Once a Week, Every Week: How the Schedule Works
Both Mounjaro and Wegovy are designed as once-weekly injectable medicines. You choose a day that fits your routine — many people pick a day when they are at home and unhurried — and inject on that same day each week. Consistency matters: keeping a regular seven-day gap helps maintain steady levels of the medicine in your body.
What about the maintenance dose?
A maintenance dose is simply the dose level your prescriber determines is right for you for the longer term, once any titration period is complete. The frequency does not change — it remains once weekly regardless of which dose strength you are on. Decisions about when you have reached a maintenance stage, and what that dose should be, rest entirely with your prescriber.
Does the schedule ever change?
The once-weekly injection schedule is the standard for both Mounjaro and Wegovy. There is no standard twice-weekly or daily version of these medicines. If you ever have questions about whether your schedule should change — for example around a planned procedure, travel, or a side-effect concern — that conversation belongs with your prescriber or doctor, not a general guide.
If you are curious about how long you might be taking this medicine, it is worth reading about whether you need to take Mounjaro indefinitely and what staying on Mounjaro long-term involves — both of which are separate questions from the weekly schedule itself.
For a broader overview of living with Mounjaro, the Mounjaro guide covers the full picture.

Keeping Track of Your Weekly Dose with GLP Trackr
Remembering which day you injected — and making sure you never accidentally miss or double up — is where a dedicated tracking tool earns its place. GLP Trackr's dose-logging feature lets you record every injection the moment you take it: the date, the dose strength, and the injection site. Because the record is always there, you never have to rely on memory alone.
The app also includes a gentle reminder system so your weekly injection day stays front of mind without you having to think about it. And if you ever do miss a dose, the app lets you log that too — giving you a clear record to discuss with your prescriber rather than trying to recall the gap later.
Alongside dose tracking, GLP Trackr captures the wider picture of your week: weight, energy, mood, and any side effects you notice. Over time, that full log becomes something genuinely useful to bring to your next prescriber appointment.
If you are wondering about starting age or other eligibility questions, there is also information on how old you need to be to take Mounjaro.
A note on safety: any question about your specific dose, timing, or what to do if something feels wrong should go to your prescriber or doctor — they have your full medical history and are the right person to advise you. GLP Trackr helps you record and organise your journey; it is not a substitute for clinical guidance.

The Most Advanced GLP-1 Brain Ever Built.
The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.
Knows Your Cycle
GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

Frequently asked questions.
Mounjaro is injected once a week, on the same day each week. The once-weekly schedule applies at every dose stage, from the starting dose through to any maintenance dose your prescriber decides on.
Wegovy (semaglutide) is also a once-weekly injection, taken on the same day each week. Like Mounjaro, the frequency stays consistent throughout treatment regardless of the dose strength you are on.
No — the once-weekly schedule stays the same even at a maintenance dose. The dose strength may be different from where you started, but your prescriber determines that; the injection day and frequency do not change.
Any decision about what to do after a missed dose should come from your prescriber or the patient information leaflet for your medicine — not a general guide. You can log a missed dose in GLP Trackr to keep your record accurate and discuss it at your next appointment.
Yes. GLP Trackr includes dose reminders so your weekly injection day stays on your radar. You can also log each injection — date, dose, and site — so you always have an accurate record without relying on memory.
