What are the side effects of glucose supplements?

Glucose is a natural sugar that provides cells with energy. Many glucose supplements and gel (jelly-like) products are available. You should always discuss taking these products with your doctor before using them. In small doses, no side effect problems are expected. If used in large doses, however, hyperglycemia may occur. In any dose, the products could cause nausea and stomach upset because they are concentrated glucose products.

But if more serious side effects occur, immediately contact your doctor. TThe most serious side effect possible would be severe allergic reactions to some ingredient in the supplement other than the glucose itself. Symptoms of a severe allergic reaction include:
  • Rash
  • Hives
  • Itching
  • Difficulty breathing
  • Tightness in the chest
  • Swelling (of the mouth, face, lips or tongue)
