For people with or without diabetes, Glucerna products should not be used to treat hypoglycemia, insulin shock, or insulin reaction because the carbohydrates from Glucerna do not elicit a large blood glucose response and would not help restore blood sugar.

What are the side effects of Glucerna?

Glucerna shakes and snacks are unlikely to cause any severe side effects. The greatest risk lies in possible overreliance on the products for diabetes management. Getting enough protein and managing your carbohydrate intake is important, but you also need to exercise regularly to maintain good blood glucose levels.

Glucerna is formulated from slow-burning carbs that are designed to be digested slowly so as not to quickly raise your blood sugar.
