I Missed My Wegovy Shot — What Do I Do?

Wegovy (semaglutide) is a prescription-only, once-weekly injectable medicine. Because it works on a weekly schedule, a missed dose is not simply carried over — the timing matters, and your prescriber or doctor is the right person to advise you on what to do next. Never double up on doses or take an extra injection to compensate; dose decisions are clinical ones.

Check your patient information leaflet first

The leaflet included with your Wegovy pen includes specific guidance on missed doses. As a general principle — and always defer to your own leaflet and prescriber over any general information — missed-dose guidance for weekly injections often depends on how many days remain until your next scheduled shot. Check the leaflet that came with your pen, or refer to the electronic Medicines Compendium (eMC) for the full Wegovy patient information.

Common questions around the injection itself

Beyond a missed dose, people often have questions about the injection in general — things like whether an arm hurts after a Wegovy shot, or noticing a small lump after a Wegovy shot at the injection site. A firm lump or localised soreness after injecting is commonly reported and is often a normal tissue response to a subcutaneous injection. That said, if any site reaction is severe, spreading, warm, or does not settle, contact your healthcare professional promptly.

On timing: some people wonder whether they can do their Wegovy shot a day early. Again, this is a question for your prescriber — only they can advise on adjusting your schedule safely, taking into account your full treatment history.

For general background on how Wegovy works and what to expect from treatment, see our overview of what Wegovy is, or visit the Wegovy guide for more on living with this medicine. If you are also curious about injection site options, our page on where to place a GLP-1 injection covers the common sites — abdomen, thigh, and upper arm — in plain language.

One of the most practical things GLP Trackr does is help you avoid missed doses in the first place. The app's dose reminder feature sends a gentle notification on your chosen injection day, so your weekly schedule stays consistent without relying on memory alone.

When you do log each shot — date, dose strength, and injection site — you build a clear record of your treatment history. If you ever do miss a dose, you have an accurate log to bring to your next prescriber conversation, rather than trying to remember weeks of dates from scratch. The app also tracks injection site rotation, suggesting your next site based on your history, which is useful for reducing localised reactions over time.

If you experience side effects around your injections — soreness at the site, nausea after a shot, or anything else — GLP Trackr's side-effect tracker lets you log symptoms and spot patterns, giving you something concrete to discuss with your prescriber at your next appointment. For more on the broader GLP-1 journey, explore our GLP-1 medication tracking hub.

Always follow the guidance of your prescriber or doctor when it comes to missed doses, timing changes, or any side effects that concern you — they know your full history and are best placed to advise. GLP Trackr helps you record and organise that information; it is not a substitute for clinical advice.

Keep your weekly injection routine consistent and your records clear — set up your dose reminders and injection log in GLP Trackr. It is free to try for 7 days on the App Store and Google Play.
