FAQs to Help Patients Stay on Track with V-Go®

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:

• Choose to wear V-Go on a flat body surface and avoid any folds in the skin
• Once a location to adhere V-Go is chosen, thoroughly clean the surface with an alcohol swab and let dry
• Keep in mind that lotion and/or ointment may keep V-Go from sticking to skin
• Do not touch the adhesive pad before attaching V-Go to the skin
• Avoid areas with excessive hair or shave the area to help V-Go attach to skin

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:

• Water activities below 3 feet, 3 inches (1 meter), such as scuba diving
• Extremely hot water temperatures, such as hot tubs or whirlpools

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:

• The EZ Fill with an insulin vial attached should be refrigerated at all times. Contact the insulin manufacturer regarding guidelines for travel. Pack in a secure location that is free from shaking, jarring, and impacts
• Empty V-Go devices do not require refrigeration
• If the patient is going on a short trip and does not wish to take their EZ Fill, they should be familiarized with all V-Go storage information

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.
