What If You Miss Multiple Doses?
If you've missed more than one dose in a row, don’t just pick up where you left off.
Official guidance is clear: Speak to your prescriber.
Your doctor may recommend restarting at a lower dose to reduce the chance of side effects. This is because your body needs time to readjust to the medication, especially if you've been off it for several weeks or longer.
It might feel frustrating to go backwards in dose, but it’s about safety, and it’s better to have a plan than risk feeling miserable.
Does Missing a Dose Mean You’ll Lose Progress?
One missed injection won’t make you “fail.”
You might notice appetite control softening slightly in the days before your next injection, but that doesn’t mean all progress is lost. These meds work cumulatively. Staying consistent over months matters more than being perfect every single week.
Planning Ahead
If you know you have a busy week coming up, or you’re travelling:
Set a phone reminder for injection day.
Keep your pen stored safely, in the fridge or an insulated travel pouch if needed.
Talk to your prescriber in advance if you think you might miss more than one dose.
A little planning can help you keep your routine without last-minute stress.
TL;DR
Missing a GLP-1 dose happens.
✅ For Ozempic and Wegovy:
If you’re 5 days or less late, take it as soon as you remember.
If more than 5 days, skip it and wait for your usual scheduled day.
✅ For Mounjaro:
If you’re 4 days or less late, take it as soon as you can.
If more than 4 days, skip it and wait for your next scheduled day.
Always keep at least 3 days between doses.
✅ Missed multiple doses?
Speak to your prescriber. You may need to restart at a lower dose.
Above all, remember:
You don’t have to be perfect. You just have to keep going.
This is a long-term journey, and you’re doing the best you can.
And if you’re ever in doubt?
Check your medication leaflet, talk to your pharmacist, or speak to your prescriber. They’re there to help you stay safe and supported. 💛
Official Patient Leaflets for Reference:
About These Links
These patient leaflets are hosted on the Electronic Medicines Compendium (EMC), which is the official UK platform for publishing the manufacturer-approved patient information leaflets and summaries of product characteristics for licensed medicines.
The EMC is operated by Datapharm, working in partnership with the UK medicines regulator, the Medicines and Healthcare products Regulatory Agency (MHRA).
It’s the trusted source doctors, pharmacists, and patients use to access the exact guidance that manufacturers have submitted and that UK regulators have approved, ensuring you’re getting the most accurate, up-to-date, and safe instructions for your medication.
The Official Guidance
What you should do depends on which medication you’re using and how late you are.
Ozempic and Wegovy
These two semaglutide-based medications have the same rules:
If it's 5 days or less since your scheduled injection:
Take the missed dose as soon as you remember. Then return to your usual weekly schedule, even if that means your next injection is sooner than normal.
If it's more than 5 days late: Skip the missed dose entirely.
Just wait and take your next injection on your usual scheduled day.
Official sources:
Why? These medications are designed to maintain steady levels in your system over time. The 5-day window gives you flexibility without throwing off your overall treatment plan.
Mounjaro
Mounjaro (tirzepatide) has slightly stricter timing:
If it's 4 days or less since your scheduled injection:
Take the missed dose as soon as possible. Then return to your usual weekly schedule.
If it's more than 4 days late:
Skip the missed dose. Wait for your next scheduled injection day.
Important note:
The minimum time between two Mounjaro doses must be at least 3 days.
Official source:
Why? These guidelines help maintain the once-weekly rhythm without doses getting too close together, which could increase side effects like nausea or digestive upset.

Forgot your weekly jab? You’re not alone.
Life gets busy, and it’s surprisingly easy to let an injection day slip by.
The good news? Missing one dose doesn’t ruin your progress. But there are official guidelines for what to do next, and following them helps you stay safe and consistent on your journey.
Let’s take a look at the official guidance.
First Things First: Don’t Panic
A missed dose isn’t a crisis.
GLP-1 medications work over time to help manage appetite, cravings, and food noise. They’re designed for steady, long-term use, and one slip-up won’t erase your hard work.
The key is to handle it the right way, so you can get back on track without confusion or risk of side effects.
