A 5ml vial of semaglutide typically lasts 30-40 days depending on the prescribed dose

A 5ml vial of semaglutide contains approximately 1,500-2,000 units of medication. The duration depends on your prescribed dose, which commonly ranges from 0.25mg to 2.4mg weekly. At the standard maintenance dose of 1mg weekly, a 5ml vial lasts about 30-40 days. Higher doses will deplete the vial faster, while lower doses extend its lifespan.

• 0.25mg weekly: 160-200 days
• 0.5mg weekly: 80-100 days
• 1mg weekly: 40-50 days
• 1.7mg weekly: 23-30 days
• 2.4mg weekly: 16-20 days

Storage and usage considerations

Once opened, a 5ml vial should be refrigerated and used within 56 days. Always check the expiration date before use. Store at 36°F-46°F (2°C-8°C) and protect from light. Never freeze semaglutide or use if frozen.
