Glucose tablets are good to keep on hand when you are on the go because they have a long shelf life -- about three years -- but always check the expiration date on the package. You can keep them in your bag or somewhere with you since hypoglycemia can happen unexpectedly, especially if you are busy.
Once opened, Levemir pens and vials last a little longer than average (up to 42 days) and cloudy insulins pens, such as Novolog 70/30 and Humalog 75/25, last for a shorter time (up to 14 days). The package insert that comes with your insulin specifies how long it remains good once it is opened, or you can ask your local pharmacist.
