D50 Ampule Dextrose Content and Hypoglycemia Treatment

Standard Dosing Information

• D50 composition is 50% dextrose, meaning 50 grams of dextrose per 100 mL, which translates to 0.5 grams per mL 1

Clinical Context for Hypoglycemia Treatment

• The traditional 25-gram D50 bolus frequently causes overcorrection and hyperglycemia, making titrated lower-concentration dextrose preferable in most situations 2

Alternative Dosing Strategies

• Administering 5-gram aliquots (50 mL of D10) repeated every 1-2 minutes achieves symptom resolution with fewer adverse events 2
• Traditional 25-gram D50 boluses result in post-treatment glucose levels of 169 mg/dL versus 112 mg/dL with titrated D10 2

Safety Considerations

• Rapid or repeated D50 boluses have been associated with cardiac arrest and hyperkalemia 2

Practical Dosing Recommendations

• For conscious patients with hypoglycemia, start with 10-15 grams (20-30 mL of D50 or 100-150 mL of D10) and reassess, rather than automatically giving the full 25-gram ampule 2
