Pharmacy Labels for Gliclazide (Sulfonylurea)

Pharmacy labels for gliclazide should include warnings about hypoglycemia risk, instructions to take with meals, and specific dosing information based on the formulation (immediate-release or modified-release). 1

Essential Label Information

  • Medication Name and Strength: Clearly state "Gliclazide" and the strength (e.g., 30 mg modified-release or 80 mg immediate-release) 1, 2

  • Dosage Instructions:

    • For modified-release: "Take once daily in the morning with breakfast" 3, 2
    • For immediate-release: "Take with meals" (divided doses if >80 mg daily) 2
  • Maximum Daily Dose Warning:

    • Modified-release: "Do not exceed 120 mg daily" 2
    • Immediate-release: "Do not exceed 320 mg daily" 1, 2
  • Hypoglycemia Warning: "May cause low blood sugar. Carry quick-acting sugar source at all times" 1, 4

Additional Important Warnings

  • Kidney Function: "Use with caution if you have kidney problems; initiate at lower doses if kidney function is reduced" 1

  • Alcohol Warning: "Avoid alcohol consumption while taking this medication as it may cause unpredictable blood sugar levels" 4, 5

  • Driving/Operating Machinery: "May cause dizziness or drowsiness. Use caution when driving or operating machinery until effects are known" 4

  • Storage Information: "Store at room temperature away from moisture and heat" 2

Special Considerations

  • Elderly Patients: "Elderly patients should start with lower doses and monitor blood sugar more frequently due to increased risk of hypoglycemia" 4, 2

  • Missed Dose Instructions: "If you miss a dose, take it as soon as you remember. If it's almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take double doses" 4

  • Drug Interactions: "Inform your doctor of all medications you are taking, especially other diabetes medications, as dose adjustments may be needed" 1, 5

  • Refill Information: Include the number of refills authorized and expiration date 1
