The WEGOVY® pen is for use by one person only. Substances added to WEGOVY® may cause degradation of semaglutide. WEGOVY® must not be mixed with other medicinal products, e.g. infusion fluids.[4]Section 12, page 29
Always remove the injection needle after each injection and store the pen without a needle attached. This may prevent blocked needles, contamination, infection, leakage of solution and inaccurate dosing.[1]Section 11, page 28

Keep away from the cooling element of the refrigerator. Protect from excessive heat and light.[1]Section 11, page 28
Before first use: Store in a refrigerator (2°C to 8°C). After first use: Store below 30°C or in a refrigerator (2°C to 8°C) for up to 8 weeks. Keep the pen cap on when WEGOVY® is not in use in order to protect from light.[1]Section 11, page 28
