Understanding Semaglutide Dosages and Vial Sizes

Calculating the Lifespan of Your 2ml Semaglutide Vial
To determine how long your 2ml vial will last, you need to know the concentration of your semaglutide solution. Let's illustrate with examples:
Example 1: 1mg/ml Semaglutide
- A 2ml vial contains 2ml * 1mg/ml = 2mg of semaglutide.
- If your prescribed dose is 1mg per week, the vial will last for 2 weeks.
- If your prescribed dose is 0.5mg per week, the vial will last for 4 weeks.
Example 2: 2mg/ml Semaglutide
- A 2ml vial contains 2ml * 2mg/ml = 4mg of semaglutide.
- If your prescribed dose is 1mg per week, the vial will last for 4 weeks.
- If your prescribed dose is 2mg per week, the vial will last for 2 weeks.
What Happens After the Vial is Opened?
Once opened, semaglutide vials have a limited shelf life. The manufacturer's instructions will specify the duration of usability after the first use. Typically, this is a few weeks. Never use semaglutide after the expiration date printed on the vial or after the recommended time post-opening, even if some medication remains. Discard the vial appropriately according to your pharmacist's instructions.
How to Properly Store Your Semaglutide Vial
Proper storage is crucial for maintaining the efficacy and safety of your semaglutide. Keep the vial refrigerated as instructed on the label. Avoid freezing.
