Information for t:flex® Insulin Pump customers

The t:flex Pump is the only available pump that holds up to 480 units of insulin, and is prescribed specifically for people with greater insulin needs. The t:slim X2 Upgrade Program is only for access to the 300-unit capacity t:slim X2 Pump, so upgrades from t:flex Pumps are excluded from this specific program.
