What You Need to Know About Wegovy Pens and Dosage
Wegovy pens come in several dose strengths — commonly 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg — with each pen pre-filled for a single weekly injection. The pen is designed so that no mixing or drawing up is required; it is ready to use as supplied.
How dosage works
Wegovy dosage is prescriber-led. Most people start at a lower strength and move through a titration schedule — a staged increase over several months — as directed by their prescriber or doctor. The pace and end-point of that schedule is an individual clinical decision, not something to adjust on your own. If you have questions about where you are in your dosage schedule, your prescriber is the right person to ask.
Injection sites
Wegovy is injected under the skin (subcutaneously). Common sites include the abdomen, the front of the thigh, and the upper arm. Rotating between sites each week is generally recommended to reduce the chance of skin reactions at any one area. Your patient information leaflet and prescriber can advise on technique. If you are comparing how Wegovy pens work alongside another injectable medicine, you may find it useful to read about Mounjaro pens for context.
Storing and disposing of your pen
Always check the leaflet that came with your pen for the most accurate storage guidance — but pens are typically stored in a refrigerator before first use, and may be kept at room temperature for a limited period once in use. Used pens contain a needle and must be disposed of safely; a guide to disposing of Wegovy pens covers the practicalities in detail, and you can also read about where to dispose of Wegovy pens near you. Never put used pens in household waste.

Tracking Your Wegovy Pens With GLP Trackr
One of the most practical things you can do alongside your weekly injection routine is keep a clear log of every dose — and that is where GLP Trackr is built to help.
The app's dose and injection-site logging lets you record each injection as you go: the date, the dose strength, and the site you used. Based on your history, GLP Trackr then suggests your next rotation site automatically, so you are not trying to remember whether you used the left side last week. For a once-weekly medicine like Wegovy, a gentle dose reminder can also be the difference between staying on schedule and an accidental missed injection.
If you notice anything after an injection — a skin reaction at the site, or any other symptom you want to keep track of — the app's side-effect log lets you record it with a timestamp, building a picture you can share with your prescriber at your next appointment.
If you are also interested in how GLP-1 medicines compare more broadly, the Mounjaro hub covers tirzepatide in detail.
Always follow the guidance of your prescriber or doctor — they know your full medical history and are the right person to advise on your dose and injection routine. GLP Trackr helps you record and reflect on your journey; it is not a substitute for clinical advice. If you experience any symptom that is severe, persistent, or worrying, contact your healthcare professional promptly. Any side effects worth noting can also be reported to your national reporting scheme (such as the UK's Yellow Card scheme).
