Yes, V-Go should be worn for a full 24 hours, even during sleep.
No, after 24 hours, patients should apply a new filled V-Go because the used device may no longer deliver a steady rate of insulin.
Yes, V-Go has been designed for 24-hour use. When applying V-Go, keep the following tips in mind:
If V-Go does not remain secure for the full 24 hours, replace with a new filled 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 has not been tested and therefore should not be used in the following conditions:
Remove V-Go prior to scuba diving, hot tub use, or whirlpool use and replace with a new filled V-Go afterward.
V-Go can safely be worn on an airplane, and V-Go device and supplies can go through airport security.
Use the same precautions exercised with other insulin supplies. A few things to remember:
No, V-Go must be completely filled each day to work properly.
Hold the viewing window at eye level and direct the backside of the EZ Fill toward a brightly lit area. Ideally, one should see only fluid and no air space, though tiny air bubbles smaller than a grain of rice are OK.
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 the plunger is pulled to its full upright position, and that it is not pushed down too quickly. If V-Go runs out of insulin, remove the empty vial from the EZ Fill insulin vial holder, replace with a new vial, and refill V-Go.
This is normal. As V-Go is filled, extra pressure may be required to push the plunger down completely.
To help maintain a consistent daily routine, V-Go should be applied immediately after filling. However, V-Go may be filled with Humalog® for up to 24 hours prior to use if refrigerated or 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.
First check that the Bolus Ready Button is fully pressed. If the Bolus Delivery Button fails to pop out after the Bolus Ready Button has been activated, then the available insulin for bolus dosing (36 Units or 18 clicks per device) has been spent. The Bolus Delivery Button is designed to pop out and lock after 18 clicks, preventing further bolus doses. If this occurs, replace the empty V-Go device with a new filled V-Go before the next meal. Patients should plan each day accordingly to ensure they have enough insulin for each meal. They may require professional guidance with planning and managing their bolus dosing as well as anticipating what to do if they run out of insulin at mealtimes.
