Why a Break Changes How You Restart
Wegovy (semaglutide) works by acting on GLP-1 receptors involved in appetite regulation and digestion. When you stop taking it — even for a month or four weeks — the medicine clears from your system and your body loses the tolerance it had built up to its effects. This is why simply picking up where you left off at your previous dose can increase the chance of gastrointestinal side effects such as nausea, vomiting, or digestive discomfort.
What typically happens after a month off
After approximately four weeks without a dose, many prescribers advise restarting at an earlier point in the titration schedule rather than the dose you had reached. The longer the break — whether that is one month, three months, or longer — the more likely a full or partial restart from a lower dose becomes. Some people ask can I stop Wegovy after 1 month and simply resume later; clinically, a planned pause is different from an unplanned one, and both should be discussed with your prescriber before stopping or restarting.
Longer breaks: restarting after 3 or 4 months
If your break has stretched to restarting Wegovy after 3 months or more, the principle is broadly the same but the reset is likely to be more pronounced. Tolerance fades over time, and reintroducing the medicine too quickly raises the risk of more pronounced side effects. Again, your prescriber is the right person to map out the schedule — this is not a decision to make based on a general article alone.
If you are also considering a switch between medicines, our page on moving to Wegovy after Mounjaro covers some of the considerations involved, and our general Wegovy overview may be a useful reference. For those who have also taken breaks from tirzepatide, restarting Mounjaro after a short break follows similar principles.

Tracking Your Restart with GLP Trackr
When you restart Wegovy, keeping a clear log of every dose — the date, the strength, and how you feel afterwards — gives you and your prescriber a precise picture of how your body is responding. This is exactly what the dose and injection logging in GLP Trackr is built for.
Log each injection as you take it, including the site (abdomen, thigh, or upper arm), and the app tracks your rotation history so you are not returning to the same spot too soon. If side effects resurface during your restart — nausea, fatigue, digestive changes — the side-effect tracker lets you note what you experience and when, so patterns become visible over time. That record can be genuinely useful to bring to your next prescriber appointment.
GLP Trackr also sends gentle dose reminders, which is especially helpful when you are re-establishing a weekly routine after a gap. It is easy to lose track of day-of-week when you have been off schedule.
Start logging your restart journey on iOS or Android — GLP Trackr is free to try for 7 days on the App Store and Google Play.
For a broader look at tracking your semaglutide journey, our GLP-1 medicine tracking hub covers the full picture of what the app can help you manage.
A note on safety: GLP Trackr helps you record your journey so you can have better conversations with your prescriber — it is not a substitute for their guidance. If you experience severe, persistent, or worrying symptoms when restarting Wegovy, contact your healthcare professional promptly. Any decision about which dose to restart on belongs with your prescriber, never based on a general article alone.

Frequently asked questions.
This is a decision for your prescriber or doctor. After around one month off, many clinicians recommend restarting at a lower dose to let your body readjust and reduce the risk of side effects. Never change your dose schedule without guidance from your prescriber.
Whether to stop or pause Wegovy is a medical decision that should be made with your prescriber. Stopping without guidance is not recommended. Your prescriber can advise on the safest way to pause or discontinue based on your individual health history.
After a longer break, the medicine will have fully cleared your system and tolerance will have reset. Most prescribers advise restarting from an early point in the titration schedule. The exact restart dose should always be confirmed by your prescriber.
GLP Trackr lets you log each dose, date, injection site, and any side effects as you restart. This creates a clear record to share with your prescriber and helps you re-establish your weekly routine with dose reminders. Available free for 7 days on iOS and Android.
