Factors Affecting Semaglutide Vial Longevity
1. Expiration Date and Manufacturer Guidelines
Semaglutide vials are labeled with an expiration date, which should be the first indicator of its shelf life. Unopened Semaglutide vials should not be used past this date. The manufacturers rigorously test the stability of the medication under various conditions to determine this date, ensuring the safety and effectiveness of the medication up to this point.
2. Storage Conditions
Improperly stored Semaglutide vials should be disposed of immediately. However, mind that Semaglutide injections can remain effective even if exposed to temperatures as high as 104°F (40°C) for up to three days. If your vials arrive warm, they are still safe to use, provided you transfer them to refrigerated conditions of 36-46°F (2-8°C) immediately upon receiving.
Opened Semaglutide vials last for up to 56 days if stored in the refrigerator between 2°C to 8°C or at room temperature below 30°C. Unopened vials should be refrigerated only and last till its expiry, except Wegovy which can be kept at room temperature if necessary and can last up to 28 days. It’s critical to keep the vial away from light and to avoid freezing it, as this can degrade its effectiveness.
3. Handling Practices
Proper handling of Semaglutide is crucial. Avoid shaking the vial vigorously as this can affect the medication’s integrity. Always use sterile needles and practice good hygiene when administering injections to prevent contamination. Improperly handled vials won’t last long.
4. Dosage Regimen
The primary determinant of how long a vial of Semaglutide lasts is the prescribed dosage. Semaglutide is typically administered once a week, and the dosage can vary based on the specific needs of the patient.
Common starting doses for Semaglutide, for instance, are 0.25 mg per week for the first four weeks, followed by an increase to 0.5 mg. Depending on the therapeutic goals, the dose can be further increased to 1 mg (higher maintenance dose) or 2.4 mg per week (primarily for weight management under the brand name Wegovy)
| Brand and Concentration | Dose | How long will one vial last? |
| Ozempic:1.5 mL vial contains 2 mg of Semaglutide | 0.25 mg/ weekly | 8 weeks |
| 0.5 mg/ weekly | 4 weeks | |
| Wegovy:4 mL vial contains 10 mg of Semaglutide | 2.4 mg /weekly | 4 weeks |
5. Vial Concentration and Size
The concentration of Semaglutide in a vial also plays a critical role. For example, Ozempic is available in different strengths, such as 1.5 mg/1.5 mL (1 mg/mL) and 4 mg/3 mL (1.34 mg/mL). The size of the vial dictates how many doses can be extracted. Typically, a single vial of Ozempic contains multiple doses.

Always adhere to the storage instructions and use the medication within the recommended period after opening. If in doubt, consult your healthcare provider for guidance on how to manage your Semaglutide treatment effectively.
