Hypoglycemia and hydroxyurea (Hydrea™, Apo-Hydroxyurea™, Mylan-Hydroxyurea™* hydroxycarbamide):  Medications with hydroxyurea could result in falsely elevated sensor glucose readings in Medtronic and Dexcom sensors (2021). Not Libre. see here)

Insurance coverage for CGM varies. Patients are asked to have their insurance companies check under "Glucose Meters" and "Medical Devices". Patients with no insurance coverage are encouraged to contact their employer's human resources department, as the employer determines the coverage available for their employees.
