How do I titrate Semaglutide dosage?

Start with 0.25mg weekly for 4 weeks to minimize GI side effects. Increase to 0.5mg for weeks 5-8, then to 1mg if needed. For weight loss (Wegovy protocol), you can continue increasing to 1.7mg and finally 2.4mg, with each step lasting at least 4 weeks.

What day of the week should I inject Semaglutide?

Inject Semaglutide on the same day each week, at any time of day, with or without food. Choose a day that fits your schedule. If you need to change your injection day, ensure at least 48 hours between doses.

What are common Semaglutide side effects?

Common side effects include nausea, vomiting, diarrhea, constipation, and decreased appetite - especially during dose escalation. These typically improve over time. Starting with lower doses and titrating slowly helps minimize side effects.

How much water should I use to reconstitute Semaglutide?

For a 5mg vial, using 2mL of bacteriostatic water gives a concentration of 2.5mg/mL, making dose calculations simple. For example, 0.25mg would be 10 units (0.1mL) on an insulin syringe.

How long does reconstituted Semaglutide last?

Reconstituted Semaglutide stored properly in the refrigerator remains stable for approximately 4-6 weeks. Keep it protected from light and maintain consistent refrigeration between 36-46°F (2-8°C).
