following conditions may occur during insulin therapy with V-Go: hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose). Other adverse reactions associated with V-Go use include skin irritation from the adhesive pad or infections at the infusion site. V-Go should be removed before any magnetic resonance imaging (MRI) testing.
