How can I tell when my Lantus and Novalog are not effectively working? Maybe they have been exposed to a higher than normal temperature and only half used.

If your blood sugar control has worsened after beginning a new vial of Lantus and/or Novolog and nothing else in your life (diet, activity, illness, stress) has changed, it's possible that the insulin isn't working effectively. Clues that insulin has been damaged are discoloration, cloudiness, or floating particles visible in the vial. However, sometimes damaged insulin doesn't look any different. If you suspect that your insulin isn't working, contact your pharmacist to discuss obtaining a replacement order.
