What the Wegovy 0.25mg FlexTouch Pen Is and How the Starting Dose Works
Wegovy is supplied as a pre-filled, once-weekly injectable pen. The 0.25mg strength comes in the Wegovy FlexTouch pen — a pre-set device designed so that each injection delivers a fixed 0.25mg dose of semaglutide. You do not dial or adjust the dose yourself; the pen is pre-set at the factory for that single strength.
Why the dose starts low
Semaglutide is a GLP-1 receptor agonist that works on appetite-regulating pathways and slows gastric emptying. Starting at 0.25mg allows the body time to adapt to these effects before the dose is increased. Gastrointestinal side effects — such as nausea, indigestion, or changes in bowel habit — are most commonly reported early in treatment and during dose increases, so a gradual start is standard practice. According to the electronic Medicines Compendium (eMC), the prescribing information for Wegovy outlines a structured titration schedule; your own prescriber will follow the approach appropriate for you.
The FlexTouch injection
The Wegovy FlexTouch injection is given subcutaneously — under the skin — once a week. Common injection areas include the abdomen, front of the thigh, or upper arm. Rotating between sites with each injection is generally recommended to support skin and tissue health. For a broader look at the dose strengths available across the Wegovy range, see this overview of Wegovy dose strengths. If you are approaching or already using a higher pen, the Wegovy 1.7mg guide covers what that stage typically involves.
One pen, one dose
Each Wegovy FlexTouch pen — including the 0.25mg version — contains enough medication for a single injection. Once used, the pen is not reused for a subsequent week; a new pen is used for each dose. Check the patient information leaflet that came with your pen, or ask your prescriber or pharmacist, for specific storage and handling guidance, as conditions can affect the medicine.
Any questions about how to use the FlexTouch pen correctly, or about your injection technique, should be directed to your prescriber, pharmacist, or a healthcare professional — they can demonstrate the process in a way that written guidance cannot replicate.

Tracking Your Wegovy 0.25mg Doses with GLP Trackr
Keeping an accurate record of every injection is one of the most practical things you can do at this early stage of your Wegovy journey — and that is exactly where GLP Trackr starts.
The app's dose logging feature lets you record each injection as you give it: the dose strength, the date, and the time. At 0.25mg you are establishing a weekly rhythm, and having a clear log means you always know when your last injection was — useful both for your own peace of mind and for conversations with your prescriber. Set a dose reminder so the day never slips past unnoticed; missing or delaying a dose is worth discussing with your prescriber, and the app gives you an accurate record to bring to that conversation.
As you move through the titration schedule, the injection-site tracking feature lets you log which area you used each week and see your rotation history at a glance, helping you avoid returning to the same site too soon.
For a closer look at how doses and pens are structured across the treatment, the guide to Wegovy pen doses is a useful reference. You can also explore all Wegovy dose strengths to understand how the titration typically progresses — though any actual decisions about moving between doses belong entirely with your prescriber.
If you are also curious how Wegovy compares with tirzepatide, the Mounjaro 5mg overview gives context on how a different GLP-1 medicine approaches its own dose stages.
A note on side effects: if you experience symptoms that feel severe, persistent, or worrying at any point during treatment — including during the 0.25mg phase — contact your healthcare professional promptly. GLP Trackr can help you log what you notice and when, so you have a clear record to share, but it is not a substitute for clinical advice. Any side effects you experience should also be reported to your national pharmacovigilance scheme (such as the UK's Yellow Card scheme) and to your prescriber.

Frequently asked questions.
The Wegovy FlexTouch pen is a pre-filled, pre-set injectable pen that delivers a single 0.25mg dose of semaglutide. It is used once a week and is not reused — each injection requires a new pen. Your prescriber or pharmacist can advise on handling and storage.
Most people prescribed Wegovy begin at 0.25mg for around four weeks before their prescriber reviews whether to move to the next dose stage. The timing and any changes to your dose are always decided by your prescriber based on how you are tolerating the medicine.
Missed dose decisions should always be directed to your prescriber or doctor — do not double up or adjust your schedule without their guidance. GLP Trackr lets you log a missed dose so you have an accurate record to discuss at your next appointment.
Nausea is one of the most commonly reported side effects at the start of Wegovy treatment. Many people find it is most noticeable in the first days after an injection and eases over time. If nausea is severe or persistent, contact your healthcare professional for guidance.
GLP Trackr lets you log each injection — recording the dose strength, date, and time — and set weekly reminders so you never lose track of your schedule. You can also record injection sites to support rotation, and share a clear log with your prescriber.
