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. Why training matters Wegovy (semaglutide) is designed for self-injec

The effectiveness of Wegovy often feels strongest early on as appetite settles and “food noise” quietens, but the weight curve is rarely perfectly linear. Many people see quicker losses at first, followed by slower, steadier change as the body adapts and plateaus appear — that’s normal physiology, not failure. Services use review points to check technique, adherence, side effects, and whether your plan (protein, fibre, activity, sleep) matches the new appetite pattern. If pro

Yes — mild redness, itching, or small lumps can occur and usually settle. Rotate sites weekly to prevent lipohypertrophy (fatty thickening) and avoid injecting into scars, moles, or irritated skin. If you see persistent nodules, colour changes, warmth, or pain, switch location and ask your clinician to review technique and needle size. Why skin reactions happen Wegovy (semaglutide) is injected into the fatty layer under the skin (the subcutaneous tissue), where small local re

For kidney or liver issues, the dose ladder is usually the same, but clinicians monitor more closely. No routine dose adjustment is needed for mild-to-moderate impairment, yet dehydration from nausea or vomiting can stress the kidneys, so hydration and slower titration matter. In severe impairment or if labs are changing, prescribers may pause or hold at a lower step and review more frequently. Always flag any new swelling, dramatic fatigue, very dark urine, or reduced urine

Always check the pen label to confirm the correct dose before injecting. Rotate injection sites each week to avoid irritation and avoid injecting into scarred, bruised, or inflamed skin. Use a new needle each time and dispose of it safely in a sharps container. NHS staff encourage patients to report any unexpected reactions or concerns so adjustments can be made. Checking the pen and medicine One of the simplest but most important steps is to confirm you have the correct pen
