Yes — seasonal extremes matter. In summer, protect pens from heat; don’t leave them in cars or direct sun, and use an insulated pouch for journeys. In winter, guard against freezing (a frozen pen must not be used). Unopened pens stay refrigerated; in-use pens can usually be kept below 30 °C for the leaflet-specified period, cap on and away from light. If you suspect overheating or freezing, ask your pharmacist before using the pen. Why temperature control matters Wegovy (sema

Short training is strongly recommended and widely offered by nurses or pharmacists. A hands-on demo covers device setup, priming (if applicable), 90° angle, site rotation, and how long to hold the pen in place — five minutes of practice prevents most errors. You’ll also get storage, travel, and missed-dose guidance, and a chance to ask questions. Refresher sessions are useful if you switch strengths or pens.

Keep unopened pens in the refrigerator (2–8 °C) in their carton, away from the freezer compartment. For in-use pens, store below 30 °C, cap on, and note the 6-week in-use limit on the box so you don’t lose track. Don’t store with a needle attached, and keep all pens and sharps out of children’s reach. Why correct storage matters Wegovy is a protein-based medicine, and like other injectables, it is sensitive to changes in temperature, light, and handling. That means how you st

After first use, a pen can usually be kept below 30 °C (cap on, away from light) for up to 6 weeks — then it must be discarded, even if medicine remains. Unopened pens belong in the fridge; if they have been kept at room temperature on purpose, many packs allow a limited period out of the fridge — your leaflet sets the exact limit. Never freeze, never overheat (hot cars, radiators, direct sun), and never store with a needle attached. Why storage rules matter Wegovy (semagluti
