Glucose (Glucose Monohydrate)

Glucose solution for injection is employed in clinical settings to address specific metabolic and nutritional needs.

• Management of acute hypoglycemia in patients unable to take oral glucose.
• Provision of carbohydrate calories as part of total parenteral nutrition (TPN).
• Support during peri‑operative fasting when oral intake is not possible.
• Correction of low blood glucose levels during insulin therapy or glucose‑lowering procedures.
• Dilution medium for certain intravenous medications requiring a compatible carbohydrate carrier.

Intravenous administration of glucose may be associated with a range of adverse reactions, which are generally categorized by frequency and severity.

Common

• Transient hyperglycemia or elevated blood glucose levels.
• Local irritation or pain at the injection site.
• Nausea or mild gastrointestinal discomfort.
• Fluid overload in patients with compromised cardiac function.
• Headache or dizziness related to rapid glucose changes.

Serious

• Severe hyperglycemia leading to osmotic diuresis or ketoacidosis in susceptible patients.
• Allergic reactions such as rash, urticaria, or anaphylaxis.
• Electrolyte disturbances, particularly hypokalemia, secondary to rapid glucose shifts.
• Venous thrombosis or phlebitis at the infusion site.
• Severe hyperglycemia leading to osmotic diuresis or ketoacidosis in susceptible patients.

When prescribing or administering glucose solution for injection, healthcare professionals should observe several precautionary measures to ensure patient safety.

• Assess baseline blood glucose and adjust infusion rate accordingly.
• Monitor serum electrolytes, especially potassium, during and after infusion.
• Use caution in patients with renal or hepatic impairment due to altered glucose metabolism.
• Avoid rapid infusion in individuals at risk for fluid overload or heart failure.
• Ensure sterility by using single‑use vials and discarding any contaminated equipment.
• Document infusion details, including concentration and total volume administered.
• Verify compatibility with co‑administered intravenous drugs before mixing.

Glucose solution for injection can interact with other medications or clinical conditions, influencing therapeutic outcomes.

Avoid

• Concurrent high‑dose insulin therapy without close glucose monitoring, which may precipitate severe hypoglycemia.
• Co‑administration with potassium‑sparing diuretics in patients prone to hyperglycemia, increasing risk of electrolyte imbalance.
• Use with certain radiographic contrast agents that may exacerbate hyperglycemia.

Use with caution

• Intravenous lipid emulsions, as combined caloric load may require adjustment of total nutrient provision.
• Catecholamine infusions (e.g., epinephrine) that can raise blood glucose levels, necessitating tighter monitoring.
• Medications that affect glucose metabolism such as glucocorticoids, requiring individualized dosing.
